This move is fantastic because all you need is a wall! Be sure to find your center of balance before beginning this move, and try to complete 15 reps. "Lean your back against a sturdy wall, with your feet planted 1-2 feet in front of you. Bend the knees to squat down and straighten them to push back up. Keep the abs engaged, your back straight, and your weight in your heels. Make sure your knees don't go past your toes. Exhale as you stand back up and inhale as you lower down."
