I have found in reading the tao of jeet kun do that bruce lee was some form of higher self bring truth in its purist form of simplicity.There is another book out there with even more material, it is at barnes and nobles. One day i will find it on the web until then have a whole good time. Oh, super joints is a Russian stretching book,not in Russian though.I feel really good and I believe these exercises have helped me along with full body breathing or as in the matrix 4 powerbreath or chargerbreath.
