Movement overview

The Stability Ball Crunch is an effective core exercise that targets the abdominal muscles. By performing this exercise on a stability ball, you engage more muscle fibers and improve balance and coordination. This exercise primarily works the rectus abdominis, with secondary engagement of the obliques and transverse abdominis.

Step-by-step cues

1. Sit on a stability ball with your feet flat on the floor, hip-width apart.
2. Walk your feet forward and roll your back onto the ball until your lower back is supported and your thighs are parallel to the floor.
3. Place your hands behind your head with elbows wide, or cross them over your chest.
4. Engage your core by pulling your navel towards your spine.
5. Exhale as you lift your upper body off the ball, curling your shoulders towards your hips.
6. Pause at the top of the movement for a moment, ensuring maximum contraction of the abs.
7. Inhale as you slowly lower back down to the starting position, maintaining tension in your core.
8. Repeat for the desired number of repetitions.

Technical tips

• Ensure that the stability ball is properly inflated to maintain balance and effectiveness.
• Keep your feet firmly planted on the ground to prevent slipping during the exercise.
• Focus on using your abdominal muscles to lift rather than pulling on your neck or head.
• Maintain a slow and controlled motion throughout to maximize muscle engagement.
• Avoid arching your back excessively; keep it in a natural curve supported by the ball.
• Breathe out during the crunch phase and inhale as you return to the starting position.
• For increased difficulty, try extending your arms overhead or holding a weight plate across your chest.
