The PowerNet Weighted Training Balls are designed to help hitters drive the barrel through the ball following through completely. The weight of the ball helps in muscle memory development and gives you instant feedback on every contact swing. Instantly know mis-hits versus square hits. The balls have a limited flight letting you perform full swings in limited space and without using hitting nets. As the hitter gets stronger and their swing begins to easily accelerate through one weight, they can move up to the next weight class. Also great for warm-up tosses before throwing a real baseball or softball. Sold in a Pack of (9) Balls: Ball Size: 3.2"
