I first saw the Perfect Pushup in a late night infomercial, so i dismissed it. Is it good? What does it add to a standard pushup?
It doesn't look like it would be hard, but those stupid handles make pushups a real challenge. The rotation really brings your shoulders into play, if you rotate 180 degrees to do a punching like motion your biceps get a workout, and for some reason beyond my understanding your chest is smoked after a few sets. I've found that I can do roughly 3x as many regular pushups as I can do PP pushups. Like Mike said, not a mandatory piece of equipment by any stretch, but definitely a good investment if you like doing pushups (or are required to for PT tests).
