Holding a single-leg bridge will work your booty, but your abs will kick into gear to stabilize your torso while you kick.
- Start in a bridge position with your hands by your sides.
- Lift your left foot off the floor, straightening your knee but keeping your thighs parallel.
- Kick your left leg up, so the sole of your flexed foot is toward the ceiling.
- Without letting the pelvis drop, slowly lower your left leg so your thighs are even. This completes one rep.
- Do five reps on each leg to start.
