If your pushups & pullups are perfect, you might as well do some perfect hanging, reverse crunches.

Made with a thick padded lining and high-end fabrics, the Perfect Ab Straps are comfortable and designed for years of use. These heavy nylon straps attach to your Perfect Pullup bars using a mountaineering-grade steel carabineer.

This adds nothing to the description, but carabineer is one of my favorite words. Try it...carabineer.
