Hold a pair of dumbbells directly over your shoulders, with your arms completely straight. Squeeze your abs tight for the entire exercise. (A) Stand in a staggered stance, your left foot in front of your right foot. (B) Push your hips back and bend your knees so you lower your body into a squat. Pause, then push yourself back up to the starting position. Perform the prescribed number of reps, and then do the same number of reps with your right foot in front of your left.
