Do most of the people in your gym play tennis? play tennis well? at the world class levels?
Compared to me, rafa is a toothpick (I played offensive line in college football).
The point is that compared to other top tennis players he is more muscular. as is Serena. Why does it work for him, when Roddick, Fisch etc. were thought to be heavy and needed to loose weight to be better players.
I thought the points on Serena were interesting (not the attacks), but that she is significantly more powerful than most of the WTA.
