Champro Training Softballs, Set of 4 (Green/Yellow/Black/Blue, 12-Inch)

OVERLOAD TRAINING SET: The CHAMPRO Weighted Softball Training Set provides a way for players to improve their in-game performance. Many players agree that training with weighted balls can increase their velocity when playing with a regulation game ball. STRENGTH BUILDER: Train with the progressively heavier balls in this set to work on building arm strength and throwing velocity. PITCHER TRAINING: CHAMPRO’s weighted training softballs have stripe patterns that allow pitchers to monitor the pitch rotation, helping them develop their skill set. DURABLE CONSTRUCTION: These 12" balls have raised seams and full grain leather covers that are made to last. INCLUDES: The set comes with 4 progressively heavier balls--one 9, 10, 11, and 12-ounce ball--and a training program to help athletes get started right away.
