The Champion Sports weighted training softball set allows you to gradually increase the weight of the ball as your arm strengthens. This set of 9 includes balls weighted from 4 to 12-oz and comes with a nylon carrying case.
Comments about Champion Sports Weighted Training Softball Set:
Was expecting more from this item. This is probably good for beginners to get in shape but for competitive athletes only 1 of the balls was slightly effective. I would only recommend this to girls just starting out in softball to build their strength, not girls that have been playing a long time
