This is a little thread for the tennis players who work out to play tennis at high levels. Those who don't work out could also recommend some workout programs. So...What do you do to keep in shape for, during, and after tournaments? I do sit ups everday. And do some weird machine that works out the entire arm, shoulder, and back. All at once Wall sits, leg extensions, and squats The machine's called toe pushers, works out calves like crazy And ladders to work footwork.
