dude, Ive trained with some of the best fighters in the world in kickboxing, dail frye former world lightweight champion, dennis weaver former us middleweight champion, rick rufus former world champion, and probably the most unrecognized fighter in the world, joe lewis former middleweight and 5 time heavyweight champion, and all of those guys have deep tkd backgrounds. the smallest of all, dale frye broke three of my ribs sparring with a jump spinning back kick. power is defined by technique, and I'm just saying that tkd has some of the best kicking techniques in the martial arts world
