I read about this site in RealSimple magazine a few months ago, and I went to check it out yesterday. It's a site meant to help you be active throughout the day - it pops up on your computer every 30 minutes and leads you through a 3-minute workout. Apparently it's based on martial arts - one of the comments on the site said it was like Tai Chi on fast-forward, so there's no jumping or anything high-impact but it does get your heart rate up. Obviously, it's intended to play on the idea that exercise is cumulative. If you actually did the 3-minute workouts every 30 minutes for an entire workday, they claim it's equivalent to spending 45 minutes at the gym before or after work, and it gets you out of your chair during the day (which I *know* is good for you).

My problem is that there is no video demo, no free trial, nothing so you can actually see what the exercises look like. Which makes me quite skeptical, but on the other hand, a major magazine like RealSimple recommended it. It's $20 to get the low-price version, which has something like 5 exercises in it, and I think $50 or $60 to get the full verison with 27 exercises. So - has anybody taken the plunge and tried this? Is it worth it? Would you actually do it or are the exercises dumb?
