Work your lower back with this fun super man exercise

Description

Alternating your legs and arms on a stability ball will help you with coordination and stability. It is not as easy as it looks. Try to stay slow and precise. It will work your lower back, upper back, your thighs and gluts (buttocks). Try getting a spotter when you do it the first time, since it is not as easy as it looks and you can fall off the ball.
