P90X is one of the top homework "systems" out on the market right now, but there's something that makes it different from the rest of the competition.
You don't get a "rah-rah" cheesy dance type workout here, P90X is about getting to work with some of the most basic exercises you've ever seen. Push-ups, pull-ups, squats, curls, all the things you're taught in school to become healthy. It's a top quality workout delivered in a simple package.
