5 Korean Actresses With The So-Called Teeny-Tiny "Ant Waist"
Find out what they do to maintain their figure!
In It's Okay to Not Be Okay's Episode 6, Korean actress Seo Ye-ji (as Ko Moon-young) visited the OK Psychiatric Hospital wearing pastel pink separates—a long-sleeved cropped top and an ankle-length skirt. The feminine and fresh color looked fabulous on the ever-stylish character, but it was not the first thing we noticed the moment Ko Moon-young emerged from her car in this outfit. It was her teeny-tiny waist, emphasized by her ensemble's silhouette!
A millennial slang, "shookt" is perhaps the best adjective to describe how netizens reacted to this viral look! Some said she looked like a real-life Barbie; well, we all know how exaggerratedly small this iconic doll's waist is! Some mentioned that Seo Ye-ji now joins the list of Hallyu stars with the so-called "ant waist," a term used to refer to a shockingly tiny waist.
The term "ant waist" has been associated with a number of K-Pop idols, such as BLACKPINK's Jennie and Lisa. Their work entails a lot of dancing, so that's one form of exercise for them. Jennie was said to be a fan of Flying Yoga (or aerial yoga), an anti-gravity fitness that combines traditional yoga poses, Pilates, and dance which utilizes a hammock; it's believed to improve strength and increase flexibility. For Lisa, her go-to workout is Pilates which helps improve her flexibility and strengthen her core. Their group reportedly also has a diet plan that's all about controlling portions and monitoring the calories.
Scroll through the gallery below to see our list of Korean actresses who are now part of our growing list of fitspirations:

Seo Ye-Ji
First on the list is, of course, the 30-year-old Seo Ye-ji. The "It's Okay to Not be Okay" actress is petite. Her height is 169 cm and she's only about 43 kg. This is why she can pull off any outfit in the show, whether it's form-fitting or billowy.

Seo Ye Ji
Her waist is so unbelievably small some viewers thought it was CG, like some elements in the show. But no, it's not. Seo Ye-ji actually has her genetics to thank, because her mom and her sister are said to be tall and slim as well. In a press conference, she was quoted, saying, "I don't go on diets. Being thin is just in my genes... Everyone on my mom’s side of the family are tall and thin. It just runs in the family."

Seo Ye-ji is said to be a fan of yoga. As seen in "It's Okay to Not be Okay," wherein her character is a fashionista, this posture-enhancing activity clearly has a great effect on her stance. If we can't be as thin as her, well, at least we can exude confidence with good posture.

Son Na-Eun
Son Na-eun is a K-Pop star from all-girl group Apink, who has also ventured into acting. She had supporting roles in several dramas like "Childless Comfort" and "Cinderella with Four Knights." But just recently, she was cast as one of the lead stars in the series "Dinner Mate," wherein she played the role of a fitness instructor; you have to see her workout outfits in the show!

Son Na-Eun
She's one of the K-Pop idols who are famous for their "ant waist." Son Na-eun is 167 cm tall and she weighs 45 kg. Back in 2015, she made headlines for having a 19-inch waistline, but she worked out and exercised to get more toned muscles, and put on a bit of weight. Her choice of exercise is doing squats. In an interview, she mentioned, "When overseas activities prevents me from regularly visiting the gym, I still do squats at home. I do five sets of twenty daily, which works out not only my legs but also my entire body. I even rid of the cellulite on my buttocks which I thought would never go away." Now her waistline is said to be at 22 inches.

Son Na-Eun
When their group Apink just debuted, 26-year-old Son Na-eun limited her diet to merely salads. She also pointed out the benefits of sodium-free food in a 2015 interview with "Sure" magazine: “You don’t gain much weight when you eat sodium-free foods. The results are good. When I get hunger pains, I drink tomato juice which keeps my appetite. I replace my breakfast and dinner meals with detoxing juices when the comeback is near."

Han Ye-Seul
Han Ye-seul is popular for her K-Drama "The Birth of a Beauty," wherein she played the role of a woman who went under the knife to get back at her cheating husband. In real life, though, Han Ye-seul is known for being hardworking when it comes to maintaining her physique. In a YouTube video, she shared some tips when working out: "I take a lot of breaks. If you go too hardcore right from the start, you’ll end up hating working out... You have to eat in between workouts. You’ll run out of energy otherwise.”

Han Ye-Seul
However, she may have been too obsessed about staying fit that she was once criticized for a photo of a weighing scale she uploaded on social media. It showed that she weighed 49.1 kg, but her caption was "I need to start exercising again." Netizens felt that it was not good for her to give her followers unrealistic and unhealthy weight goals.

Han Ye-Seul
The 38-year-old actress also revealed a secret trick to curb hunger. In an interview on MBC's "Sister's Salon" show, she said, "This is a secret that I only use. It’s really hard to stop yourself from eating when you’re so hungry. So you need to work consistently at something that you enjoy doing. For instance, I like to just take stuff out and clean everything once in a while. While you’re immersed into your work, you don’t become hungry after a while."
Kwon Mina
A former K-Pop idol from all-girl group Aoa, the 26-year-old Kwon Mina has successfully crossed over to the world of acting. When she was still an active member of Aoa, the measurement of her waistline always made headlines, because it was so shocking at only 17.9 inches. No photo editing skills could have ever altered how tiny her waist was, especially when she was dressed up in cropped tops during concerts.

And because Mina's waistline became (in)famous, it even gave birth to a so-called "MINA-mize" waist workout, a waist toning workout that can help one achieve a slim and defined waist, on the Kpop Fitness YouTube channel. It involves the repetition of the following techniques: candlestick dipper, hip dip, and hip twist.

The petite idol-turned-actress weighs 46 kg and is 158.5 cm tall. In an interview, she revealed that she tends to gain and lose weight easily, so she pays extra attention to her diet. She said, "I’m the type that swells (or bloats) easily... No salty [food]. No spicy [food]. Instead I eat a lot of sweet pumpkin and other types of squash.” Kwon Mina also said that she tries to not eat anything more beyond 6PM. She starred in K-Dramas like "Click Your Heart," "Wind-Bell," and "Loss Time Life."

Lee Da-Hee
"The Beauty Inside" and "Search: WWW" actress has a model-like figure, standing at 176 cm and weighing 54 kg. While being tall looks nice, for Lee Da-hee, her height is what constantly pushes her to be on a diet. She said in an interview, "Since I’m so tall and have wide shoulders, I start looking really big if I gain weight. There’s a pretty clear difference [in my body image] when I gain or lose weight. I’m always on a diet so I can lose weight and appear smaller."

Lee Da-Hee
During a press conference for the KBS2 drama "Secret Love" back in 2013, Lee Da-hee said that she always tried to keep her weight at 49 kg. "If I go over 50 kg, I don't eat," she admitted. "When I gain weight, it all goes to my face first... So I don't eat anything."

Lee Da-Hee
In that same interview, Lee Da-hee also revealed that she doesn't like exercising. "The only workout I do is breathing exercise." Not eating anything and not exercising are not the ideal pieces of fitness advice. These were her statements years ago, but it seems Lee Da-hee is getting into the active lifestyle now, as it appears she's been addicted to flying yoga.
