Begin this exercise facing a smooth reinforced wall with the Dynamax ball off of one hip.
Initiate the movement by pushing the hips back while slightly flexing at the knees and ankles.
In one powerful movement extend the ankles, knees, and hips while simultaneously performing a unilateral underhand throw (bowl) toward the wall on a slightly higher than horizontal plane.
Catch the rebound and immediately perform the underhand throw off the opposite hip.
