Knee Extension Exercise
Sit in a chair with your foot resting on a stool across from you and your knee slightly raised. Gently push the raised knee toward the floor using only your leg muscles. You will feel the top of your thigh get tight, and at the same time you will feel a stretch at the back of your knee. Hold for about 6 seconds, then relax for up to 10 seconds. Repeat 8 to 12 times.
