your oach is like most coaches, an ex-fighter that never made it to the real big time as a coach. he don't know jack about what he is saying. power comes from correct body alignment and making sure each move doesn't bleed energy away from the desired task. simple to say hard to self -analyze. find a better coach. on a side note great thing to tell someone that is going to get into a ring where homicide is legal and mess with his head...good job. drop him like a toilet seat
