I did this program for about five months and was pleased to find that it actually did work, and it does feel good. You can lose weight on it (I lost about 10 pounds in 3-4 months) and it does develop you aerobically. (I found myself less out-of-breath when I exerted myself in whatever task I had on hand.) You can do as much as you like and as little as about 15 minutes a day, and this is a =real= 15 minutes, not an =exercise= 15 minutes, which normally doesn't include warming up, cooling down, showering, changing clothes, et cetera. Since the complete thing takes 15 minutes, doesn't require a warm-up or a cool-down, isn't likely to make you sweat, or even require work-out clothes, it's a good way to get some activity into your life. It's easy to do when injured, and probably even a good idea when sick in many cases, unlike most workouts. You can even do it in the car. Are there problems with it? Well, yes, you might find it very unpleasant to actually =do=. Intense breathing is not for everyone. (Some people compare it to yoga, but it's not at all meditative.) You're also not going to get the kind of muscles you'll get from the Body-for-LIFE program (for example) or the sort of weight-loss you might get from the Atkins diet. But ultimately, I'm glad to have this program in my exercise arsenal. It can give you an energy boost when you're stuck in traffic, give you a way to keep your aerobic level up after a long period of not exercising, and is definitely a worthwhile effort.
