You may have seen the infomercials for Tony Horton’s P90X or heard about it from a friend or coworker, but you may not know what exactly the workout is all about. P90X is a revolutionary»

We can’t install a pull-up bar in our apartment but really want to do the PX90 workouts. Is it a waste of money if we can’t use the bar?
I mean P90X. :)
