Original subtitles

(They are serious about triathlon.)

(Introducing Iron Girls)

(A movie...)

(where four women give it a go...)

(at triathlon)

The characters are decided.

(Complete the race no matter what!)

(They passionately aim to complete the race)

(Before the proper training,)

(they check their current state.)

(From the basic stamina test,)

Okay.

(they check...)

(the girls' current physical strength.)

(The final test was...)

(running 5km.)

(Even in the heavy rain,)

(they did not stop.)

(They supported each other...)

(and supported themselves.)

(Iron Girls successfully ran 5km.)

(The test is over.)

(Now, they are onto the actual training.)

(Grunting)

(The first training makes them run out of breath and scream.)

(Prepared by ruthless people)

This is insane.

(What is today's nightmarish training?)

We arrived at an amazing-looking place.

We've arrived at our lodging.

This is amazing.

(They arrive at their lodging.)

There are more stairs.

No way. Are you serious?

Hold on. My knees hurt.

(Stairs welcome them.)

- Wait. - Goodness.

(Groaning)

They must be wondering why young people are groaning.

Look at our legs.

(With their bodies exhausted from the running)

- I seriously can't go up. - Hold on.

(They barely manage to enter the lodging.)

- There are foam rollers. - Exactly.

That's nice.

I need to use a foam roller.

Let's take some medicine first.

Seo Yeon.

Wait, take them together. Or do you want them separately?

- No. - This is a painkiller.

Anyone with an indigestion? Say it now.

- You really... - Really...

(Look at what she brought.)

This is a pharmacy.

(She brought a whole pharmacy.)

Look at how organized this is.

You organized them so neatly.

One? Two?

- Two. - Two.

- I need two as well. - Two.

(UIe takes care of the members exhausted from running in the rain.)

- This is cold medicine. - Just take them all.

Wait.

(She prescribes cold medicine to In Ah who has a slight fever.)

This is a painkiller.

- I don't think I can take it now. - You don't think so, do you?

(She prescribes painkillers to Seo Yeon and Ju Hyun...)

(who have bad muscle aches.)

(That is not the end?)

Where does it hurt?

- Where? - Wait.

Below there. That part hurts too.

It was too strong.

- It hurts so much. - I didn't press that hard.

Is this where it hurts from running today?

Ju Hyun, focus.

Gosh, it's cold.

It stings so badly.

(After Ju Hyun who came to UIe as soon as the Pain Medicine opened)

- Does it hurt here? - Yes, totally.

I'll paste it here.

(She prescribes a pain relief plaster to In Ah.)

Under the shoulder blades.

- Here? - On the left, yes.

- Do you mean here? - Yes.

- Yes, there. - Here?

- I'll paste them here and here. - Yes.

(That's it!)

What would we have done without Doctor UIe?

I'm not a doctor.

(What would they have done without Doctor UIe?)

It hurts there.

It hurts.

(She finishes it with a cold spray.)

- It's done. - I'll paste it for you.

(Sweet Doctor UIe finishes the treatment.)

- Me? - Yes.

My knee hurts.

- I can paste it on my own. - I'll give you a present.

- UIe. I even wrote you a letter. - Seo Yeon.

UIe. I even wrote you a letter.

Seo Yeon.

How can you guys prepare all these?

(Moved)

- Goodness. - You didn't have to.

In Ah.

- Thank you so much. - I even wrote you a letter.

- Amazing. - Here.

- She... - It's a present.

- She even wrote us a letter. - There's a letter too.

(Surprised)

What's this?

(Tearing up)

I really hope we'll all read this.

It's a book by Murakami Haruki.

It'll help us a lot if we read this.

My goodness.

My gosh.

(Seo Yeon's consideration contained in the letters)

One, two, three.

- Thank you. - You're welcome.

- I'll go to bed first. - I...

- Here. - The treatment is over.

- Good night. - Good night.

- You did well today. - You did well today.

Shall we use the foam rollers?

(Time to loosen up their muscles using foam rollers)

(They are loosening up their muscle knots.)

It was no joke. I was known for my thighs.

Yes, I remember.

(Chatting)

(They talk a lot and get to know each other.)

(The first night of lodging together)

(After a long chat, they go to bed at dawn.)

(Or so we thought.)

A time slip, what is it?

Just like how people stop when you stop time and space,

I suddenly...

"Get in."

(They cannot stop talking tonight.)

(Next day, an early morning with a thick sea fog)

(Next day, an early morning with a thick sea fog)

(Someone is already awake.)

(It is Seo Yeon, the oldest member.)

(She is preparing something in the kitchen.)

(Rustling)

(UIe and In Ah wake up too.)

Good morning.

(To the younger members who appeared in fresh faces)

- Good morning. - I'm starting now.

What I'm going to cook...

What is this?

- It's octopus oats porridge... - Octopus?

and braised abalone.

- In the morning? - Yes. It won't take long.

Did you bring abalones?

They're all here.

(Here)

They're from Jeju Island.

I got them delivered to here.

(The forerunner of healthy meal, Jin Seo Yeon's...)

(octopus oats porridge and braised abalone)

I love abalones.

(Surprised gasp)

Why are the abalones so big?

- Because they're wild. - That's incredible.

When did you prepare this?

(You're still just an abalone.)

(Let's go, my forearms.)

(I'll show you the strength of the strength queen.)

(Scrubbing powerfully)

This is how you wash it.

(Abalone, you are pretty pale.)

It's turning white.

Is this how you always eat it?

(Thanks to the younger members who joined in scrubbing)

(Scrubbing)

- Seo Yeon, is this enough? - It's enough. It's done.

You need to be thorough when cleaning abalones.

(Score them so the sauce seeps in well.)

(What about the octopus?)

I removed the eyes.

Look at this. Do you know what this is?

- The mouth? - The teeth.

The teeth.

(She removes the teeth too.)

Pull them out like this.

I just need to scrub it all over like this, right?

Yes, that's right.

(Scrub it with flour and salt.)

(Then wash it cleanly with water.)

(Octopus and abalones are ready to be cooked.)

Ju Hyun, can you cook?

- I like cooking. - Do you?

Shall I cut them separately?

Yes, cut them vertically.

What are we cooking, actually?

Braised abalone and octopus oats porridge.

Is the braised abalone going to be bland?

Yes.

You don't like it seasoned strongly, do you?

Goodness.

I can make it salty too.

- Shall we do that, then? - Then please do that.

Okay.

I'll make it salty.

Then for today, let's follow your style.

Yes. Everyone, change what you like.

- Shall we have it bland? - Let's do that.

Okay. I'll like it from now on.

When you steam seafood,

add soju or rice wine.

It removes the fishiness.

Korean cuisine uses either soy sauce or gochujang as the sauce base.

The perilla seed oil looks good.

Some minced garlic.

Stevia.

This is amazing.

It's so cool. It looks good.

Gosh, it looks so delicious.

(Salivating)

(What is it?)

My goodness.

(Well-steamed, golden brown)

It looks delicious.

(The sauce is poured on the well-steamed abalones.)

I normally skip breakfast, but I'm salivating now.

Doesn't it look very tasty?

And steam it again so the sauce sips in.

This is almost done.

We just need to boil the octopus, and we're done.

Try that first.

That's what I mean by whole-food plant-based diet.

I had that for breakfast.

If you guys like it, you can have that for breakfast.

Do you know what's the cure...

(During yesterday's break time)

to skin diseases?

You must stick to a whole-food plant-based diet.

What do you mean by whole-food plant-based diet?

You only steam or roast...

the food in its natural state.

(A passionate lecture of the forerunner of healthy food)

(Today morning as well,)

(she made them beforehand.)

(She enjoyed it leisurely.)

(Seo Yeon's favorite breakfast menu, whole-food plant-based diet)

- Thank you for the food. - Sure.

Thank you.

(But this...)

(Eggs)

(Mushrooms)

(Carrots)

- I'm very curious about mushrooms. - Me too.

Eat up.

(Is this delicious?)

(Let's try it.)

The mushroom tastes amazing.

(No way. How is this a mushroom?)

- How is it? - Seo Yeon, the mushroom is...

(How does the mushroom taste?)

so delicious.

It's good, right?

(Satisfied)

(She tries a carrot now.)

It tastes like braised beef.

The carrot really tastes good.

(Then I'll put it right into my mouth.)

(She frowns because it tastes so good.)

I don't like to eat carrots.

Just try a little bit.

(Please try it.)

Why does this taste sweet?

The carrot is good.

- It's good. - Among the carrots...

- I've eaten so far in my life... - It's good, isn't it?

I told you it's good.

Everyone, I guess it tastes all right to you.

No, it just tastes perfect.

- It's so good. - So good.

Send me the recipe for this sauce.

It's very simple.

(The sauce ratio is very simple.)

Minced garlic, soy sauce,

perilla seed oil, olive oil,

and a bit of allulose.

Send it to me via text. I'm serious.

- Isn't it so simple? - It tastes so good.

This is insane.

I didn't know carrots could taste like this.

