(Used) Club K Weighted Ball Set & Spin Right Spinner

This gently used set of three balls comes in a vinyl carrying case and includes a regulation size softball (6.5 oz), a light softball (5.5 oz.), and a heavy softball (8.5 oz.). The training set includes an 8 week workout that is designed to increase speed. The ball seams are colored to help make weight identification easier. The Weighted Balls can be used within the workout or by themselves to improve strength, speed, wrist, snap and quickness. This also comes with the 8 week workout sheet by renowned pitching instructor, Cheri Kempf. Included in this purchase is a Spin Right Spinner to help your pitcher work on spins. Developed by Cheri Kempf of Club K, the disc provides instant feedback to the pitcher and instructor. Two factors help a pitch move: direction of spin and the speed of that spin. The Spin Right Spinner lets you work on both. Grip it one way to work on proper topspin, backspin or sidespin, depending on the pitch. Grip it another way to work on the speed of the spin. I use it hundreds of ways including self tosses, half tosses to catcher, stationary drill, 75% speed working up to 100% full motion from the full distance.
