This exercise strengthens the hamstrings and lower abdominals and also gives the booty a nice lift!
- Starting position: lie supine (belly up) with arms down by sides, both feet placed on the ball with knees bent. Belly is pulled in, and reach long through the tailbone to lift the hips off the ground.
- Straighten legs, rolling ball away from you.
- Bend knees to pull the ball back toward pelvis. This counts as one rep.
Do eight to 12 repetitions, then lower spine back to the ground.
