I've been taught the same so I agree. In terms of the hand technique it's pretty interesting. It reminds of of the whipping like power I've read about. Yeah I can't say exactly for him I mean he seems legit but obviously I can't vouch but I do agree with having a strong foundation. I could say atleast in today's society it's lacking due to people not wanting to put in the effort. I've noticed with new students when I teach they really can't handle it, aren't interested, or some other silly reason and really just want those Flowery techniques but that obviously like you said can cause issues.Ok but he is not on his legs. No foot no punch. That type of patty cake strike won’t get very far outside of a forms competition. This is my biggest issue with CMA videos, it’s usually just flowery hands and no basics foundations. Yes it’s a leopard fist, but used like that, it’s just as useful to cut the hand off and throw it at the opponent. He talks about the circling motion, but the circle is from the humerus bone not the wrist. No shade on you, just saying that the bulk of YouTube videos on CMA are crap.
