I'm 44 and started playing again about six months ago after decades of not playing. Was really getting into it - bought a new raquet, a ball machine, joined a club, was really getting my game back. I was hoping to join a 3.5 singles league this month to start playing competitively again. And then.... Two weeks ago I fell hard on some ice and broke my left arm - I am right handed (thank god) and it was not a bad break. Still, I haven't hit a ball since and will be out at least another 3-5 weeks. I am planning on doing some running starting next week and maybe take practice swings in my basement daily to maintain the feel for the raquet and my strokes. I hoping to lose as little ground as possible - any other thoughts on what I can do while my arm heals?