This is so good.

(Cook an octopus in boiling water.)

This is how you cook an octopus nicely.

You boil it like this.

(By pushing and pulling the octopus,)

(she cooks the octopus nice and plump.)

(It's easy to cook an octopus in a flower shape.)

You heat up the pan and stir-fry this first.

And then stir-fry onions and carrots.

(Pouring broth)

(Add the octopus broth to the stir-fried vegetables.)

(Season with soy sauce, perilla seed oil, and minced garlic.)

- I'm almost done. - Okay.

You're going to eat only a small amount, right?

No, I'm not.

(Adding a lot of oatmeal)

The octopus tastes like squid when it's boiled.

(Add boiled octopus.)

(Adding salted shrimp)

(Add eggs and mix well.)

All right.

(The savory smell fills the air.)

(Finally)

- I'm almost done. - It's steaming.

(Drizzling)

(Olive oil, soy sauce,)

(and perilla seed oil are added to the pan.)

(Make cuts on the octopus legs.)

- Ground pepper? - You said you ran out of it.

(Brown the legs.)

- Good. Thank you for your work. - Thank you for your work.

It's risotto.

I can put this on here.

Exactly.

- Gosh, really. - It's like a restaurant.

That's what I'm saying.

(Five stars for the look)

My mom wouldn't cook this for me.

My mom buys me food these days.

All right.

I replaced rice with oatmeal for digestion,

and this is good for overcoming fatigue...

and increasing energy and vitality.

It looks so good.

You can eat it now.

(Customized breakfast for Iron Girls is completed.)

I do love abalone.

- Thank you for the food. - Thank you.

Is it salty?

(Taking a bite with much expectation)

(Goodness)

It just tastes like...

the porridge we eat after eating shabu-shabu.

Seo Yeon, this tastes insane.

- This... - Seo Yeon.

octopus contains taurine.

So it's good for overcoming fatigue.

I can't take my eyes off Seo Yeon.

She's awesome.

Enjoy your meal.

Mom.

Mom.

I'm so jealous of your kid, Seo Yeon.

May I modify my family relation certificate?

Eat.

(Mommy Seo Yeon is chic and sweet at the same time.)

Mix chive and octopus together when you eat.

- It tastes like a restaurant. - It's seasoned just right.

It looks really good.

(Savoring reverently)

Does it taste fine with you?

(No words needed)

- It's really good. - It's a legend.

Abalone tastes so good too.

(She puts the abalone on the porridge,)

(takes a spoonful,)

(and eats it all at once.)

It's so good.

So this is what oatmeal tastes like.

No, it doesn't.

It has no taste, just like plain porridge, but Seo Yeon seasoned it.

it tastes so savory.

Perilla seed oil is very good for your health.

(Taking a bite of octopus porridge)

It tastes better, right?

(Giving a loving look)

- This is really good. - It's so good.

It's a legend. Goodness.

(Eating again and again)

- I'm done. - It's really good.

Don't finish it.

(A bolt from the blue)

If you swim later, you'll feel nauseous.

- I want to eat. - Come on.

(I can't stop eating this.)

(Ju Hyun has been eating a lot for quite a while.)

(When she went home after the training camp,)

(she cooked the dish again to eat.)

(You should try it too.)

- I enjoyed it so much. - Thank you for the food.

Thank you for the food.

We need to get going now. Let's go.

I kind of get ambitious.

- It's going to be fun. - Here.

- What's this? - I brought it.

Where's my cell phone?

I brought my cell phone with me for sure.

No way.

(Did I leave it?)

(Ju Hyun is cute.)

People say I'm high-maintenance,

but Ju Hyun makes me alert.

You should stick with me all the time.

I'll take care of you. I like doing it.

You made my heart flutter.

- I'll take care of you. - That's insane.

(Gosh, I can't do this.)

(Childish Park is whining all the time.)

(You didn't take any break, they said.)

(UIe is caring for Ju Hyun without a break.)

(High maintenance Ju Hyun)

(Help me with this!)

(Sometimes high maintenance UIe)

(Bickering)

(Exclaiming)

(Heart-fluttering chemistry)

(Send your support!)

It smells like a swimming pool.

(The second day of Iron Girls' training camp)

- I'm so nervous. - You must be...

familiar with this smell.

(The first swimming training)

(Captain Kim is waiting for them.)

(Seo Yeon appears.)

This is...

Hello, Captain.

This is what I couldn't even imagine when I was training.

- Hello. - The current time is...

I'm sorry.

How come a trainer comes earlier and waits for athletes...

Are you our trainer today?

(My mistake)

- Captain. - Nice to meet you.

Captain, right. Hello.

- By the way, Captain. - Yes.

Can I ask you one thing I'm curious about?

You're curious about so many things.

Didn't you take a shower? Why is it still there?

What's this?

You mean this? It's not erasable.

- Are you sure? - I can't erase this.

(He participated in a triathlon yesterday,)

(and it's his entry number.)

Yes, this is...

No, no.

(Startled)

A triathlon participant...

has a pride in it.

You want to keep it to the maximum.

- So you won't erase it? - Once you participate in it,

you wouldn't want to erase this.

You'd feel it later.

I really don't want to erase this.

Did you apply a hair product?

No, it's water.

I already practiced for quite a while.

(In Ah is amazed to look at Dong Hyun's hair.)

Do you have extremely curly hair?

No, I went to a beauty salon.

Extremely curly hair?

(He's like a student teacher at a girls' high school.)

- I paid for it, and they used foil. - Foil?

Yes. So...

you're here in a swimming suit.

It's the most important event of a triathlon...

and also one with a lot of cut-offs.

Training it is important,

and it's the toughest event to hold out.

For a triathlon, you swim in open water,

be it a river or a sea.

(An open-water race in a river or a sea)

You need to swim 1.5km for a triathlon.

(1.5km distance)

(With many factors such as the weather and the current,)

(many participants are eliminated.)

(If you exceed the time limit of 50 minutes,)

(you're eliminated.)

(Extreme physical strength and skill are needed...)

(in the first event, swimming.)

This is a 25m-long pool.

But a triathlon we're doing is, as you know...

- It's 1.5km. - It's 1.5km.

You need to swim here back and forth 30 times.

(30 rounds back and forth)

It's 60 times one way.

(30 rounds back and forth)

I can't imagine it.

I can instruct you,

but I pulled all the strings I have...

and brought the best coach.

- He's a social butterfly. - I mean it.

First of all, the coach coming today...

won 29 medals in the National Sports Festivals,

(The coach won 29 medals in the National Sports Festivals.)

the best player in the nation.

It's the same number as my age.

She's the best swimmer in Korea,

and you might know...

that she was a swimming commentator in the Paris Summer Games this year.

(The swimming commentator in the 2024 Paris Summer Games)

Let's bring in the coach.

- My gosh. - Goodness.

(Today's special swimming coach!)

Hello.

- It's been a long while. - This is amazing.

She's a celebrity.

- It's amazing. - You say I'm a celebrity?

The celebrities are here.

This is your coach, Jung You In.

- Hello, nice to meet you. - Please introduce yourself.

I was a national team member in Incheon Asian Games...

and a national team member in 2019 Gwangju World Championship.

I'm swimmer Jung You In.

(Former national team swimmer Jung You In)

(A leading player in Korean women's swimming)

(The one with a new Korean record in women's 400m relay swimming)

(Overwhelming swimming skill)

(29 medals in the National Sports Festivals!)

(People call her female Ma Dong Seok due to her natural-born muscles.)

(Born with muscles)

(Former national team swimmer Jung You In)

(Open-mouthed)

- It's nice to meet you. - Ma'am.

Nice to meet you.

- This is amazing. - Nice to meet you.

- It's amazing. - It's been a while.

I got goosebumps.

- I'm honored. - No, I'm honored.

- Goodness. - She's so awesome.

First of all,

you have a great build.

Does having muscular strength help your swimming?

Yes, muscular strength helps.

Especially for swimming, when your upper body is muscular,

it gives you much more advantage.

(Showing off her upper body muscles)

- What do you think? - That's nice.

- You're straining this part. - You look nice.

- You're straining here. - Here?

Yes, you're straining here.

You're straining muscles on your chin.

It hurts.

What if you're...

- She's afraid of water. - In that case,

what do you need to start first?

You need to get familiar with water first.

But I have a severe trauma about water.

Once the water level gets higher than this,

my body becomes stiff, and I can't breathe.

Can you tell us why...

- you got the trauma? - When I was little,

I almost died in a public bath.

I see.

Although it was shallow water, I slipped...

In fact, falling in the water...

- has nothing to do with the depth. - It doesn't.

Yes. When your body is tense...

and you breathe out air and inhale water,

you get to sink.

Still, Seo Yeon...

May I call you a player?

Player Seo Yeon...

May I call you a player? Player Seo Yeon...

(We're players?)

- Yes, of course. - Yes.

Still, it's fortunate that Player Seo Yeon...

can go into the water this much.

Those who have a really serious fear of water...

get goosebumps even looking at the water...

and can't put their feet into it either.

