The Swing Ball Pro is specially designed to improve core rotational strength. The patented slots and handles allow you to hold the weighted ball lightly and swing without tension, which is essential for releasing the golf club for maximum club head speed.
The two colors represent both sides of your body to help you balance the force generated from your left and right sides through the golf ball. The center reference represents the golf ball. Alternating grips will promote either draw or fade motions.
