The split squat is a great full lower body exercise. Those who have mastered
the split squat and are looking for resistance can simply hold dumbbells or in
this case a medicine ball. By extending your arms with the weighted medicine
ball you work your anterior deltoids as well as increase the demand on the core
muscles which stabilize your torso. The stability ball squat medicine ball
extension can be performed with the shoulder extension on either the downward or
upward portion of the split squat.
