Punching through a piece of wood and wiping (or scraping) marks off of stone on the ground are 2 different things completely. I seriously doubt XF's training in punching, jumping, running, and other fighting techniques really helped him in an act like swiping his feet and clearing marks off of the ground. That's like assuming just because one guy has been training to play basketball all his life he would automatically turn out to be a great golfer as well. (Ask Michael Jordan or Charles Barkley how good their golf games are). <IMG SRC="smilies/smile.gif" border="0">
If anything, JY, being the monk that he is, would have had more practice sweeping and cleaning the ground than XF. <IMG SRC="smilies/tongue.gif" border="0">
