Sit in a chair with your feet dangling, not touching the floor. Grip the sides of the chair for support and slowly extend your left leg so it's almost completely straight, tightening the thigh muscle with your foot pointed toward the ceiling. Pause for five seconds and then slowly flex your knee to return to the starting position. Repeat with your right knee. Do two or three sets of 10.
