Ab Crunch with Ball Lumbar Support
Strengthens the abdominal muscles

Exercise mat, rubber or plastic ball. Another option is to use a medicine ball.

Exercise technique:

  1. Sit down with knees bent. Place the ball behind your lower back and lean back against it until your body is in an inclined position.
  2. Hold your arms in front of you at shoulder level with your palms facing each other.
  3. Contract your abdominal muscles and slightly curl your upper body while maintaining contact with the ball.
  4. Return to starting position.

Performance tips:

  1. Exhale as you curl forward; inhale as you return to starting point.
  2. Consciously contract your abdominal muscles to initiate the curl rather than just propelling your upper body forward. As you contract your abs, press your lower back into the ball.
  3. Maintain contact between your lower back and the ball throughout the exercise.


Do 5-10 repetitions.
