Great book that expands on the Sprint 8 protocol that Phil Campbell introduced in his book “Read, Set, Go”. After practicing this training method for the past 15 years, I heartily recommend this training approach.This is not a gimmick or fad approach. It is an approach to fitness and improvement of athletic performance. Having won some 60 medals in Track and field competitions over the past fifteen years, I attribute my health, fitness, and improvement in athletic abilities to practicing the Sprint 8 protocol. Thanks Phil for another good book to get us going. – Ed
