This exercise works on balance, hip stabilization, core, and leg strength. This is an advanced exercise and can also be done without the jumps.
- Lie supine (belly up), arms at side, with one foot placed on the ball while the other leg reaches up to the sky. Hips are off the ground and abdominals are pulled in to support the back.
- The leg on the ball straightens then bends, pulling the ball toward the body; this completes one rep on one leg.
- After one rep, switch legs by pushing off the ball with a little jump as you bring other leg onto the ball.
Continue to alternate legs until they fatigue, about six to eight times each leg.
Editor's note: practice the jump beforehand with your exercise ball in the corner to create some stability.
