After an entire lifetime devoted to the study and practice of exercising, Eric A. Glickstein has documented the reasons why it is impossible to personalize training without an understanding of the influences of intramuscular forces that represent our efforts against the effects of external forces that resist them. Consequently, "The SARCOMATRIX of Exercise" is an expose on the naive standards of typical personal training education that repudiates the relevance of forces, a thesis on the contraction of intramuscular forces that grant joint mobility, a chronicle of all the steps in the process of preparation and personalization for any kind of performance goal, and a tribute to Tom Purvis, founder of Resistance Training Specialists(r) and progenitor of the Exercise Mechanics(r) upon which the book is based.
