- Stand upright with your back against a wall and feet shoulder-width apart.
- Slowly bend your knees, sliding your back down the wall for a count of five until your knees are bent at a 45-degree angle. (Do not bend too much further than this, as it will cause increased strain on your knees.) Hold this position for 5 seconds.
- Begin straightening your knees for a count of five, sliding up the wall until you are fully upright with knees straight.
- Repeat the above steps 10 more times.
