When should i start p90x?

You need to learn the difference between weight and fat. P90X is a very good program for burning fat, which makes you weigh less. It will also put some muscle on you, which makes you weigh more. So if you lost ten pounds of fat, and gained ten pounds of muscle, you'd weigh the same. But you'd look a hell of a lot better. So no, P90X won't help you lose much weight, but in this case that's a good thing.  more
