Technique

How to perform Stability Ball Crunch

1. Position your lower back on the stability ball with your feet planted and knees bent.
2. Cross your arms over your chest or keep them alongside your body, with the hips held steady.
3. Lower your upper torso back over the ball through a controlled range while the lower back remains supported.
4. Curl the rib cage toward the pelvis, lifting the shoulders without turning the movement into a full sit-up.
5. Let your head move with your upper torso rather than pulling it forward with the hands.
6. Lower under control to repeat, keeping the ball and feet steady.
