If the plank crunch on the stability ball was not challenging enough, try the stability ball rotating side crunch. A similar exercise… with a twist!
HOW TO…
- Again, get in a High Plank position with your feet on the stability ball.
- Start rotating your hips to the side until your pelvis is facing sideways.
- While rotating, pull up your knees a little bit for the crunch movement. Your lower leg is resting on the ball, with the upper leg resting on the lower leg.
- In this exercise, you cannot move the legs up too far, as you will lose balance easily. Anything up to 90 degrees between the upper body and the knees is fine.
- Keep the position for 2 seconds and then move the ball back again. Push with your feet and rotate your hips back in line with your shoulders until you are in a full high plank again.
- This completes the stability ball rotating side crunch. Repeat on the other side.
Note: Although the picture has me looking sideways, in the direction of the rotation, it is perfectly fine to keep looking downward.
Goal: Try to repeat the stability ball plank crunch 5 times on each side before moving off the ball.
Variation: You can build up to this exercise by first starting the rotation only. Add the crunch once you are comfortable rotating on your side with your legs on the ball.
