How: Stand on the one leg and hold your walker or a surface for support. Move your other leg out to your side, keeping your toes forward. Do not rotate your leg or lean to the side. Hold for 5 to 10 seconds if able.
How often: Work up to 10 reps, 3 times a day. This is a more advanced exercise. If you find it too difficult, continue doing the version of it lying down instead until you feel stronger.
