Has anybody heard or tried this workout machine called ROM? I have seen it advertised in magazines and other places over the last few years. It looks like the time machine from the H. G. Wells classic. They claim you only need to do a 4-minute a day workout on it. The cost of the contraption is like $15,000. It sounds like it is competing with 7 min abs. I find it hard to believe that anybody can get any kind of health benefit from 4 to 7 min exercising.
