Crunch (On Stability Ball)

1. Sit on the stability ball and walk your feet forward until your lower back is resting comfortably on the ball. 2. Place your hands lightly behind your ears with your elbows pointing out to the sides. 3. Engage your core muscles and lift your upper body slightly off the ball, curling your torso towards your hips. 4. Exhale as you perform the crunch and focus on contracting your abdominal muscles. 5. Pause briefly at the top of the movement, then slowly lower your upper body back down to the starting position. 6. Repeat for the desired number of repetitions, maintaining control and stability throughout the exercise. Remember to always consult with a qualified professional before starting any new exercise routine, and listen to your body, only performing exercises within your comfort level.
