Want to hit the ball farther? Bat speed and power come from the core area. Proper rotation is essential to achieve maximum distance. The CorePower SwingSnap Training™ App was engineered to teach proper core rotation in real time! When a player swings, the trainer makes 100's of measurements per second, monitoring core acceleration and rotation. When the core (hip) area is rotated properly a loud "SNAP" sound will be made. Use the app along with the training videos to develop a quick, compact, powerful baseball swing! 6w444h