I hope you can utilize this chance...

to learn how to swim.

First, we need to check your swimming skills.

- Shall we start swimming? - Yes.

- Yes. - All right.

The coach doesn't know your swimming skills,

so she'll see how each of you swim.

- But... - Yes.

is it okay that we see her swim just once?

The real swimming.

(Me first?)

They're so suspicious.

I guess you're not doubting her skills.

We doubt you, but we want to see her swim as a fan.

You're doubting me. I see.

- To look at her swim... - To see her swim,

- we need to stand up. - That's right.

Let's see her swim here.

I can't believe this.

Then I'll show you not the fast swimming,

- but the comfortable one. - All right.

- I'll do it like a warm-up. - Okay.

- Let's see. - Let's see,

(Excited)

(The national team member looks charismatic when preparing.)

(It's time to see a national team member's swimming...)

(in person.)

(It's time to see a national team member's swimming...)

(in person.)

She's diving.

(While everyone watching in silence)

She has moved half of the distance.

She's already there.

She's awesome.

(Like an energetic dolphin)

(Gentle waves)

(Time to see swimming)

- She's moving smoothly. - Her moves are so smooth.

(Coach, we can feel...)

(that your swimming is perfect.)

Seriously.

Right after she dived in, she moved ahead so much.

(Turning in the water)

What was that?

(Is that possible?)

(She makes a turn in the water and switches direction easily.)

- She's already there. - What? Where has she gone?

Excuse me.

(Where has our coach gone?)

- Where is she? - Over there.

She's there.

Goodness.

(She moved this much already by underwater swimming.)

(While disappearing)

(Is she flying?)

Look at that!

You In!

(Swimming in the water,)

(she moves her arms like a butterfly.)

She's so awesome.

(So smooth)

She's so awesome.

(You can feel her power just watching her swimming.)

(She comes back in an instant.)

(Her demonstration is over.)

Beautiful.

- Gosh. - My goodness.

Her butterfly stroke looks amazing.

- I know, right? - The butterfly was the best.

- Now, each of you will swim. - Okay.

(Before entering water,)

(she puts water on her body.)

It's cold.

Go now.

- Are you ready? - Gosh, it's cold.

You'll feel hot when you come back.

I guarantee you'll feel hot when you come back.

Let's see how you swim. Just do it comfortably.

- Okay. - You can do it.

Go for it!

I'm afraid of cold water.

It's fine if you come back quickly.

(What? Cold water?)

Ju Hyun said she's afraid of cold water.

Ju Hyun, you don't need to hurry.

Ju Hyun, you don't need to hurry.

(Laughing)

- Take your time. - Take your time.

She really looks scared. Are you serious?

It feels like a shark might appear.

- There's no shark. - Shark?

I know there's none, but...

That's understandable.

One more time. Do it longer this time.

(As expected of Childish Park)

There you go.

In 1, 2, 3.

Good. Good job.

You can do it, Ju Hyun!

(She overcame the fear of cold water.)

Are you ready?

Ready, set,

go!

(A nice start!)

(It wasn't bad...)

She looks like she's snorkeling.

(Under the water as if she's looking at fish in the sea)

(By the way)

When is she breathing?

- She's not breathing. - Breathe!

- She's not breathing. - It's been ten seconds.

- Good. - She's breathing now.

- She's swimming breaststroke. - It was breaststroke.

(It kind of looks like breaststroke,)

(but it might be underwater swimming.)

Breathe!

- Is that okay? - She's not breathing enough.

She's moving ahead.

Usually, newbie swimmers feel more comfortable when not breathing.

She's holding her breath for quite a long while.

She's holding her breath for a long time.

(Ju Hyun holds her breath for so long that others worry about her.)

(Inhaling)

(She inhaled only a tiny amount of air.)

(Her swimming isn't a butterfly or underwater swimming.)

(She manages to get to the turning point.)

(This is killing me.)

(Show me your freestyle.)

- Okay, freestyle. - Freestyle.

(She makes a turn and switches to freestyle.)

She's coming.

- She's not breathing. - She's not.

I don't know how.

"I don't know how."

She's able to say that.

- That's good. - Good.

I can't do it anymore.

- Don't do it. - Okay.

- Do it as much as you can. - Finish it.

Do it as much as you can.

(Only her head above water?)

What kind of swimming is that?

It's called Boktteong Paddle,

one done by dogs.

- Dog paddle. - Boktteong Paddle?

(Ju Hyun's swimming looks similar to her dog Boktteong's swimming.)

- She's so confident. - She's getting close, though.

She's finishing it.

Right.

(Her swimming is almost the same as Boktteong's swimming.)

To the end!

To the end!

This is too long.

She finished it.

- You did it. - Your breaststroke is good.

I feel like vomiting.

Did you learn breaststroke only?

- You didn't take a lesson? - I didn't learn it.

It's like swimming in the sea...

- Right. - or swimming in a hotel pool.

I'm from Busan.

So it's just Haeundae-style swimming.

The survival swimming. Haeundae-style swimming.

She moved quite all right using her hands and feet like this.

- She kept doing it. - Dog paddle.

(Reenacting Boktteong's swimming)

I guess with that,

it took 52 seconds to the turning point and 55 seconds coming back.

- It's a cut-off. - Yes. It's 1 minute and 47 seconds.

If she learns freestyle...

As freestyle is the fast one,

if you learn it,

you'll make a much faster record than now.

(Ju Hyun's 50m record: 1 minute 47 seconds)

(Swimming for hotel vacation)

(She doesn't know the breathing method.)

(She tries to come out of the water...)

(but fails as her arms feel rubbery.)

- Moving 50m... - My arms.

- It took 52 seconds to go there... - Really?

You want to come out, but you can't, right?

I'd like to help you.

(I'd like to help you.)

Let me help you.

(For Ju Hyun who can't come out of the water)

It's okay, right? Step on here.

So sweet.

(Captain...)

(So sweet)

(With Captain's help)

Step on his knee.

She grabbed my head.

(As expected of Childish Park)

I didn't tell you to grab my head.

My head... Okay.

She grabbed my head.

- That was cute. - She grabbed my head.

Hey.

- I'm fine. - It's In Ah's turn.

I'm fine.

The current record is 52 seconds going to the turning point...

and 55 seconds coming back.

(Moving her feet)

- But I... - For 50 m...

swam in elementary school, and haven't done it since then.

I will have hope that you have an experience.

She's a Sports Genius.

- No, I'm not. - She really is.

- Are you ready? - Yes.

Ready, set, go!

Her move is so smooth.

She's going smoothly. Good.

She's good.

Come on.

- Come on. - Her swimming is good.

- Hasn't she learned swimming? - Give her a hand.

- Hasn't she learned at all? - She did until elementary.

(In Ah is a Sports Genius as always.)

(As if she's racing in the water,)

(In Ah moves ahead fast.)

- No way. - Her body remembers.

She's amazing.

If you learn to swim in elementary school,

you'll still be good at it even after 20 years.

In Ah is amazing.

She's been lying to us. She's good at everything.

She's so fast.

(After touching the turning point,)

(she swims again.)

(She swims a great speed.)

She's a Sports Genius.

She's good at everything.

Seriously.

(Her awesomeness is exploding.)

If she eases up a bit, swims slowly,

and adjusts her kicking posture,

she'll be good to go.

- Her arms... - She's a good swimmer.

- She's grabbing the water. - Yes.

(This is how the Sports Genius swims.)

She's amazing.

- You're good. - Amazing!

(In Ah finishes.)

(As soon as she's done, everyone starts clapping.)

- It's amazing. - I timed her.

- She's very fast. - How long did she take?

- She's very fast. - How long did she take?

- 23.92 seconds going out. - Yes.

28.61 seconds coming in.

(Total: 52.53 seconds)

- She swam fast. - Yes.

She needs to learn how to pace...

while mastering long-distance swimming techniques. She did good.

- Please give a round of applause. - This speed is like 100 seconds.

- Her kick is good. - I knew it.

She's amazing.

(Her pace is too fast.)

- She's amazing. - Next is UIe.

- UIe, you can do 100m. - No, thank you.

Show us butterfly, backstroke,

- breaststroke, and freestyle. - No!

- She was a real athlete. - Let me just do it normally.

It'll be so cool.

You can do a bit of butterfly while you come back.

- We won't stop you. - Maybe twice?

No, I don't want to.

Maybe later.

- Are you going to start from here? - Yes.

- Diving! - Diving?

(She'll dive into the water.)

I'll start.

Go!

(She dives into the water without hesitation.)

(Creating a splash behind her,)

(Ace UIe swims through the water.)

- The dolphin kick. - When is she coming out?

She's good.

When is she coming out?

(My goodness)

(After diving in, she has already covered...)

(one-third of the distance using only dolphin kicks.)

(With her long arms and legs, she moves smoothly forward)

Her form is very pretty.

She's our ace.

- She breathes regularly. - Her arms are so long.

(Everyone's amazed with her swimming posture.)

