Nishiyama - We've (our club) been studying the subtleties of movement. The term I've coined is" Karate Movement Physics". We've made some incredible discoveries. Nishiyama sensei worked so hard especially the last 8 years cramming the purest, most refined principles of this beautiful art to those that were there to listen. The past almost 5 years (since his passing) now have been of incredible discoveries. A time of sifting through all this information, expanding and continuing the study, moving forward. I'm not saying my kicks are good here but they are the best they have ever been, no warm up and the movement feels free. Just saying one must practice everyday.
