Crunch Form is Key
To get good results from your abdominal crunches, you want to make sure you're working the abs with proper form.
- At the start of each curl, tighten your stomach muscles FIRST, then slowly lift your torso upward.
- Let the top section of your abdominal muscles -- and not any other part of your upper body -- do the lifting.
Remember also that you're not looking for dramatic movement here. You want to curl forward slowly until your shoulder blades are lifted off the floor. If your torso is going much farther than that, you're not working your ab muscles properly (and you could wind up with back pain).
