Underload Baseball Training Set — Weighted Baseball Set for Pitcher Arm Speed & Velocity Development
The Velocity Weighted Training Baseball Set is the ultimate tool for athletes looking to add miles per hour to their fastball. By incorporating both underload (3oz/4oz) and slight overload (6oz) training, pitchers can break through velocity plateaus. Underload training helps the brain and muscles adapt to faster movement patterns, while the slightly heavier 6oz ball builds the stabilizing strength required for a high-velocity finish. The striped design provides instant visual feedback. Whether you are working on a 4-seam “rise” or a sharp-breaking slider, the stripes allow you to see the exact tilt and efficiency of your spin. Every ball in this set is wrapped in a rugged Durahide cover, ensuring it can handle the intensity of daily weighted-ball routines. From plyometric drills to flat-ground sessions, this set is designed to be a staple in your pitching program.
