The secret behind Kim Hye-soo's extraordinary physique

Fellow actors have expressed their amazement at actress Kim Hye-soo's flawless physique. However, behind the admiration for her "natural body" lies rigorous dietary control and consistent exercise.

A video was recently released on the YouTube channel 'PDC by PDC,' featuring the lead actors of the Coupang Play series 'It's Not an Affair Right Now'—Kim Hye-soo, Cho Yeo-jeong, Kim Ji-hun, and Kim Jae-cheol.

While enjoying a meal together and sharing behind-the-scenes stories from the production, Kim Ji-hun drew attention by mentioning Kim Hye-soo's surprising eating habits.

"What surprised me most during filming was that senior Kim Hye-soo eats a lot," Kim Ji-hun said. Recalling scenes where she wore lingerie in the production, he added in admiration, "You can see her silhouette, and there is absolutely no belly at all."

Kim Jae-cheol also expressed agreement, mentioning Madam Jeong from the movie 'Tazza: The High Rollers.' Kim Ji-hun offered high praise, saying, "She is so slender and long. Looking at senior Kim Hye-soo, I felt like I still don't fully understand human anatomy. She is a person with a physique that is beyond my common sense."

In response, Kim Hye-soo laughed bashfully, quipping, "My acting should be the impressive part," which turned the scene into a sea of laughter.

However, such a physique was not the result of just a natural constitution.

In 2023, Kim Hye-soo personally revealed the rigorous management methods she used on the same channel to fit into her dress for the Blue Dragon Film Awards.

At the time, she confessed, "I have even tried starving myself." She explained that while her weight increased due to traveling during the filming of 'Tazza: The High Rollers,' she chose short-term fasting because she lacked time to exercise.

She recalled, "Someone told me to try starving, so I actually did, and I lost 1kg per day."

She also revealed her diet from the day before the 44th Blue Dragon Film Awards. Smiling, she said, "I ate a little yesterday too. Two apples?" implying she survived on just two apples a day to fit into her dress.

Of course, she now manages her body through consistent exercise instead of unconditional starvation.

After experiencing burnout following the filming of the drama 'Under the Queen's Umbrella,' she took about a year of rest, using that time as an opportunity to focus on exercise. Since then, she has continued consistent self-management to recover a healthy physical state.

Recently, she shared footage of herself exercising on an aqua bike underwater via her personal SNS. Underwater exercises such as the aqua bike, aqua walking, and aqua dumbbells are known to be her representative management methods, which she has maintained for about five years.

While she eats more deliciously than anyone else at the dining table, Kim Hye-soo completes a flawless silhouette in front of the camera.

The reason her fellow actors marveled at her "extraordinary physique" lies in her thorough self-discipline and steady effort rather than just her natural constitution.
