How can you improve the service return when the ball comes into your body. Most of the time I am a bit "lazy" and do not move out of the way and try to compensate with the racquet. It's not a matter of being late, since I am normally more early than late on the return. Any tips? maybe some drills? How important is the initial position, when you look at the pro's they are relatively 'low' on their feet (e.g. Hewitt). Do you have to jump up when the opponent hits the ball? Any help is appreciated!!
