Stand between handles facing away from fulcrum. Grasp both handles to sides and stand upright. Cross lower leg above knee of supporting leg.
Bend knee forward slightly while allowing hips to bend back behind, keeping back straight and knee pointed same direction of foot. Squat down as low as possible. Extend knee and hip until leg is straight. Return and repeat. Continue with opposite leg.
Range of motion will be improved with greater leg strength and glute flexibility. Base knee should point same direction as foot throughout movement.
