The Trunk Accelerator: Transforming Mechanics, Velocity, and Spin ⚾💥 The Trunk Accelerator is changing the game – not just improving pitching mechanics, but also boosting velocity and spin rates. Here’s why: ❌ The Problem Without It: • Many pitchers rely on pulling their arm back, forcing their arm to handle too much of the acceleration. • When the trunk rotates early, the arm is rushed, leading to inefficiency and less power. ✅ The Trunk Accelerator Effect: • Forces you to keep the trunk close
