I don't play myself, but am seriously considering it, as with each passing year it gets harder to gather 10+ people to play a decent soccer-game. People are gettin older I guess.
My only concern is that Tennis isn't to easy on my knees either, as I already feel them aching a bit.
iJohnHenry, thanks for that!
I play a few times a month with friends. It's a lot of fun not only playing the actual game but working on your techniques and trying new swings. I'd definitely recommend getting into it.
trying to master serving!
This is a life long pursuit for a tennis player. A good consistent service game is a difficult skill to perfect.
For now, I'll settle for getting a good number in the service box!
