Basketball has allways been my idea of the best workout.
I actually like 3 on 3 halfcourt, because it's all acceleration and quickness, without that long up and down the court run.
Alas, physical prowess to improve my game has left me a while ago, what with sprained ankle, pinging knee, sore hips, so maybe bigger hitting is my next goal.
But YEA, great you are still improving, and you can now start to hit bigger with your new stamina and footwork!!!