(She's especially in love.)

- It's so pretty. - A master...

- doesn’t lift their head much. - Yes.

We can't tell if they're breathing or not.

(Elegant breathing as a mermaid under the sea)

(Her posture is pretty,)

(and her speed is very fast.)

(After entering the water,)

(she reached the turning point...)

(within a few dozen seconds.)

(The underwater turn that only masters can do.)

(She's amazing.)

- She turned! - She's like a dolphin.

Her head... When she breathes,

- her mouth is barely visible. - Yes.

She breathes out naturally.

- She breathes slowly. - She's so good.

(Today, UIe shows her true skills.)

(She suddenly changes her posture.)

Let's go!

(She's definitely our ace!)

(Butterfly)

(What exactly can’t you do?)

- My goodness. - She's so cool!

(It's even better underwater.)

(She swung her arms for a few times,)

(and she arrived.)

- My goodness. - You're so cool!

Our ace!

Our ace!

Your body remembers!

- UIe! - My goodness.

(You're amazing!)

- No, her body remembers. - What was that?

You swam like an athlete.

It was so impressive...

when she switched from freestyle to butterfly.

(Today's highlight selected by Ju Hyun)

I think we need to change our captain.

Swimming... No!

- For swimming, yes. You're right. - I'm right.

It was 20.68 seconds going out,

but coming in, you slowed down during butterfly.

It was 23.30 seconds coming in.

So it's around 43 seconds.

It's so fast.

She's too good.

Your body is gorgeous.

- Her arms... - It was too pretty.

(How did I do?)

- Your strokes were very pretty. - For real.

- Her arms are long. - Mine are long,

but they're thick so they don't look long.

But yours are very beautiful.

It's important to have a gorgeous posture,

and you didn't splash a lot of water.

It felt more like she was handling the water...

than fighting against it.

Right now, you’re panting heavily.

UIe needs to focus on...

reducing her kick...

and adapting swimming techniques for long-distance.

You can have the same records with easier swimming.

(UIe's 50m record: 44.38 seconds)

(Her kicks were too fast.)

(She needs to reduce her kicks for long-distance swimming.)

Lastly...

(The last person to try is...)

She has a trauma, but she can try.

Can you go in the water?

Can you show us?

- Try it. - I'll try to go in.

- You can do it. - You can do it!

- How deep is the water? - She's awesome.

- Look. - Seo Yeon,

- should she be next to you? - It's until here.

It's until here.

For me, it's until here.

It's too deep.

(It's her first time to enter the water without any devices.)

- How is it? - It's deep.

Is it? But she looks more relaxed than I thought.

- She can do it. - Yes.

She looks relaxed.

(Quick steps)

(She's busy underwater unlike how she is above.)

Coach.

They ask me about swimming.

When entering the water, shall we breathe out using our nose?

Or our mouth?

For breathing,

we'll use our noses to breathe out inside the water.

Above the water, we'll breathe in using our mouths.

(Breathe out using the nose)

(Breath in using the mouth)

(Breathe out using the nose)

(Breath in using the mouth)

I'll show you.

Using your nose...

(Breathe out)

(Breathe in)

(Breathe out)

(Breathe in)

(Breathing in and out)

(Master version of breathing in and out)

(Seo Yeon is so nervous.)

(She gathers her courage and puts her face in the water.)

(Gasps)

Good.

I had hyperventilation.

(Worried)

Take it easy.

(She tries again right after.)

(Gasps)

You breathed in too much.

Don't breathe out too much.

Also, not too much in.

Breathe only 30 percent of your usual rate.

(They learn how to breathe properly inside the water.)

Breathe normally.

Very good.

Let's try to put our eyes in.

Let's try putting it in. Good.

Slowly and deeply.

Short and quick.

(In Ah and Ju Hyun can go deeper.)

Short and quick.

(Is Seo Yeon trying to go fully underwater?)

(She experiences hyperventilation immediately due to nervousness.)

It's okay.

(Worried)

For Seo Yeon,

it's important to practice breathing...

and get closer to the water.

There is a place where the water is shallower.

Let's practice breathing there.

The three of you...

will focus on leveling up.

Freestyle swimming...

- Is it? - and posture correction.

(Pre-beginner class: Jin Seo Yeon)

(Beginner class: Park Ju Hyun)

(Advanced class: Seol In Ah and UIe)

(Pre-beginner class: Jin Seo Yeon)

(With Captain Kim)

Breathing is the most important part of swimming.

Breathe out inside the water and breathe in outside.

(She's so nervous.)

(She practices slowly.)

Good.

(Gasps)

Okay. It's okay.

You're doing well.

If you're okay, don't put your head all the way down.

(Putting the face in the water as if you're washing your face)

Maybe this would be better.

(She tries to follow slowly.)

Good.

(My goodness)

You don't need to raise your head too high.

We don't raise it that high while swimming.

Your head... Look.

You don't need to raise your head too high.

If you raise it too high, water enters your mouth.

Do like this instead.

- This is easier. - I'll try.

Yes. Okay!

This is better. Okay!

This is far better.

It prevents water from entering your mouth.

- Shall I go further down? - If you can, yes.

(Breathing out heavily)

You're doing good.

(She is diving into the water more confidently.)

(Iron Mentality tries until the impossible becomes possible.)

You're doing too well. Three,

(While Seo Yeon is getting used to the water...)

Four.

(While Seo Yeon is getting used to the water...)

(Beginner class: Park Ju Hyun)

(With Coach Jung You In)

(She's not used to wearing a swimming cap.)

I...

If I explain only using words, it's difficult to understand.

We'll record a video and watch it together.

Let's review and work on it.

Ready, go.

(She starts by freestyle swimming without any coaching.)

(The coach is analyzing her posture.)

(She swims with her Busan instinct.)

(She did finish until the end.)

Okay, good.

Is this freestyle swimming?

Yes, it is.

You seem to be a real fighter who never gives up.

You couldn't breathe but came all the way here.

- You just drank water. - Yes.

(Did she come here without breathing?)

(Breathing out)

(Breathing in)

(She didn't know when to breathe, so she just held her breath.)

You'll know when you see yourself.

(How is her posture?)

Your head is lifted too high, causing your legs to sink.

(Her head is lifted too high, causing her legs to sink.)

You're facing the front.

- Your chin is stretched upward. - Yes.

That's why your legs are sinking.

You need to tuck your chin and submerge your head in the water.

If you don't, you will sink.

And when you breathe, you sink a lot.

Grab this and kick.

We'll use only one arm to swim.

One. Breathe.

(Press your ears tightly against your arms and take a breath.)

Yes, that's right. Two.

(Put the head in the water and breathe out.)

One, two.

(Awkward)

Put on your goggles.

(She's determined.)

- Athlete Park Ju Hyun. - Go.

Ready, go!

Put your head in.

One,

breathe, two.

One.

Two.

Put your head in. Good.

(While Ju Hyun was getting an official training...)

(Advanced class: Seol In Ah and UIe)

(UIe, being an advanced swimmer)

Reduce your kicks.

Practice long-distance suited swimming.

(She swam one lap alone.)

I think I can swim 1,500m with this technique.

This swimming technique opened a new world for me.

(She quickly mastered the technique of swimming with minimal effort.)

Did you get it?

Watch me.

If I swim fast... Look.

(Splashing)

If I swim like this,

If I swim like this,

(She was observing in the water.)

I'll definitely get tired. But as the coach said...

(She demonstrates swimming with minimal effort.)

(In Ah tries the same technique listening to her advice.)

(By relaxing as much as possible, there's not much splashes)

How was it?

(Thumbs up)

When you breathe,

spread your arm and make sure your ear touches your arm.

You need to...

stretch out and stay streamlined.

(When her ear touches her shoulder, her body floats in a straight line.)

If you don't, your body sinks.

- I see. - How was it?

- There is tension in my neck. - Your neck?

I'm curious about something.

When we were freestyle swimming a few days ago...

(Ju Hyun is immersed in intense water play alone.)

(Hanging)

- Do I need to see the floor? - After touching it slightly...

But now, I want to ask you a favor.

- Yes. - Yes.

Ju Hyun here has been practicing...

- the breathing techniques. - Okay.

I think you'll be great at coaching.

Make sure her head is in the water.

- Please monitor her. - Where are you going?

- There. She's doing kicks now. - She's going to see Seo Yeon.

My goodness. Kicks?

- So I'll coach her kicks. - Okay.

You're swimming so well.

(She's even good at it.)

You're good because you have muscles.

You're going fast.

(Breathing is difficult, but her kicks are awesome.)

- Later on... - Are you used to water already?

Coach! I taught her!

- Show her your kicks. - Yes.

What did you do? Did you learn to kick?

I just showed her.

Don't be nervous.

(Moving forward)

Her kicks are good!

- She's good, right? - Yes.

She goes to the gym, so she has muscles.

(She looks peaceful unlike how she was a while ago.)

Why are you so good?

You're good at all sports.

She did weight training for a long time.

We can move on to the next step of putting your head in the water.

