I have always been a believer in pre emptive striking. I have been pre emptive striking since first grade.
I prefer covering over blocking. And blocking combinations is a problematic to near impossible. Is one of the problems of blocking and trapping. I have never had anyone block me and I have never hand a problem getting around someone cowering and covering. So Im pretty convinced trapping is theoretical non sense but I have never trained it but I have never trained the Dim Mak either..lol
I still would love to see someone doing trap against a fully resisting oppenent attempting to knock them out. The footage doesnt exist because trapping is BS.
