technique on baseball throwing?

I saw your age on your profile and you're past the point where you have to worry about damage to your arm. I'm not sure whether you mean pitching or throwing. I was a second baseman and had to learn to throw over the top, 3/4 and across my body. I found that weight training was helpful...I used the same method as I did when I boxed...lighter weights and more reps. I used a pitchback set-up to get my accuracy. There are books and videos on every aspect of the game...maybe you want to check out a couple. "Baseball...hell, it's the ONLY game!" Babe Ruth
