What is Muscle Confusion?
“Muscle Confusion” is the core philosophy behind the P90X workout. Results from traditional fitness programs diminish over time because our body adapts to the routine — a phenomenon called the “plateau effect”.
The P90X fitness system taps into the powerful training science of muscle confusion. As your body changes during the 90 day workout program, so do the routines.
By constantly introducing new workouts and exercises, each stage of P90X becomes as effective as the first.
