The ROM has been around for a while (it won the "Best of What's New" award from Popular Science in 1991), but I've yet to see one hanging out in the cardio section at the gym. It could be the almost $15,000 price tag. Yeah, if you thought the Bowflex was expensive...
It does look intriguing though, and I wouldn't mind trying one. It's hard to work up excitment for the treadmill or elliptical trainer any more. The ROM is supposed to give you a complete workout in four minutes a day. The company says, "From 4 minutes on the ROM you get the same results as from 20 to 45 minutes aerobic exercise (jogging, running, etc.) for cardio and respiratory benefits, plus 45 minutes weight training for muscle tone and strength, plus 20 minutes stretching exercise for limberness/flexibility." Of course, the real question is how many calories does the sucker burn... Do they really think we ladies spent an hour on the stairmaster because of respiratory benefits? *snort*
Anyway, I digress. If it looks like something you're interested in, the company offers a free video over on their site if you want to check it out. (Nope, I don't make anything if you buy one. But if you do please come back and let us know how it goes.)
