I believe kim Jong kooks friend still has that old tradition mentality when the people in Korea didn't really care much about gym fitness which is understandable, but look how huge of an impact it has become. Now u see all the huge kpop stars want to have that ripped body and Korean's finally understanding why gym fitness is so big and popular. There is a reason why Kim Jong kook has 1million subscribers because alot of fitness trainers follow him too because they are also gym fanatics aswell and respect Kim Jong kook for keeping such an amazing body even for his age. U dont rarely see people look that good at his age. I'm happy my dude is getting his recognition. He worked hard for it. Sparta fighting. 💯💪👍🤙
