Actress Yujin reveals her diet secret.

In the upcoming episode of KBS2's 'Problematic Men in the Rooftop Room' airing on the 25th, Yujin, a member of the first-generation girl group S.E.S. and the lead actress in the drama 'First Lady', will appear.

With her timeless beauty, Yujin shares her body management tips with the rooftop MCs. Yujin revealed that she lost weight while preparing for the drama, impressing the MCs with her appearance.

The diet secret Yujin shared is stair climbing. Yujin, who climbs 32 floors for 10 minutes every day, said, "By engaging my thighs and glutes while climbing, it has a hip-up effect," and actively recommended the 10-minute stair workout.

Yujin, who consistently does stair exercises like a female Kim Jong-kook, received support from Kim Jong-kook, who reportedly said, "Stair exercises are recommended by world-class models; I do it five times as well."

Yujin's hidden arm wrestling skills will also be revealed. In fact, Yujin won an arm wrestling championship in a past variety show, even managing to K.O. Lee Seung-gi, which surprised the rooftop MCs.

Yujin showcases her down-to-earth charm as she competes in arm wrestling with Joo Woo-jae in the rooftop room. The arm wrestling match between 'female Kim Jong-kook' Yujin and 'the skinny guy from the rooftop room' Joo Woo-jae was reportedly so intense that Joo Woo-jae was left in despair.

'Problematic Men in the Rooftop Room' will air on the 25th at 8:30 PM.
