The p90x system is an intense home DVD exercise program that says it can give you a lean, ripped body in 90 days. But it's not for the faint of heart -- or the very out of shape. Getting fit the P90X way means working out 6-7 days per week, with each workout lasting about 1-1½ hours. And the workouts are so rigorous that you're asked to take a fitness test before ordering the P90X system, to see whether you're up to the challenge. What exactly is the P90X system? For $119.85 (made in three payments of $39.95 each), you get 12 workout DVDs, a 100-page fitness guide, a 113-page nutrition plan, and a 90-day calendar to track your progress. (You'll need some additional equipment -- a pull-up bar, dumbbells, resistance bands, and an exercise mat.) The P90X workout system is sold by Beach Body through its web site and via television infomercials. Beach Body offers a 100%, 90-day satisfaction guarantee, though you'll still have to pay shipping costs if you end up returning the P90X system.
