- Lying on your back with your knee straight, attempt to contract your quad muscles (muscles on front of your thigh) for 5 seconds as strongly as possible.
- When contracting your quad muscles, your knee should dive down towards the ground.
- Repeat 10 times, 3-5 times per day.
Remember: Use caution and consult your physician, physical therapist, or athletic trainer if you're unsure about your exercises. Do not push into sharp or stabbing pain.
