The book is based on Mentzer's personal experiences and his innovative approach to bodybuilding. The authors argue that the traditional principles of bodybuilding - intensity, duration, and frequency - are not enough. Instead, they propose seven fundamental principles that form the matrix of bodybuilding science.
