Stand with feet hip width apart. Hold medicine ball with both hands in front of upper chest or face.
Squat down by bending knees and hips. Immediately squat up by extending hips, knees, and feet. Just before legs completely extend, begin to throw ball upward by extending arms upward. Jump up off ground, straighten arms, and release ball overhead. Land on both feet with legs slightly bent to absorb impact. Stand upright and catch ball as it falls back down.
Squat and Overhead Throw is considered full body movement. Dynamic spinal extension may occur in some individuals performing maximal attempts. Slight spine flexion may occur during bent over squat position dependent upon participants depth and flexibility. Also, spinal hyper-extension may occur as body extends and leaves ground.
