Stand tall with your feet approximately hip-width apart and weight distributed evenly between your feet. The loop of an exercise band is placed around your legs under your knees and the slack is taken off.
Bend your knees and hips as if you were sitting down. At the same time rotate your knees outwards against the resistance. The knees and toes should point in the same direction.
Push back up to the starting position using your front thighs and buttock muscles.
