Rear Posture Board
The Rear Posture Board utilizes the Anti-Slide Wall for the purpose of maintaining a consistent spine angle throughout the swing.
When set up correctly the player's rear end should lightly touch the Rear Posture Board and stay in contact with it throughout the entire swing. By doing this, the hips will rotate properly and not allow the spine angle to straighten, especially during the downswing. Because the downswing happens so quickly it is difficult to feel when the hips move towards the ball, instead of staying in position.
