DESIGNED IN THE LAB. PROVEN ON THE FIELD.
The Driveline Difference
PlyoCare balls weren't sourced from a factory catalog. They were designed inside Driveline's training facilities, iterated based on athlete data, and refined across thousands of throwing sessions with professional, collegiate, and youth athletes.
The seamless surface is intentional — not a cost-saving measure. Seams trigger familiar neuromuscular patterns that these drills are specifically designed to re-pattern. Removing the seams removes the shortcut. Your body has to find a new, more efficient way to move.
Every design decision — the weight increments, the sand fill, the PVC rubber shell, the 2.85" diameter — was made to optimize a specific training outcome. Nothing about this ball is arbitrary.
