Hi I'm looking for a manga I read a long time ago so I don't really have alot information about it. I think the martial arts is kickboxing or muay thai. It is a guy who is sent to a camp where they train the martial arts and I remember that he breaks a sandbag. ( Think it was with his kicks?) There is also a guy at the camp who trains to lose weight. That is all I can remember about it I'm really thankful if anyone could tell me which manga it is! I stopped reading it because it wasn't completed so I want to re-read now xDD
