I'm sorry, its difficult to understand what you are saying with the way you use your words. If your profile is up to date, then I take it you're not a WC practitioner? If so, I can understand why you aren't grasping the concept. WC movements are different then most martial arts. I laugh at the thought of calling a practitioner an athlete though. Well, there may be athletes...that happen to know WC, but becoming an athlete from WC is nearly impossible unless you're doing things wrong.
From practicing WC my arms and chest have lost muscle. 6 pack? yeah right. I use that mini buddah down there to generate power.
There is one guy in our class that is somewhat muscular. He has the most difficult time, compaired to the rest of the class, doing the motions properly.
