Yoga Ball Overhead Sit Up + Russian Twist

Tutorial

1. 1
   Sit on a mat and place the yoga ball in front of you. Your knees are bent and your feet are firmly on the floor.
2. 2
   Hold the yoga ball above your head with both hands. Your arms should be stretched, but not overstretched. The ball should rest securely in your hands.
3. 3
   Lean your upper body back slightly so that your back remains in an upright, neutral position.
4. 4
   Tighten your abdominal muscles and continue to hold the ball above your head. Keep your arms outstretched throughout the movement.
5. 5
   Lie on your back slowly and in a controlled manner, keeping the ball above your head. Keep your abdominal muscles tensed to support your back.
6. 6
   Lower your upper body in a controlled manner to just before the floor without putting the ball or your head down.
7. 7
   Use your abdominal muscles to straighten up into an upright position. The ball remains above your head. Avoid momentum and control the movement to maximize your abdominal muscles.
8. 8
   After you have completed the sit-up, hold the upright sitting position and lower the ball slightly forwards so that it hovers in the air in front of your chest.
9. 9
   Turn your upper body to the right as you move the ball to the side in a controlled manner. Make sure that your hips remain stable and that the rotation comes from the center of your body.
10. 10
    Return to the center and repeat the movement to the left side. This counts as one complete repetition.