Here.

(Great progress for a complete beginner class)

(Breathing underwater and kicking while holding onto the board)

(She isn't confident.)

(Try doing it the way I showed you earlier.)

That's good.

Okay.

(Will Seo Yeon master breathing and kicking today?)

Don't follow along. Close your mouth.

- While we swim... - I'll swim one lap.

Yes. We push...

Because our arms are not coordinating,

the next arm has to come back when the other is pushing.

I'll try.

(She's swimming forward.)

Ju Hyun!

(Senior UIe suddenly swims to her in a hurry.)

Ju Hyun!

Your goggles!

(She's immersed so she can't hear anything.)

Ju Hyun, you have to wear your goggles.

- Oh, yes. - You should wear your goggles.

(After confidently declaring that she would swim one lap alone,)

(she went ahead without goggles.)

(She closed her eyes in the water.)

When we focus on one thing, others are forgotten.

I was so surprised.

You were swimming with your goggles on your head.

- Stop it. - I was like, "Ju Hyun!"

What was more comfortable?

(Starting from the basics one by one with UIe's help)

(Sports Genius In Ah swims nonstop.)

(The first swimming lesson to complete the triathlon.)

(Final check of the first swimming training)

To wrap up today’s class,

- we will... - To wrap up...

swim one lap implementing what we learned today.

- Let's see how much we've improved. - Let's observe and talk about it.

- Yes, UIe. - You can do it.

- You can do it. - Go!

Go!

(How has her technique changed after the first training session?)

(Senior UIe moves forward smoothly and effortlessly.)

- My goodness. - She's good.

And again!

(Senior UIe moves forward smoothly and effortlessly.)

(She was so tense that water was splashing everywhere before.)

(Now, the water is almost still with barely any splashes)

It's amazing.

(Amazed)

My goodness.

People who swim well keep their heads nearly submerged.

She lifts her head just for a second.

(UIe's swimming is like an advanced senior's swim.)

But UIe has something to learn from me.

(Iron Senior keeps an eye on Senior UIe.)

No.

(She returns in a perfect posture.)

I'm jealous.

- Seriously. She's so cool. - How was it?

It's not tiring when I swim in this technique.

Aren't you tired?

UIe, sorry, but you have something to learn from me.

- You can learn one thing from me. - What is it?

You take a breath every fourth stroke, but in a triathlon...

(UIe has a habit of holding her breath for a long time.)

It's difficult to do that in the triathlon.

I'll train you on breathing every stroke.

He's right.

- In Ah, you can swim from here. - Go!

- Okay. - Go!

(Sports Genius swims forward without hesitation.)

My goodness.

(Amazed again)

- It's different from before. - Yes.

Her head isn't lifted as much.

(Her skills are on par with UIe's.)

She's very good.

(Before training)

(Her head was lifted, causing her body to sink.)

(After training)

(Her ear is touching her shoulder to keep her arms from dropping.)

(Relaxed arm stroke that looks comfortable even from a distance)

She's so good.

- My goodness. - Oh, my.

- I mean... - My goodness.

- It's so good. - Did I improve?

- Of course. - Gosh.

Ju Hyun, get ready.

She learned freestyle swimming for the first time today.

- It was her first lesson? - My gosh.

(She tries without the kickboard.)

I'm amazed that she's moving forward.

Is she swimming forward?

(She swims forward without stopping.)

- She's advanced. - She improved a lot.

(She can swim freestyle!)

(Her posture isn't perfect yet,)

You can do it!

(but she still makes it until the end.)

(She's surely resilient.)

(She even returns to the starting point without a break.)

- How can she do that? - She's beyond our expectations.

- I can't believe it. - She's even coming back.

(Other members are also shocked by her resilience.)

(She never stops nor takes a rest when coming back.)

She is doing so well.

She didn't even stand up with her two feet all the way.

(She finished a lap with freestyle.)

- She's amazing! - You're so cool, Ju Hyun!

You're awesome, Park Ju Hyun!

(She finally takes a breath out of the pool.)

You did a 50m lap successfully.

You had difficulty having a 10m lap before.

But it was hard to breathe during the swim.

- I can't believe her skill. - That's natural.

It'd be even strange if you could breathe in comfort.

So, don't worry. It's so natural.

No one can be good at it at this stage.

It's her first day...

learning how to swim.

By the way,

why are you staying in the pool for so long?

- She's doing well. - I feel good now.

That's good news!

- She's getting better. - But what are we doing now?

Let's grab a swimming float and continue practicing.

That's what we learned at the end of the training.

- If she can do it, that'd be cool. - Can she really do that?

- Yes, I practiced. - Really?

- Congratulations! - Ready.

Set, go!

Go!

Just try it!

Be relaxed!

Don't be nervous.

You can do it!

You got this.

- Seriously? - Gosh!

I can't believe it!

- And she's very fast. - Yes, she is.

She has good muscle strength!

Yes, that's why she's doing so well.

- Seo Yeon! - Keep moving your feet!

(Thanks to her 15 years of weight training,)

(she moves her feet very well.)

(She can now breathe comfortably while swimming.)

Kick!

(She finally arrives at the end of the lap without a break.)

- You did a good job! - Take a breath before going back.

Nice!

Let's go!

- You got this! - You can do it!

- Let's go! - You can do it!

Go!

(After shouting,)

You got this!

(she starts swimming again to the beginning point.)

You're doing well!

Just a little more!

- As Captain Kim taught you! - Let's go!

- You're doing well! - It's not so far!

As I taught you!

- Slowly! - It's good!

Keep moving your feet!

I can't believe she did a 50m lap.

(She's heading to the starting point using her muscle power.)

- Oh, my! - Keep moving!

She's doing so well!

You're almost there.

- You got this. - You're doing so well.

- It's okay. - Let's give her an applause.

Good. You did so well.

(Every member finished the first swim so well.)

- You're so cool! - Amazing!

(They hug each other feeling impressed.)

It was a 50m lap,

and all were touched.

Then, I can't imagine what'll happen when we conquer the triathlon.

- We didn't know he was there. - I'm coming too.

- Let's go! - We can do it!

Let's go!

- We got this! - We will make it!

Nice!

(The swimming class has ended.)

(The first camp training is over.)

(Now it's time for individual training.)

(How will Iron Girls spend the next 3 weeks?)

(Exercise)

(A training app for Iron Girls)

(Each receives training homework through the app.)

(Midday exercise: Basic running, cadence breathing for 90 minutes)

(40 minutes running, 40 minutes interval running,)

(20 minutes jogging, 3 minutes break, 20 minutes jogging)

(40 minutes running: Due to the knee injury,)

(I finished at a slow pace. Get well, my knees!)

I'm visiting my sister in Incheon,

and I heard there was a track I could run,

so I will run for 40 minutes today.

Let's go!

(Her running training has started.)

(Her sister is filming UIe.)

Your pace is getting better.

(Your pace is getting better.)

(I need to train to run more often.)

(I feel I'm getting better, but my knees still hurt.)

(I told the gym center...)

(I would finish in 3 months and come back.)

(So I must do this.)

(Today's homework, 40 minutes running has been finished.)

- I guess 700m is left. - Oh, yes. You almost got this.

Both swimming and running are the hardest.

- You think so? - Yes.

(Do you think so?)

(But she always feels the training is not enough.)

(Panting)

(Panting)

(She's too fast to follow.)

(In the meantime, she's already coming back.)

(She's surely an ace.)

Hello!

After four days of workouts,

I took the InBody Test.

My muscle has increased by 1kg,

and my body fat has decreased by 2kg.

Just in four days!

(Just in 4 days of personal training)

Can you imagine how hard it was?

(Ju Hyun is doing her best to be the Iron Girl.)

You should push it until the end.

(Today's homework, 1-hour swimming has been finished.)

Now I'm on an overseas business trip.

I got some time to take a break,

so I ran to the swimming pool.

I'll practice the freestyle!

Let's go!

(With her swimming tools,)

(she starts practicing, especially arm and foot movement.)

(Today's homework, 40 minutes of freestyle has been finished.)

(She even trains on an overseas business trip.)

Swimming in the sea is done!

(She feels shy after saying it.)

(I practiced until I felt I might die if I trained like this.)

(My schedule is too tight,)

(but I'm trying to squeeze it.)

(Ju Hyun is truly a dogged spirit.)

I finished...

the triathlon!

(Seo Yeon's training routine in Jeju)

(Today's homework, Mount Halla trail running has been finished.)

(Today's homework, running for 1 hour at dawn has been finished.)

Quickly!

You're at the right pace.

(My face looks so tired now. Yesterday was so hard.)

(The training will be harder, but I need to keep track of it.)

(I feel so tired every day.)

(Her shirt is full of sweat.)

How do you feel now?

I feel like I'm dying soon.

Go in.

(But swimming is even harder.)

(She gets special training as she fears water.)

(I swam for 30 minutes in a row.)

(Now I feel confident.)

(Swimming is still hard.)

(Sometimes, I can breathe well, but my body gets stiff.)

