Anaerobic strength training mainly consumes sugar.
The principle of long muscles is that the worn muscles are repaired by protein, and then the muscle fibers become thicker.
Sugar and fat are like oil in a car, and muscles are like car engines.
Fat will not become muscle, they are not the same substance at all, but more muscle will consume more fat every day.
It's hard to grow muscles. The human limit is 1 6.7 139 6ˉ9kg, which is based on high-intensity strength training, adequate diet, good sleep and no psychological pressure.
