Moving Squat (targets quads, and outer thighs) Stand with feet together. Step right foot out to side 2 to 3 feet, bend hips and knees, and sit back as if lowering into a chair. Keep knees behind toes. Stand up, bringing left foot toward right so feet are together. Step to left on next rep. Alternate sides until you’ve completed all reps.
