P90X was developed to leverage muscle confusion. Muscle confusion changes up the movements your body is used to doing, to get you incredible results. Typical training causes your body to plateau and stop seeing results. Your body adapts, and the weight loss stops, or the muscle growth stops. With P90X this doesn’t happen.
P90X2 introduced a concept of muscle integration. Muscle integration was a breakthrough in applied sports science. By packing P90X2 with movements that forced you to use multiple muscles in your body at the same time, P90X2 delivers a workout usually reserved for professional athletes. It also leverages muscle confusion from the original P90X series.
P90X3 adds a concept known as muscle acceleration. Muscle acceleration introduces intense workouts for 30 minutes, with tiny 30 second breaks. This makes you work at an accelerated pace during a shorter period of time. The latest fitness science has found that people achieve most of their results during the first 30 minutes of a workout. Add to P90X3 muscle confusion, as well as muscle integration training, and you have yourself the ultimate version of P90X. P90X3 has arrived.
