I think we all have played against those players that have to much "weight" behind their groundstrokes. I don't really know how to describe it other than that; the ball feels "heavy" and it's coming at you hard. Not necessarily fast, (though sometimes fast..) as much as just always "heavy." I hope that makes sense. I hit with a D1 college player that fits this perfectly. My question is how. Is it purely technique? Is it finely tuned racket/strings to the players desire? Is it hitting the weights in the gym? Is it all three? (I bet it is...) Anybody have any personal advice on how I can achieve this heavy ball? I took a month off during winter break, but now I'm back at school with the gym and pool. I've started (for the first time ever) consistent conditioning in the pool, 3 days a week. Before the break I was working out 4 days a week, and I'm going to start that up again but I think only two days a week now. Is that a good balance between conditioning and weights? TL;DR ... What can I do to get some umph or weight behind my groundstrokes?
