Technique
How to do the Crunch (Stability Ball)
- Begin by sitting on a stability ball with your feet flat on the floor and your knees bent at a 90-degree angle.
- Walk your feet forward and lean back to position your lower and mid-back on the stability ball. Your upper body should be supported by the ball. Place your hands behind your head with your elbows pointing out to the sides.
- Engage your core and lift your shoulder blades upwards, curling your upper body towards your knees.
- Lower your shoulder blades back down with control, maintaining your core engagement. Repeat the movement for the desired number of repetitions.
Form cues
Getting it right
- Avoid pulling on your neck with your hands; focus on using your abdominal muscles to lift your shoulders.
- Ensure your lower back remains in contact with the stability ball to avoid unnecessary strain.
- Breathe steadily throughout the exercise, exhaling as you lift your shoulders and inhaling as you lower them.
