Cannonball is a great warm up, overhand throwing aid, and pitching aid. Originally designed for rehabilitation, it is an excellent trainer for building strength in the throwing arm and shoulders. The ball is available in red, yellow, orange or blue and weighs one pound. It is made of hard rubber which guarantees it for life. Professional pitching coaches use it for strength and wrist spins. The player interested in improving the overhand throwing motion with the ultimate wrist snap and range of movement needs to include the Cannonball in their routines.
