Interval training; conditioning for sports and general fitness

"..... We wrote this book for the coach, the athlete, and the person who desires to condition himself for health purposes. Elementary physiology of exercise, designing the ITP for athlete and business executive alike, as well as SELF TESTING AND EVALUATION ARE AMONG IMPORTANT TOPICS COVERED. Based on experience as well as scientific knowledge, mass calisthenics and continuous exercise routines are "older than antiquity."..... [from the book of the preface, by Edward L. Fox and Donald K.
