The Performax method looks at muscle involvement differently than is usual in the fitness industry.

Rather than automatically focusing on the industry standard muscles involved in the exercises, Performax seeks to normalize all muscles involved.

In the Seated ISO Ab "T," for example, Performax is interested in the trapezius, latissimus, and dorsi--not simply the abdominals and rhomboids normally associated with this exercise.

This helps ensure that one muscle is not working harder than it should while another muscle is failing to carry its share of the load.
