Stand with your feet shoulder-width apart, toes pointing slightly outward.
Place a theraband around your thighs, just above your knees. Make sure it is secure but not overly tight.
Engage your core and keep your chest lifted and back straight.
Begin the movement by pushing your hips back as if sitting into a chair, while bending your knees.
Focus on pressing your knees outward against the band to keep them aligned directly over your toes, resisting the inward pull.
Lower yourself down until the height recommended by your Physiotherapist, or as far as is comfortable, ensuring your weight remains through your heels.
Push through your heels and squeeze your glutes as you rise back up to a standing position, maintaining the outward pressure on the band.
Complete repetitions as prescribed by your physiotherapist.
