The Elite System for Strength, Fitness, and Incremental Velocity Gains.

In the modern era of high-velocity pitching, arm care is no longer optional—it is a requirement. DST and AceSportz have combined their expertise to develop PlyoBallz: the highest quality throwing training tools designed to build explosive arm strength and elite fitness. This isn't just a set of weighted balls; it is a professional-grade training system that incorporates an expanded range of weights, allowing for a more measured and controlled approach to arm development.

WHY PLYOBALLZ ARE THE INDUSTRY STANDARD:

1. The DST x AceSportz Engineering Partnership

When the best in the game collaborate, the result is unmatched quality. DST and AceSportz have partnered to create a product line that bridges the gap between raw throwing and scientific arm care. These PlyoBallz are the foundation of comprehensive arm care programs, trusted by athletes across all skill levels to build the resilience needed for a full season of high-performance play.

2. Measured Incremental Resistance

The secret to safe velocity gains is the "Controlled Ramp." Most weighted ball programs fail because the weight jumps are too extreme, putting unnecessary stress on the elbow and shoulder. Our expanded range of ball weights allows for precise, incremental resistance. By increasing the load in small, measured steps, the arm is forced to gradually adjust and compensate, building strength in the healthiest way possible.

3. Professional Weight Versatility

No two arms are the same, and no two training days should be identical. Our wide range of weights—from the ultra-light 3.5oz to the heavy-duty 24oz—ensures that pitchers of any age can gain strength safely. Whether you are working on recovery, mechanics, or peak power, you have the exact weight needed to optimize your specific training protocol.

4. Build Strength Through Arm Fitness

PlyoBallz are designed to improve the overall "fitness" of the arm. By incorporating these into a daily routine, players develop the stabilizer muscles required to handle the torque of a competitive delivery. It is the perfect way to increase arm strength and endurance while prioritizing the long-term health of the athlete.
