It doesn’t matter whether you just came to a fitness club and are a newbie in the iron world, or you have already “eaten all the dogs” in training, whether you work as a fitness trainer or just go to train “for yourself”, whether you set your the goal is to build muscle mass, develop extreme strength, endurance, or just want to lose weight - this book is for you! It has a completely non-standard approach to describing the muscles, nervous system, their functions, structure and relationships. I paid special attention to the real reasons for muscle growth, which you are unlikely to read about in any sources. This book contains everything that I have understood and discovered over thirty years of training and my work as a fitness trainer and methodologist. Here we describe something that you will no longer find in any other source collected together. This book will definitely change your understanding of muscles, the human body, training and training methods! After reading it, your knowledge of “iron” sports will never be the same!
