You can go to the gym for months, but never see progress from classes, be disappointed in training and abandon them. However, wait! Let's first figure out, do you really train and eat correctly? What exactly prevents you from reaching the desired result? Training is a process that is built according to certain, fairly simple rules. These rules are dictated by our anatomy and physiology, hormones, calorie content of food and other factors. All this together determines what effect the classes will have. The book brings together cutting-edge fitness knowledge and addresses key rules for an effective workout. You'll learn how to eat so you don't gain weight, how the calorie deficit works and why eating separately is a myth.
