On June 1, SBS’s My Ugly Duckling aired an episode featuring actor Yoon Si Yoon, who gave fans a rare look at his daily life and impressive physique.

Yoon Si Yoon showed his very tidy home and explained why there’s no place to lie down except his bed.

He said he keeps his house clean because he doesn’t want to get lazy. To stay on track, he even sets alarms to remind himself of his schedule.

Every day, Yoon Si Yoon starts with exercise. He said he’s working hard to look tired for his role in the drama Taxi Driver 3.

So far, he has lost about 10 kg and now has only 6.5% body fat. His goal is to get even leaner at 5% body fat.

On the show, Seo Jang Hoon shared, “Kim Jong Kook has 9%. For a normal person, that’s almost no fat at all.” When Shin Dong Yeop asked about Kim Joon Ho, Seo Jang Hoon joked, “About 40%.”

Yoon Si Yoon worked out with many different exercises to get closer to his goal. After his workout, he checked himself in the mirror and proudly showed his defined abs. Shin Dong Yeop couldn’t help but say, “I want to live one day with that body.”

Yoon Si Yoon’s dedication is clearly paying off, and fans can’t wait to see his new look in Taxi Driver 3!
