Replace forward crunches with reverse crunches.
Do these by laying on the floor with your legs up in the air and your knees bent at about 90 degrees.
Make sure the lower part of your legs are parallel to the floor.
Then bring your knees back to touch your chest and forward again.
2) Do crunches on an exercise ball.
