The promise: "With Ab Rocket, you don't need any expensive gym memberships to get the body you have always wanted. Simply use Ab Rocket for five minutes a day, and you will be able to transform your body with toned, sizzling rock-hard abs that will amaze your friends!"
How it works: Supposedly, you'll "get a complete ab workout" and "melt away the fat" just by rocking back and forth in this awkward blue chair, which allegedly feels like a "soothing massage."
The verdict: Okay, now we're talking! Any workout that you can perform while drinking a beer is a winner in my book. But alas, after thoroughly investigating, I still have no idea where the "rocket" part comes in. And after rocking for a month in a metal chair that looks like it belongs in a gynecologist's office (or at least how I imagine a chair in a gynecologist's office would look), I still don't have a six-pack. Bottom line: Why not just, oh, I don't know... do some sit-ups? Pass.
