This is a very strange thread. So for example, when I go back to Wing Chun and probably in six months or so, if I added a knee practising Chi Sau, would that be in affect be making things up. Sorry I just fail to see that, surely the knee is a add on and has no tangible affect on Wing Chun? Surely if MMA was making things up as it goes along, where is the coherence in that. Someone tries a new move been made up, a kick to the neck for example would likely paralyse. Sorry, I just don't get it.
A Martial Art is based on coherence honed by generations, making something up on the fly is all well and good, but has to based on coherence of whatever art you do. The sandbox is simply not that vast. Is MMA not made up of Boxers, Wrestlers and Grappler's, what new move made up could possibly be safe on the fly. Rambling over, going to go and be confused.com elsewhere.
