medicine ball rotations, wood chops, diagonal wood chops, rotational throws, squat & throws, granny throws... Medicine balls are great for developing explosive power! The key is to keep the ball light enough that you can explode with it. I keep all of my ball players under 10 pounds and most of them under 8 pounds for all of our drills.
The following link (scroll down toward the bottom) shows one of our Minor Leaguers performing our favorite drill for pitchers, the Med. Ball Pitchers Throw!
