Why does Nadia Petrova make a muscle with her right arm and point to it after she wins a match at Roland Garros? I've noticed her do that a couple times this tournament. But the funny thing is Petrova doesn't have any muscle definition in her arms! LOL! Nadia has just about the least developed arms I've ever seen! And she has skinny legs, too. She really needs to hit the weightroom! But Nadia sure has alot of natural power in her strokes. Just think of how much more potent her shots would be if she actually developed some muscle.
