your right freemen mabey some aspecs do invole Muscle strength. So i will put my point a nother way, when doing certain techniques like irimi nage there is no use for strength. Now i am 6 foot and 245 pounds, now obiviouly if i wanted to i could put most people down with irim nage using the physical strength i have. But doint this shows nothing, but doing technique makes it "a technique worthy of a poem" Kissumara Ueshiba. you see what i am getting at. Take a nother example, there is a guy in my class, he is only 5"10 175pounds, now if he was to irimnage just using his muscles, it wouldnt happen, but if he throws tehcnique in there he will drop me.
