Instructions: How To

The Medicine Ball Leg Crunch is an exercise that targets your abdominal muscles. Lie on your back with your legs raised and knees slightly bent. Hold a medicine ball between your feet. Crunch your upper body and legs toward each other, squeezing the medicine ball between your feet.

  1. Lie face up on the floor and position a medicine ball between your knees.
  2. Raise your heels off the ground while squeezing the medicine ball with your knees. There should be a 90-degree bend in both your hips and knees.
  3. Engage your core to raise your shoulder blades off the ground.
  4. Hold this position for a moment at the top of the movement while maintaining tension in your core.
  5. Slowly allow your shoulder blades to descend back to the starting position while maintaining tension in your core.
  6. Maintain good posture by keeping the medicine ball secured between your knees, your core engaged and your hips and knees at 90-degree bends.
  7. You should feel this exercise in your core.
