Fat people are easier, because fat people have excess energy, which is not absolute! How are muscles tempered? First of all, exercise damages muscle cells, and the human body repairs muscle cells through repair, thus forming muscles, but this kind of exercise is limited, and strain may cause permanent damage! Therefore, you need a lot of protein. Anyone who has studied biology knows that sugar and fat can be easily converted, and it is difficult to convert fat into protein, but protein can be converted into fat. Why do fat people live a long life? When disasters happen, they exercise their muscles by taking a lot of protein, not by themselves!