(It continues again and again.)

Okay.

(She pushes herself to the end.)

(Her mentality is also the Iron Girl.)

(Sighing)

Running training in the evening is complete.

I pushed myself to the end,

but only 45 seconds diminished.

I can't even say a word.

(In Ah focuses on running as she feels weak on it.)

Draw your jaw and down your chest.

That's it.

Just a little more!

(This drives me crazy!)

(After doing all this,)

(I felt I was no good at aerobic exercise.)

(Her shirt full of sweat tells us everything about how hard it was.)

My pelvis hurts so much!

Continue!

(He's so strict.)

(Iron Girls had a busy July.)

In one.

- All right. - This is not the end!

We will continue after this.

- One, two, three. - It's so hard.

One more. We should do one more set.

- Just one more. - Three!

Five, six, seven, eight, nine, and ten!

(Exhausted)

Your thigh hurts?

I'm just tired.

(No, I'm just tired.)

Left arm!

Don't move your arms too much. Keep them close.

- Like this. - I see.

- I got what you mean. - Yes, that's it.

Embrace your arms and then run.

(Ju Hyun is also busy correcting her position.)

Yes. The shoulder rotation should help you.

Yes, you should run like that.

Feel how the rotational force helps you.

Now we begin moving arms.

Running should be simple.

Simple!

(Today's homework, special running training has been finished.)

Draw your chin.

As we did before, push it.

Even if the position is somewhat distracted, it gets better.

Nice.

(Seo Yeon keeps running following the couch's training.)

You became much better than before.

(Iron Girls trained for the whole month of July.)

(3 weeks later)

- Let's see. - Oh, my!

- This way! - Finally, we're here.

Take a look.

Who's the Captain here?

- Kim Dong Hyun! - Yes!

When you participate in an actual competition,

the shoes should fit you well.

What's this?

- I really wanted to try this. - Me too.

- Ju Hyun, you got slim feet? - It looks cool.

Yes.

- She does indeed! - She got slim feet.

This machine is really cool.

(The exact shape of the feet comes out through the scan.)

Even it shows the size!

It recommends the best shoes?

It's really cool.

It's actually the hardest part.

I've used shoes from here, so I can tell they are soft.

- These are really light! - Really?

- These look good on you. - These are so pretty!

I've heard there's an event...

- for people running. - Oh, yes. There is.

It's called the "Run Club."

It's actually not fun to run alone...

- and hard to continue. - Yes, that's right.

- When in a club, you can run more. - Right.

- Let's run together someday. - That's good.

- Nice. - Yes.

It's pretty.

(All sports begin with good equipment.)

What kind of mission is waiting for us? I can't easily buy anything.

I don't think they will allow us to go home without a mission.

That makes me scary.

After all these presents,

they won't let us go home easily.

What's going on?

(Jamsil Tower)

It's so scary.

Come over here!

Hey!

My cute UIe!

Are you already warming up?

- I should. - Let's do.

I don't know what's coming, but...

The tower is so big as I see from this side.

Captain Kim,

- what's the matter? - Sorry?

What should we do?

It's not just a mall.

- It's related... - Then?

to the triathlon.

- You mean here? - Yes.

I don't see any of it.

This is the course of the competition...

hosted by the Korea Triathlon Federation.

Here? What will we do here?

(In the middle of the city of Seoul,)

(Jamsil Tower stands tall.)

(An Iron Person was born here?)

An aquathlon competition was held here.

There was a 1.5km swim in the Seokchon Lake.

(A 1.5km swim in Seokchon Lake)

(It's the marathon after the swim.)

The marathon came next after that.

It wasn't a horizontal marathon but a vertical marathon.

(How was the marathon done vertically?)

(The tallest place in Korea)

(Reach the sky!)

It's a total of 123 floors until the top.

It's 555m high and there are around 2,900 steps.

(Hold on.)

(Does that mean our training is...)

You can see it, right? It's a vertical marathon...

until the top of this building.

(Screaming)

I think I've seen an article of this before.

- Gosh! - I sent a message on this, right?

- What? - Yes.

(A message that Ju Hyun sent in the group chat one day)

(Iron Girls)

(The duathlon looks amazing too.)

(The news footage that Ju Hyun happened to catch)

(A 1.5km swim in Seokchon Lake and a 123-floor climb)

Gosh, that's insane.

(This was none of her business at this moment.)

- Did you make us do this? - You wanted to do it?

- I happened to watch this. - That must be right.

We were thinking about what course to choose,

but Ju Hyun sent us that message.

We loved the idea, so we went to this place.

- Are you serious? - Why did you send it?

Are you insane?

- That is why we're here. - But...

I've never gone up 5 floors on the stairs.

- On stairs? - I haven't.

But isn't that building famous...

for going up 123 floors on the elevator?

There's a reason for climbing stairs.

We're not just trying to make you suffer.

Climbing stairs is good for your heart and lungs.

It improves your muscular strength...

and your stamina as well.

For athletes,

climbing stairs or hills are the best way to gain stamina.

My heart hurts whenever I come to this shoot.

Try looking up at it.

- It hurts your neck. - It really hurts your neck.

Did you take a look?

(Worried)

Right.

The best female record...

is 23 minutes and 18 seconds.

Those athletes have been training for a long time.

They put in a lot of effort.

But the average record...

is 40 minutes.

So we will aim to climb up in 40 minutes.

Will it be possible for us?

If you don't make it up there in 40 minutes...

- Will you take away our clothes? - A penalty?

- I'll just give them to you. - You'll take them away, right?

I expected this to happen,

so I cut up the price tags and threw them away.

Are you holding the price tag?

It was in my pants.

(I was just making sure.)

This will test your mentality.

You have to train your mentality.

If you reach the top,

it will be an amazing memory and mentality boost.

You'll tell this to anyone that passes by this building.

"I went up that building."

- I do admit that. - Seriously.

Right.

We can just go for it. We can do it.

- We almost failed that time. - Iron!

Did you come up with a team chant? What is it?

We'll call out, "Iron!"

- And you call out, "Girls!" - And we end with, "Go!"

- Okay. - Okay. Let's go.

- Iron! - Girls!

- Go! - Go!

Let's go!

- Let's not get hurt. - Right.

(They get their taping done to avoid injuries.)

(They stretch thoroughly too.)

(What's waiting for the Iron Girls that are done with getting ready?)

(123 floors above ground level, 555m high)

(The 5th tallest building in the world.)

(From Floor 1...)

(to Floor 123)

(There are around 3,000 steps.)

(A challenge for Korea's tallest stairway to the paradise)

(Three floors must be climbed in a minute...)

It won't be easy.

(to reach the top in 40 minutes.)

(Will they able to finish the race in less than 40 minutes?)

Once you go in through that door,

you won't be able to stop.

(Time limit: 40 minutes)

I feel so nervous!

(There's tension before their challenge.)

What do I do? I feel so nervous all of a sudden.

Me too!

All right.

Let's go.

- Just start like this? - Okay. Let's go.

We'll be back.

(The goal is only the top!)

(The must reach the top in 40 minutes.)

Here we go.

- Hold on. - Okay.

- Use all of my feet. - We have to stick together.

(UIe, Ju Hyun, In Ah)

Gosh, it's humid in here.

(It took 10 seconds until the 2nd floor!)

You're moving at a great pace, Seo Yeon.

Okay.

You can't fall behind.

You can go past me if I'm too slow, Captain Kim.

I can't do that.

Gosh, my thighs...

I'm so worried about them.

If your thighs are feeling tight, use your heels to climb up.

Push your hips out and climb up with your heels.

You'll feel the back side of your thighs then.

- Both sides are feeling tight. - Both sides?

What do I do?

Then you have to use the handrail. Pull it as you go up.

I can just ignore it.

- Let's not look at it. - You're going at a fast pace.

Don't look forward.

(I can just ignore it. Don't look forward!)

(I can do it!)

(She is moving up like iron with a bright face.)

- Are you okay? - Yes.

(She even feels relaxed enough to take care of the camera team.)

(After walking for a while in silence...)

Is it okay not to talk in a variety show like this?

(A sudden doubt)

You'll reach the top with me, right?

You'll reach the top with me, right?

(The cameramen will be switched from time to time.)

- Let's do this! - Let's do this!

(They have already reached the 10th floor.)

Gosh, that makes me lose my strength!

Seriously!

- My gosh! - I won't even look at it.

(When you reach the 10th floor,)

(you will encounter Captain Kim's surprise gift.)

("People are strong. They will get done with anything.")

("Your mentality will get strong with a sense of accomplishment.")

(Mental Kim's sayings about mentality?)

What is that?

"People are strong. They will get done with anything."

"They will get done with anything." Got it?

"People are strong" Got it?

I said those things?

(Did I say those things?)

(Current location of the Iron Girls)

(The 11th floor)

(They are still doing fine as of right now.)

I live on the 18th floor.

The elevator was broken down, so I climbed up the stairs.

I guess that helped.

It feels like I'll be okay until the 18th floor.

