Preparation: Lie on your back and place your arms at your sides with your palms facing the floor. Grasp the ball between your calves with your legs extended.
Breathing: Inhale to grasp the ball, exhale after exercise.
Execution: Grasp the ball with your calves, inhale and lift the ball off the floor. Clench your legs together so that you are holding the ball with the back of your legs. Slowly bring your thighs up towards your chest. Hold for a second and return to the starting position and repeat.
