Kim Jong-kook's YouTube Channel Features 'ONE High School Heroes' Cast in Leg Day Workout

Kim Jong-kook's YouTube channel, 'Kim Jong Kook GYM JONG KOOK,' recently uploaded a video titled 'Leg Day You Don't Want...(Feat. Lee Jung-ha, Kim Do-wan, Yuk Jun-seo, Choi Han-jin).'

In the video, Lee Jung-ha, Kim Do-wan, and Yuk Jun-seo announced their return in 'ONE High School Heroes.' Lee Jung-ha shared insights about the project, stating, "You can see and use the opponent's martial arts techniques," and added, "I practiced Taekwondo at an action school as if it were my home to prepare for various martial arts."

Yuk Jun-seo revealed that he practiced boxing. Kim Jong-kook, curious about Yuk Jun-seo's career shift, asked, "How did you suddenly dream of becoming an actor?" Yuk Jun-seo was momentarily speechless, prompting laughter when Kim Jong-kook remarked, "It seems like you don't know your future direction."

Kim Jong-kook then suggested, "Since there are three of you, it's a perfect time for leg exercises," and instructed them to start with simple stretching. He emphasized the importance of flexibility, saying, "You must develop flexibility."

He explained, "If you're not flexible during any exercise or movement, your lower back can curve, which can lead to issues like a herniated disc." Kim Jong-kook demonstrated proper techniques, stating, "I think leg exercises are urgent for you three. We'll focus on loosening the back part perfectly before moving on to exercises."

After the challenging workout, Yuk Jun-seo humorously remarked, "I think I'll just sleep tomorrow," while Lee Jung-ha added, "I don't think I'd do it without compulsion," eliciting laughter. Kim Jong-kook, smiling, said, "On leg day, eat well and dedicate one day a week to it." Yuk Jun-seo concluded, "Even though my eyes can barely open, it was an honor to learn such leg exercises."
