HOW: Stagger your feet by placing one foot slightly forward, making sure that your feet are about shoulder width apart. Then, completely sit down on the box in a controlled manner with good squat form. Then stand back up.
FEEL: You should feel the muscles in the legs working, but the forward leg will be working less.
COMPENSATION: Try to avoid shifting your hips side-to-side. Try your best not to fall into the chair. Try to control yourself as your lower into the chair. Do not use momentum to stand up, if able.