I wish I could feel like this until the 100th floor.

(I wish I could feel like this until the 100th floor.)

- Good luck! - Good luck!

- Great! Good luck! - Good luck!

We're strong.

(Groaning)

My calves feel so tight.

Good luck!

(Groaning)

I think I'll get another cramp.

You can't do that.

(She even tries to walk on all fours.)

(Fortunately, she came back to herself quickly.)

Gosh, my calves.

They're feeling tight already.

Good luck, Ju Hyun!

Good luck. Keep yourself together!

We're on the 20th floor.

The 20th floor.

(The older ones have passed the 20th floor first.)

It's the 20th floor.

You're going at a great pace right now.

Gosh, Seol In Ah.

You're pulling up each thigh one by one.

I gave up.

(The four Iron Girls are going up at the same time.)

There's water.

(They arrive at the first drinking spot at the 22nd floor.)

(They feel glad to recharge with water.)

(Scalp shower)

All right. Get some water.

(The younger ones also move right after getting some water.)

(They move again just like from the start.)

(The pace is stable for everyone for now.)

Great. The pace is great right now.

- Let's go! - Let's go!

Let's go!

(Wise saying to celebrate the visit to the 30th floor)

"It's negativity that's left if there's no positivity!"

"Enjoy the crisis with the power of positivity!"

Okay!

What? We've already done one-fourth of the challenge.

Nice!

Let's just do three more sets.

- Let's go! - Let's just do three more sets.

Let's just do three more sets!

Let's go!

(10 minutes have passed in the vertical marathon.)

(At that moment...)

- I'll move forward, Seo Yeon. - Let's go!

(UIe moves forward.)

- Go according to your pace. - Okay.

(She takes her place which is 1st place.)

(Current rank)

(UIe in 1st place)

(Seo Yeon in 2nd place)

(Ju Hyun in 3rd place)

(In Ah in 4th place)

(Ju Hyun looks a bit exhausted in 3rd place.)

Good luck, Ju Hyun!

Good luck!

You can move ahead if you can, In Ah.

You can move ahead...

- if it's possible with you, In Ah. - Okay.

Okay. She's passing her.

(In Ah goes ahead of Ju Hyun too right away!)

Seol In Ah is pushing forward from behind!

- Go! - Gosh!

Watch out with your thighs. She's going up by two steps.

- My gosh. - She has an amazing mentality.

That's insane.

(She storms forward even with her thigh pain.)

(She even goes past Seo Yeon.)

Let's do this.

It's already the 36th floor.

It's one-third of the challenge.

(Even the camera can't catch up with her speed.)

(The counterattack of the one in last place)

(She's chasing behind UIe.)

(However, Ace UIe is...)

(Laughing)

(Unlike the members who have trouble keeping their backs straight...)

(and are screaming...)

(She feels relaxed enough to smile while going up.)

I'm not sure about myself now.

I'm not sure what kind of person I am.

(I don't know how far I can go!)

(With amazing speed,)

(she increases the distance between her and In Ah.)

(UIe, 44th floor, In Ah, 42nd floor)

While I'm at it,

I should try to break the record.

(Can UIe arrive in 40 minutes?)

(UIe, 44th floor)

(In Ah, 42nd floor)

(Seo Yeon, 40th floor)

(Where's Ju Hyun?)

My calves feel so tight.

Let's go!

I don't think I can do it.

Don't force yourself. Straighten your legs.

- Let's take it slow. - Take it slow.

I don't think it'll get better now.

Right. Take it slow.

(She endures through her calf pain.)

The 42nd floor.

(She slowly takes each step again.)

After we're done,

- I'm going to have a mango bingsu. - Okay. Great idea.

- A mango bingsu. - A mango bingsu after you're done.

(She's cheering up with the mango bingsu method.)

A mango bingsu after I'm done.

You won't gain weight even after having three of them...

since you've worked out so much.

- Really? - Yes.

Gosh, three?

- I must have it. - You've burned so many calories.

Gosh, that sounds amazing.

Three?

We've already reached halfway. That's amazing.

We've climbed up as much as the 63 Building.

(Ju Hyun, 60, Seo Yeon, 68, In Ah, 69, UIe, 70)

(The members have climbed up the halfway point.)

(They have exactly half of the time left as well!)

(There's a lot of groaning as they go past the halfway point.)

The numbers look blurry.

(Mental Kim's wise sayings have returned again.)

"The ones who are capable will get it done."

(They are passing by in order.)

Those words are for me!

Understood.

(The one with Iron Mentality is the only one that looks calm.)

(Even if their bodies break,)

- Let's go! - Let's go!

(the ones who are capable will get it done!)

(Groaning)

(Groaning)

(The eldest endures through it with a shout.)

My gosh.

(The camera team gets exhausted at this point too.)

(They lose UIe.)

There are still 50 floors left.

(It's currently the 73rd floor.)

- Am I wrong? - Don't say that.

(You're not allowed to say things that make you feel more tired.)

(While going up in silence...)

Sir!

I can't stop even though you look exhausted.

I'm sorry!

I'm sorry!

(The human bulldozer starts storming forward.)

Gosh, this is making me feel competitive.

I don't think I can go up if I take a break.

(UIe goes past the 80th floor without taking a break.)

That is why I'm carrying on.

(UIe goes past the 80th floor without taking a break.)

I don't know myself anymore.

I can't stop my legs.

(UIe goes past the 90th floor.)

(She's strengthening her mentality.)

(I've seen people say that they're about to die,)

(but I haven't seen anyone actually die.)

(From "Kim Dong Hyun's Mental Training")

That's right.

No one has actually died.

This is what my trainer always says to me.

(In Ah also goes past the 90th floor's wise saying zone.)

I won't die.

I won't die!

I won't die from this.

I won't die from this.

Get yourself together. You can do this.

(UIe and In Ah have gone past the 90th floor.)

(Seo Yeon appears at the 83rd floor with heavy breaths.)

They're amazing. Those outrageous ones.

I can't stop.

(The eldest enjoys a scalp shower before heading back up.)

(They are aiming for the 123rd floor,)

(and 30 minutes have passed.)

(The one in the lead is getting closer to the top.)

How can I come back here now?

(Feeling sick of this place)

Gosh, it's the 100th floor.

(UIe reaches the 100th floor!)

(She has gone past the 100th floor, but the stairs have no end.)

(She's drenched in sweat, but she does her best to take each step.)

Gosh, it's making me curse.

(There's another person heading to the top that is a bit tough.)

Gosh, save me.

Save me!

I was about to die earlier.

(She was about to die, but she takes 2 steps again.)

Let's rest at the top.

(She's going up by two steps with true madness.)

Let's rest at the top.

(The 2 of them have only around 10 floors left now.)

If I rest my legs,

(She looks calm in the lead.)

I think my body won't be able to handle it.

(UIe reached the 116th floor without taking a single break.)

It looks different here.

Gosh!

It's impressive!

It looks nice!

It feels like I'm at a lounge bar.

(The way to Jamsil Tower's observatory!)

(If you have entered this area,)

(it means you are close to the top!)

It's giving me more strength here.

Is this the runner's high?

(Chuckling)

I keep laughing.

(She keeps laughing as she gets closer to the top.)

Gosh, you're something, UIe.

(The 120th floor)

(The 121st floor)

Gosh.

(The 122nd floor)

Gosh!

(It's finally the final floor.)

It's the end!

(She climbs up the last set of stairs...)

(and heads to the finish line.)

Gosh.

(UIe completes the vertical marathon in 35 minutes and 23 seconds.)

(She checks her record.)

What? Did I just come in at 35 minutes?

How did she make it in 21 minutes?

How is that possible?

(But UIe's record is really fast too!)

Hold on. Is there five minutes left?

I came up without taking a break.

(If there are 5 minutes left without taking a break...)

Our members are in trouble.

(The happiness doesn't last long. There are only 5 minutes left.)

(Where are the other members?)

Keep going, my thighs.

(Her taping has come off during her run.)

(The 120th floor)

Don't stop.

Keep going even if you want to stop!

You're almost there! Keep going!

I can't move my legs.

(She seems to have reached her limit right before the top.)

Hey!

(UIe came down to look for her members.)

There are five minutes left!

(She hears UIe's voice calling for the members.)

Darn it!

(She does her final sprint.)

There are five minutes left.

(She takes two steps at a time again.)

Let's go!

(She forces out her remaining strength with her support.)

Where is it?

Over here?

That's right. Go inside.

(She has finally made it!)

(The tough fight against herself is finally over!)

(In Ah completes the vertical marathon...)

(in 36 minutes and 24 seconds.)

My gosh.

(In Ah makes a great finish after using all of her strength.)

(She is knocked down.)

What's my record?

(She checks it herself.)

(Screaming)

(Screaming)

(A sense of achievement...)

(that only the ones who have endured through pain can feel)

(She sets a record just a minute apart from UIe.)

But I can't get up. I can't feel my thighs at all.

My thighs hurt so much.

(In Ah's thighs that have gone through so much will take a rest!)

