Lift Your Lower Half With a Booty-Shaping Circuit Workout

• Begin standing, and place right foot on six- to 12-pound SandBell (if you don't have a SandBell, use a paper plate on carpet or a towel on hardwood floors).
• Squat at your left knee, and simultaneously slide right leg out to the side. Drag your right leg in with control, and return to standing. This completes one rep.
• Repeat for 12 reps, then switch sides.
