As above, you will need a piece of rubber tubing or elastic band. Stand with the legs shoulder width apart, with the "good" leg closest to the furniture or door. The tubing should loop around the outside of the injured leg. Lift the affected leg to the side, 18 to 24 inches away from the body, stretching the tubing. Hold for 5 seconds, then slowly release. Rest as needed. Repeat 10 to 15 times (one set). Perform a total of 3 sets.
