Not necessarily, but it still takes a long time to become a muscular man. Under the condition of very hard training and strict diet control, the amount of pure muscle that adult men can increase every month is about 0.5 ~ 1 kg, and this increase will become smaller and smaller with the passage of training and time, because our bodies are limited and it is impossible to grow indefinitely, so after the "novice welfare period", we will generally feel more powerlessness that muscle growth is too slow.
