P90X, or Power 90 Extreme, is a home exercise system developed by Tony Horton in conjunction with Beachbody CEO Carl Daikeler, Beachbody Fitness Advisor Steve Edwards, nutritionist Carrie Wyatt, Creative Director Ned Farr, and workout video director Mason Bendewald of MEGA MACE productions. It claims to significantly improve physical fitness in 90 days through a rigorous segmented training program combined with a nutrition and dietary supplement plan.
P90X's advertising emphasizes "muscle confusion", a method of cross-training and periodization achieved through switching the order of exercises and incorporating new and varied movements.[1] Muscle confusion supposedly prevents the body from adapting to exercises over time, resulting in continual improvement without plateaus
