Description

The crunch on a stability ball with arms straight is an advanced abdominal exercise that targets the core muscles while also engaging the stabilizing muscles.

Starting Position

Sit on the stability ball with your feet flat on the floor, lower back supported by the ball, and arms extended straight above your head.

Technical Execution

Exhale as you engage your core to lift your torso towards your thighs, keeping the arms straight overhead. Inhale as you lower back down with control.

Range of Motion

Focus on a controlled range of motion, aiming to bring your shoulder blades off the ball while maintaining the stability of the rest of your body.

Variations

To increase difficulty, you can hold a light weight plate or medicine ball in your hands while performing the crunches.

Common Mistakes

Common mistakes include using momentum instead of engaging the core, placing too much strain on the neck, and not maintaining proper form throughout the movement.

Practical Advice

Focus on contracting the abs to lift the torso, keep the neck in a neutral position, and use controlled movements to maximize the effectiveness of the exercise.

Additional Notes

Ensure the stability ball is properly inflated and positioned to provide stability while allowing for a full range of motion during the crunches.
