Targets: Butt and hamstrings
Lie faceup on floor, arms by sides, palms down, with right heel resting on stability ball and left knee bent in toward chest, shin parallel to floor.
- Dig right heel into stability ball and bend right knee to 90 degrees to lift hips off floor and roll ball toward you. (MAKE IT EASIER: Keep both heels on ball to roll it toward you, or rest heels on a bench and press hips up.)
- Slowly lower as you extend right leg to start position.
- Do 10 reps. Switch sides, repeat.
Tip: The more slowly you roll the ball with your leg, the more this move will tighten that just-below-the behind jiggle.
