How Does P90X Work?

P90X is marketed as an advanced home-training fitness system, designed by Beach Body fitness program's expert trainer, Tony Horton. The key to the system's results is the use of a training technique called Muscle Confusion that is designed to accelerate typical fitness routine results.

Function

• The Muscle Confusion technique operates on the theory that using the same workout routine regularly is ineffective. Build Muscle Guide notes that with repetition, muscles quickly get used to the workout and plateau, slowing results. Horton's P90X comes with 12 different workouts to continually vary the routine, thereby challenging the body in new ways and preventing plateaus.

Features

• In addition to using Muscle Confusion to accelerate fitness results, P90X's 12 routines are designed to motivate the individual to stay on a daily workout schedule. P90X sells the concept of variety as an added incentive to prevent boredom and keep the client motivated to work out.

Misconceptions

• Horton's P90X plan markets the Muscle Confusion technique as the key to achieving fitness results, but that technique alone does not deliver results. The P90X family of programs also includes a strict nutritional plan. To achieve the advertised accelerated results, the client must adhere strictly to both the workout plan and the nutritional plan for the full 90 days.
