In 2004 Beachbody released P90X, Tony Horton's infamously tough and results oriented workout. The workout has gone to receive national acclaim and incredible success, with over 2 million people using it and constant, round the clock media coverage as pro athletes, celebrities, military officers and politicians promote their success with this program. Tony hasn't been resting on his laurels, however; during the last 6 years he's been working at improving his workouts, at designing new and more rigorous training exercises, all of which is culminating in a new workout slated to be released in 2011: P90X MC2 (Muscle Confusion 2).