(The top two have reached the top.)

(Retching)

(Retching)

(Retching)

(Seo Yeon goes past the 90th floor while retching.)

(Wise saying time)

(But I haven't seen anyone actually die.)

(Mental Kim appears when you are about to die.)

I get it.

(She's sick of it now.)

(Panting)

(Shouting)

(Iron Mentality's 123-floor method, giving out a shout)

I'm a machine.

I have to set that mindset.

(Brainwashing herself)

(Yoga breathing?)

(She keeps her mentality in various ways.)

It's the 100th floor. Should I take a picture?

(I have reached the 100th floor. I'm quite impressive.)

It's the 100th floor.

(I have reached the 100th floor. I'm quite impressive.)

It was nothing.

It was nothing.

I can do this.

I can do this.

(Seo Yeon has reached the 100th floor.)

I'm sweating so much.

- My calves are killing me. - What do we do with them?

Gosh. I just have to go.

You're right.

My gosh.

(She keeps going with her dogged spirit even though it hurts.)

- Can I move on all fours? - That's fine.

(She starts moving on all fours.)

Gosh, it feels comfortable!

I heard walking on all fours is good for your health.

Right. Let's go like that.

You can go up like that.

I was born in the Year of the Dog.

Right. It's reaching the top that matters.

(The Boktteong method appears here too.)

(Ju Hyun crawls up to the 90th floor.)

(Seo Yeon, 112nd floor, Ju Hyun, 92nd floor)

Members! There are four minutes left!

(There are around 4 minutes left.)

(Seo Yeon finally enters the observatory area...)

(on the 117th floor.)

(She dry heaves every time she walks.)

I'm almost there.

(I'm almost there!)

I'm almost there.

(But she takes each step thinking about completing the race.)

(She arrives at the 120th floor.)

(As soon as she arrives there, she starts taking big strides.)

(The final spurt)

(Seo Yeon climbs up the final set of stairs.)

(Can she arrive within 40 minutes, their target duration?)

(Seo Yeon arrives at the finish line.)

Seo Yeon, it's exactly 40 minutes.

(Jin Seo Yeon completes the vertical marathon...)

(in 40 minutes 19 seconds.)

- Nice. - Gosh.

(Still, Seo Yeon made it in 40 minutes.)

This...

A triathlon competition.

We can go the distance.

(She shoots randomly to celebrate completing the race.)

We can go the distance.

That was very hip-hop-like.

(She's filled with hip-hop spirits from completing the race.)

(She walks toward the windows to catch her breath.)

Gosh, I...

I just saw that.

(What unfolds in front of their eyes...)

Where is this?

- It's that area. - I see.

This is...

(is the view from the observatory where you can see Seoul)

Gangbuk.

(When you make it until the end, you can finally see these things.)

(Seo Yeon, well done.)

- How long did you guys take? - I took 35 minutes. She took 36.

(She acknowledges their strengths.)

We just need to wait for Ju Hyun, right?

- Really. - Gosh. What am I going to do?

(Ju Hyun's location: 106th floor)

- Gosh, this... - What should we do?

(She fails to make it in 40 minutes.)

- This is... - You can take a break or give up.

You made it this far.

I can't accept giving up here.

Okay.

(Limping)

Good job.

- Let's go. - You're doing great.

(Struggling to complete the race no matter what)

Gosh, this...

(But...)

You can do it.

Let's take a break. Sit down.

(her legs stop moving.)

I think it's better for you to rest.

My calves became bigger.

Yes, your muscles...

What to do? Relax your legs.

(In the end, Ju Hyun flops down.)

- Gosh, here. - Okay. Relax.

Here.

You need to relax your muscles.

(Her body won't cooperate with her.)

It's so annoying.

What should I do?

This might happen during the competition.

You're hanging in there well.

You should've given up way earlier.

(Actually, you should've given up way earlier in this condition.)

(Can Ju Hyun continue the challenge?)

This is driving me mad.

(Can Ju Hyun continue the challenge?)

(47 minutes have passed.)

(They are starting to get worried about Ju Hyun who isn't coming.)

(At that moment, UIe goes back to the stairwell.)

(She looks down to check if Ju Hyun is coming.)

Gosh, Park Ju Hyun.

(Concerned)

(Meanwhile, on the 109th floor)

It's the 109th floor.

We're on the 109th floor. You did make it far.

- Let's go. - Can you do it?

What else can I do?

If I give up now, I won't be able to complete the race...

on top of injuring my calf.

I can't let that happen.

The 110th floor. You can do it.

The 110th floor.

- The 110th floor. - She's coming.

(Concerned about Ju Hyun who is not coming,)

(UIe runs back down.)

(Out of her concern for Ju Hyun,)

(she runs down more than 10 floors at once.)

- The 110th floor. - Ju Hyun.

- UIe. - Wear this.

- But if I wear that... - It's better without it.

Is it better without it?

It hinders blood circulation.

Here... Don't cry.

The 17th, 107th... No, the 117th floor is dark.

Okay.

- I got cramps... - Did you get cramps?

on my calf, yes.

(They hold hands and walk up.)

Looking at you makes me tear up.

- Seriously. - I'm going to take the elevator up.

- Go take it now. - Okay.

(She makes a joke in case Ju Hyun feels sorry.)

Ju Hyun. When you reach the 117th floor,

it is a lounge bar.

It suddenly becomes dark, and you'll see a galaxy.

- Really? - Yes. Just a bit more.

(UIe gives Ju Hyun strength so she doesn't give up.)

You made it so far.

- Yes. - Less than 10 floors left.

- Last one. Nine left. - Yes.

(With their support, Ju Hyun walks up without stopping.)

- Gosh. - Gosh.

Oh, no.

Goodness.

It's very short. Right here.

(Ju Hyun finally enters the observatory section too.)

What is this?

- Isn't it cool? - Yes.

(Only 5 floors left to the top)

You're almost there, I swear.

The final five floors.

(Her injured leg weighs her down more and more,)

My leg feels so heavy.

(Her injured leg weighs her down more and more,)

It's no joke. The view...

(but Ju Hyun gives it her all until the end.)

You're here.

- You only have one floor left. - Just a bit more to go.

- Just a bit more. - Take it easy.

(She clenches her teeth and take each step with a struggle.)

You're here.

Keep it up. You're here.

- You're here. - I'm here.

You're here.

(The final steps to the 123rd floor)

- I'm here. - You're here.

(The finishing line is right in front of her.)

- You did it. - You're here.

Here?

- Okay. - Let's go.

You made it.

- Park Ju Hyun. - Park Ju Hyun.

- Park Ju Hyun. - Park Ju Hyun.

(With the sound of people supporting her from afar,)

- Park Ju Hyun. - Park Ju Hyun.

Gosh.

- Park Ju Hyun. - Park Ju Hyun.

(Park Ju Hyun completes the vertical marathon in 54 minutes 32 seconds.)

Goodness.

- Gosh. - It's so nice.

The view is amazing here.

- My calf. - Okay, you did great.

Did you go to fetch her?

- Sorry? - Did you go to fetch her?

(Good job)

Her calf started acting up from the 30th floor.

She limped all the way up.

About 100 floors.

It was so painful.

- She did great. - Ju Hyun.

You did it.

You did it.

- You succeeded. - Good job.

Good job.

You completed it.

- That's what matters. - That's what matters.

Goodness.

(They experienced completing the race,)

(which is more valuable than the record.)

(After the vertical marathon training ends...)

(Spraying)

She's still an actress,

but she's being too comfortable like she's at her home.

I'm having trouble with blood circulation.

- She looks very comfortable. - When you sit there,

it makes you feel comfortable.

It looks like she completed a triathlon.

(From the looks of it, she completed a triathlon.)

When you run a triathlon,

you might have an upset stomach because of the food...

or you might have thigh cramps.

You faced those situations today.

Nonetheless, you overcame it.

That mentality will help you in the competition.

You didn't give up,

- which is amazing. - We never give up.

One, two, three.

- Gosh. - I don't have any muscle.

Three.

- Thank you. - You worked hard.

You worked hard.

It was really meaningful.

It was really meaningful today.

(Iron Girls have visitors.)

(Iron girls from all around the nation)

(The best cardiac endurance sport, track and field)

(The strongest women, Health Grandma)

(The strongest mentality, soldiers, cops, firefighters)

(The best stamina, national athletes)

(Iron-like women's...)

Things are getting heated up here.

(I'll tear them apart.)

(Introverted In Ah fires up.)

(Even if she feels like dying,)

(she pulls through in the end.)

(Iron DNA)

Step aside.

(Who will win this competition?)

(And...)

(A cheerful shout)

(The iron-like training ends, and a happy training starts.)

(The first cycling training)

(It's fun.)

(An unexpected healing time)

(It's cool.)

(Shouting)

(UIe cannot ride a bicycle.)

(She seems to be doing well.)

(Are you scared?)

(I can't do it.)

(The side of Ace UIe we've never seen before)

(She has a bicycle trauma.)

(Can she overcome it?)
