The Four-Seam Throw Trainer helps young athletes enhance throwing technique by providing instant feedback on revolutions per minute (RPM) and grip guidance. Designed for players 12 and under, the set includes two softballs that match the size and weight of a standard softball. The striped ball turns purple when thrown with proper form at high RPMs, reinforcing correct arm angles. The white ball features a black rotation guide and raised seams to help develop a consistent grip and backspin. By building muscle memory through repetition, young athletes can refine their accuracy, arm strength, and throwing confidence for game-day success.
