Yeah, the sprints I think I'm trying to design them as a more organized version of the workouts I've been getting from basketball. I've been doing plenty of sprinting and certainly lots of running up and down the court. I now want to do it in such a way that maximizes the efficiency of the workout.
As more and more folks have shown up to play basketball, and as court time has then become more scarce, the more aggressive the kids have gotten trying to win and stay on the court. So in my opinion there's starting to become WAY too much contact for what's supposed to be an informal pick up game. Naturally tempers are also starting to flare up, though fortunately I'm never a part of that. All and all, playing in these games are becoming less of a good idea for workout purposes. I've gotten banged up a bit (hyper-extended my arm a bit last week), but never anything serious. But I'd also like to keep it that way. Have had no luck trying to find an over-40 league thus far.
Seemed to handle the sprints fine yesterday and I'm going to monitor how I feel when I do them. I want to target body fat specifically at this point, and all of the most recent research suggests sprints are a great way to that. Thanks for the book suggestion, Q, I'll have a look.
