"RM" Kim Jong Kook surprisingly loses strength competition to a guest! Naughty Ji Suk Jin returns, HaHa exclaims: "Are you a thug?"

The "Become Young" special of the SBS variety show "Running Man" which aired on the 2nd, invited Zhou Xian and Yin Chengbin as guests.

As soon as Jeon Jungkook saw Yun Seong-bin, he said, "I thought Kim Seok-jin was here." Yun Seong-bin also laughed and replied, "I often hear people saying that." Although Yun Seong-bin has retired as a skeleton athlete this year, he still maintains his muscle mass. Kim Jong-kook immediately began praising, "Although you have retired, it feels like you could win medals again if you participate in other events."

Korea implemented the actual age system starting from June 28th, allowing almost all young people to "get younger" by 1~2 years. Thus, the production team stated that this episode was created to commemorate becoming younger. During the warm-up segment, Jungkook was pitted against Song Ji-hyo. Jungkook, who was previously always single-sidedly suppressed, was very nervous. After Jungkook initiated the attack, Song Ji-hyo, who was initially motionless, directly pushed back, intending to only push him away, but ended up forcefully suppressing him. The crowd erupted in laughter when he couldn't help but shout, "Are you a bully?"

In addition, Kim Jong-Kook was pitted against Yoon Seong-Bin. Kim Jong-Kook took the initiative and said, "I can do lower limb exercises until midnight." However, after being attacked by Yoon Seong-Bin, Kim Jong-Kook was startled by Yoon Seong-Bin's strength: "He's very strong, I almost got pushed down!" He even said that Yoon Seong-Bin resembles his younger self, "I used to be like that, you'll get old and see." He struggled to maintain a calm demeanor. Kim Jong-Kook, shocked by the reality, added with a laugh, "I have never been like this when I competed with Ko Dong-Brother before." Yoon Seong-Bin also said, "I feel like I'm really looking at my future self."
