Crunch (on stability ball)

Crunch (on stability ball)

The crunch on stability ball is a fantastic exercise that targets your abdominal muscles, specifically the rectus abdominis, obliques, and transverse abdominis. This variation of the traditional crunch adds an element of instability, engaging your core muscles even more. To perform the crunch on stability ball, you will need a stability ball and a flat surface. Start by positioning the stability ball under your lower back, ensuring that your feet are firmly planted on the ground, hip-width apart. Place your hands gently behind your head or crossed over your chest, whichever is more comfortable for you. Engage your core by pulling your belly button towards your spine and contracting your abdominals. Slowly curl your upper body off the ball, lifting your shoulder blades off the surface while keeping your lower back in contact with the ball. Exhale as you crunch up and contract your abs, and then inhale as you lower back down in a controlled manner. As with any exercise, it is crucial to maintain proper form and technique. Avoid pulling on your neck, as this can strain your neck and upper back. Focus on using your abdominal muscles to initiate the movement rather than relying on momentum. Incorporating the crunch on stability ball into your workout routine can help strengthen your core, improve posture, and enhance overall stability. Remember, proper nutrition and a well-rounded fitness routine are key components to reaching your fitness goals. So, be sure to complement this exercise with a balanced diet and plenty of cardiovascular and strength training exercises.


  • Start by sitting on the stability ball with your feet flat on the floor and your knees bent at a 90-degree angle.
  • Walk your feet forward, allowing the stability ball to roll underneath your lower back until your hips, knees, and shoulders are in a straight line.
  • Place your hands behind your head, with your elbows pointing out to the sides.
  • Engage your core muscles by drawing your belly button towards your spine.
  • Exhale and slowly curl your upper body forward, lifting your shoulder blades off the stability ball.
  • Inhale and gradually lower your upper body back down until your shoulder blades touch the stability ball.
  • Repeat for the desired number of repetitions, maintaining proper form and control throughout the exercise.
