A question for anyone who can answer it: With regard to a simple reverse punch, has the technique been improved upon bio-mechanically recently or are we talking about building faster, stronger, bigger athletes through 'modern training methods'?
I figure I would start a new thread. Personally, I think that the reverse punch, as trained on a makiwara, cannot be improved upon biomechanically. I think that the makiwara trains you to be biomechanically correct. Where the modern training methods would come in is as archtkd said, in the footwork, distancing, timing and set up immediately prior to launching that punch.
