How It Works

P90X is a set of 12 high-intensity DVD workouts that you do over the course of 90 days. You've probably seen the infomercials about it on TV.

You'll commit to working out 6-7 days per week, for 1-1.5 hours at a time.

The DVDs keep you moving from exercise to exercise, like circuit training. Some of the DVDs focus on strength. Others include plyometrics (explosive "power" moves), kickboxing, cardio, abs/core, and yoga. The plan also includes a fitness guide and nutrition plan.

Your muscles will get stronger, you’ll boost your cardio health, and you’ll shed fat on this plan designed and led by celebrity trainer Tony Horton.

With any program that's this tough, there's a chance of injury. It may be too much for you if you're not active now or if you have certain conditions, so check with your doctor first.
