The Ab Doer Twist ($200) was invented by John Abdo (Ab-do, no joke), and the website claims 3 million were sold around the world. If you haven't seen on the infomercials, The Ab Doer Twist is a chair with a bar at shoulder length, allowing you to 'twist your way into shape'.
The science: The Ab Doer Twist allows you to have a 360 degree ab workout all while providing aerobic training at the same time. Being seated means you're supported, stable, and aligned – allowing for an exhilarating workout in just minutes per day.
Our Verdict: Get fit, while you sit, smile, and watch TV? I don't (nor won't) buy it. And in my view, isolating the abdominals is not the best start for those starting their fitness journey.
I never believed that people would be so fucking dumb and uneducated about shit like this then my parents went ahead and bought an Ab Circle Pro
