Sculpt your legs, butt, and hips while slimming your waist with this double-duty move.
How to do it: Stand tall with your feet slightly wider than hip width, toes and knees turned out about 45 degrees, hands behind your head. Bend your knees and lower into a sumo squat (dropping hips as low as you can without letting knees buckle forward or back).
As you press back up to standing, raise your right knee up toward your right elbow and do a side crunch with your torso to the right. Step your right foot down and immediately repeat sumo squat and crunch to the left. Repeat, alternating sides each time, for 1 minute.
