1. Straight Leg Lift (lying down)
Lie down flat on your back with one knee bent and the other leg extended straight on the floor.
In the straight leg, tighten the quadriceps (thigh muscle) and raise it to about 45 degrees to the floor.
Hold at this angle for 2-3 seconds and then slowly lower it to the ground.
Repeat 15 times and switch legs.

2. Straight Leg Lift (Sitting)
Sit well in a chair with back support.
Straighten one leg and hold for a count to 10. Then slowly release your leg.
Repeat this atleast 10 times for each leg.
As you improve, try the exercise with light weights tied on your ankle.

3. Leg Cross
Sit on the side of the bed or on a chair. Cross your ankles over.
Push your front leg backwards and back leg forwards against each other until your thigh muscles become tense.
Hold for 10 seconds, then relax.
Switch legs and repeat. Do four sets with each leg.

4. Knee Straightening/Stretch
In lying down position, place a rolled up towel under your ankle. Bend the other leg at the knee.
Use the muscles of the straight leg to push the back of the knee firmly towards the bed.
