This Ab wheel does work, but I want to emphasize that you must use good form. I found it helpful to press my feet up against the wall to help steady myself as I pushed out with my arms. Don't try to go too far out when first beginning to use the Ab wheel. It does require some patience as you get your flow. What I like about this Ab wheel is you don't have put anything together - no handle coverings. My boyfriend loves it and he has a six pack.
