Crunch – Exercise Ball

  1. Sit on the exercise ball and walk your feet forward until your lower back is supported by the ball, forming a 90-degree angle with your knees.
  2. Place your hands behind your head (without pulling on the neck) or across your chest.
  3. Exhale and contract your abs to lift your upper torso off the ball, focusing on bringing your ribs toward your hips.
  4. Inhale and slowly lower back, maintaining tension in the abdominals.
  5. Keep your lower body still, using your feet to maintain balance.
  6. Repeat the movement for your desired number of repetitions.
