Place your hands behind your head, making sure not to pull on your neck, and keep your elbows wide.
Engage your core and lift your upper body towards your knees, crunching your abs.
Slowly lower your body back down to the starting position, maintaining control and not letting the ball roll.
Repeat this movement for the desired number of repetitions, ensuring to keep your core engaged throughout the exercise.
Pro Tip
Controlled Movement: Avoid fast, jerky movements. Instead, focus on slow, controlled movements. This will not only help avoid injury, but also ensure that your muscles are being properly engaged. When you crunch up, exhale and contract your abs, hold for a second, then slowly lower yourself back down while inhaling. Range of Motion: A common mistake is not using the full range of motion. Make sure to fully extend your back over the ball at the start of the movement, and then crunch up until your upper body is perpendicular to the floor. This will maximize the effectiveness of the exercise. Keep Your Neck Relaxed: Avoid pulling on your neck or head as you crunch up.
