Leg Raises
While sitting on the edge of the bed or in a chair, raise one leg and extend out in front of you. Now raise it a little higher and hold for a thirty count. Now do the other one.
Then, clasp your hands under one leg just above the knee for support and raise your lower leg 30 times. Now do the other one. Finally, raise one leg up and rotate the foot around 15 times in each direction. Now do the other one.
