They help you tone the ab area...but as you already know, you need to get rid of the flab covering the abs before they begin to show. Spot reduction is a myth.

Personally, I got absolutely nothing from the ab roller in the abs!! I tried concentrating so hard, yu know, mind into muscle. I always felt so much more in my shoulders and back. On the other hand, I know people who swear by them. You will probably have to find out for yourself on that one.
