Do you want your lower abs to suffer just as much as the rest? Then look no further than this Ab roller with foot straps. It allows you to do Ab roll outs of the lower abs, which are much harder than they sound. The axle in it will bend if you out too much pressure on it during the roll out, but that might only be for 200lb+ individuals. I think the tubing might be designed to go behind your heel? The straps themselves work fine.
