Kim Jong Kook has opened up a personal YouTube channel 'Gym Jong Kook'!

On June 17, the 'Running Man' cast member posted his first video on his channel, and fans weren't surprised to see it was about exercise and fitness. Kim Jong Kook wrote the message, "I dare say I opened up a YouTube. The only license I have for this channel, Gym Jong Kook, is my body."

He continued, "I'll sympathize you with various content in the future. We'll try our best to be a channel that can share! I hope you evaluate your exercise with sincerity and consistency rather than with your visible body! Until the day you contribute a little bit to making a healthy Korea! Let's go together!"
