While they can be found in TCMA they've been perfected in application by boxers and the folks who use them in the UFC and other professional full contact fight organizations will train hands from boxing and muay thai. Roundhouse kicks have been perfected by Thai Boxers and the folks who fight in those orgs train Muay Thai for their kicks. It doesn't mean you can't find them in other styles but looking at someone in a professional full contact fight throwing those and going, "wow those are in TCMA too," is a joke. They may exist in TCMA but that's not what e person is training to make them so effective with those moves.Originally Posted by Kellen Bassette
