One of the most popular workouts in the fitness world today is Tony Horton’s extreme workout DVD program, P90X.  It’s not your typical home or gym (if you’re smart enough to rip it on your iPod/iPhone) workout.   Every day is different.  One day could be an intense yoga session.   Other days could be arms and shoulders, legs, or even kempo.  Tony’s program is made to confuse the muscles so you don’t plateau, which gives you the results you see on your body.   Some celeberities have become avid P90Xers.   Ashton Kutcher and Demi Moore have even tweeted their P90X experience.
