Take it up a notch, and try this bridge variation to really tone your hamstrings and glutes.
- Lie on your back with your knees bent and feet about 12 inches from your butt. Put the ball under your feet.
- Exhale, press your feet into the ball to lift your pelvis, and come into a bridge, but do not overarch your back.
- Inhale, lowering your pelvis to the mat. Use your abs to keep the motion as smooth and controlled as possible.
- Do 15 reps to complete a set, and do at least two sets.
