The option to work out from home might be enticing

For stay-at-home moms or for those who work from home, perhaps as independent contractors, the option of working out at the comfort of one's living room might sound alluring.

If you're looking for DVD workouts P90x seems to be one of the more heavily marketed at-home workout programs. You can see the late-night infomercials that really talk up this product's potential, though it essentially seems to be very similar to the other video and DVD fitness programs you see out there. This set has 12 workouts, which some say can be too elementary to meet most needs.
