I recently decided to start warming up my arm for the baseball season. I set up my net at the top of the my driveway (about 50 -60 feet long) and I get a small hockey net and throw into it, the driveway is on somewhat of an incline, but not to the point where I am throwing way to high. Basically, every time that I throw a pitch that enters the net, whether it being a fastball or breaking ball or changeup or whatever, if it is a hard thrown/good pitch, it counts as a pitch, and I count up to 100 good pitches. Is this worth it/dangerous/useful etc.
(btw I am sixteen and have been throwing for a long time, and I wasnt really sore the day after throwing the ball)
