Crunch (on stability ball, arms straight)

Crunch (on stability ball, arms straight)

The crunch on a stability ball with arms straight is an excellent exercise for targeting your abdominal muscles. This variation of the traditional crunch adds an extra challenge by incorporating the use of a stability ball, which enhances core stability and engages more muscles throughout your body. To perform this exercise, you will need a stability ball and a clear space to work out in. Start by sitting on the stability ball and slowly walk your feet forward, allowing the ball to roll underneath your lower back until your hips and knees are at a 90-degree angle. Keep your feet firmly planted on the ground, shoulder-width apart. Extend your arms straight above your head, keeping them in line with your body. This starting position will activate your entire abdominal region and prepare your core muscles for the movement. Now, contract your abs and begin to curl your upper body forward, lifting your shoulder blades off the stability ball. Focus on using your abdominal muscles to initiate the movement rather than relying on momentum. Exhale as you come up and inhale as you return to the starting position. Remember to maintain a strong core throughout the exercise, keeping your back in a neutral position and avoiding any excessive arching or rounding. Aim for controlled and deliberate movements rather than rushing through the exercise. By incorporating the stability ball and straightening your arms, you challenge your core stability further, engaging more muscles in your abdomen, including the rectus abdominis, obliques, and transverse abdominis. Keep in mind that proper form and technique are crucial to maximize the effectiveness of this exercise and minimize the risk of injury. Including the crunch on a stability ball with arms straight in your overall core workout routine will help strengthen your abs, improve your posture, and enhance your overall stability. Combine it with other exercises targeting different muscle groups to have a well-rounded fitness regimen.

  • Engage your core muscles by pulling your belly button in towards your spine
  • Begin the movement by slowly curling your upper body towards your thighs, lifting your shoulder blades off the ball
  • Exhale as you crunch and focus on contracting your abdominal muscles

Tips & Tricks
