How to do it: Stand with your feet wider than shoulder-width apart and toes pointing out at a 45-degree angle, your hands on your hips [A]. Bend your knees, extending your arms out in front of you for balance and lower your body until your thighs are parallel to the ground [B]. Push through your heels to return to the starting position. Repeat.
Tip: If you cannot move that far down, don't worry. Only lower your body as far as what's comfortable.
