Sit in chair. Extend legs, heels to floor. Keep knees straight (or as straight as possible if you have arthritis.) Tighten thigh muscles. Hold for count of 10. Relax for count of 3. Do 10 repetitions. You can do this several times throughout the day. You can build up to 2 or 3 sets of 10 repetitions at a time.

Lie flat on back. Bend left knee at 90-degree angle, keeping foot flat on floor. Keeping the right leg straight, slowly lift it to the height of the left knee. Hold for a count of 3. Repeat 10 times. Switch sides. Work up to 10 sets of 10 over several weeks.

Safety Tip:

Lifting both legs at the same time causes excessive stress on your lower back so only lift one leg at a time; the opposite leg should be kept slightly bent with foot on floor.

Sit or lie on floor. Place a rolled up towel under your thigh for support. Keep you leg straight and raise your foot about six inches off the floor. Hold for 5 seconds. Slowly lower your foot, bending your knee. Do 10 repetitions. Switch sides.
