Lateral Leg Lift

With your hands on your hips and your feet hip-width apart, bend your knees to lower into a squat. Pause, then stand and lift your right leg out to the side as high as you can. Return to start. That's one rep. Repeat with the left leg, and continue alternating until you've done 12 to 15 reps on each side.

Lateral Shuffle

Stand with your feet hip-width apart, knees bent, chest upright, and elbows bent at a 90-degree angle. Take a wide step to the left, then quickly bring your right foot to meet your left. Then switch directions, stepping your right foot out to the side. Continue going back and forth.
