Setup
- Sit on the stability ball and walk your feet forward until your lower back is centered on the curve of the ball.
- Position your feet flat on the floor, hip-width apart, to create a stable base.
- Place your hands lightly behind your ears or cross them over your chest.
How to do it
- Inhale and lean back slightly to allow your spine to follow the contour of the ball, stretching the abdominals.
- Exhale and contract your abs to curl your upper torso upward, focusing on bringing your ribs toward your hips.
- Pause at the top for one second to maximize the peak contraction.
- Lower your upper body back to the starting position with a controlled 2-second tempo.
Form checklist
- Keep your lower back in constant contact with the ball throughout the movement.
- Avoid pulling on your head or neck with your hands.
- Maintain a slight gap between your chin and chest to keep the cervical spine neutral.
- Keep your hips and legs still to ensure the core is doing the work.
Pro tips
- Focus on the mind-muscle connection by visualizing your abs shortening as you lift rather than just moving your head up.
- Press your navel into the ball as you crunch to ensure deep transverse abdominis engagement.
Make it harder
- Hold a weight plate or medicine ball against your chest for added resistance.
- Extend your arms straight overhead to increase the lever length and difficulty.
