Stability Ball Oblique Crunch
- Stability Ball
1) Lay on the stability ball - make sure your lower back has contact and your feet are fully planted on the floor. Place your hands behind your head.
1) Curl up by tightening the core. As you do this, twist the trunk so your left elbow is pointing towards the right knee.
2) Pause for a second and 'crunch' at the top - you'll feel this in your obliques. Now, slowly lower yourself to the starting position.
3) Repeat on the other side.
