Champro Weighted Baseball Training Sets provide 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. The progressively heavier balls in these sets can help athletes work on building arm strength and throwing velocity. Champro’s weighted training baseballs have stripe patterns that allow pitchers to monitor the pitch rotation, helping them develop their skill set. These balls also have raised seams and durahide covers that are made to last. Weighted balls should not be hit with a bat or thrown to another player. They should only be thrown into screens or used for stretching exercises.
