It is normal for a person's chest to droop naturally. You are fat, your chest is fat, that is, you have practiced the beauty of keys. If you do not exercise for a long time, your breasts will sag. After practicing chest muscles for two years, the whole chest contour has widened, which is different from the fat man's big breasts. The naked eye can tell which is a naturally growing fat breast and which is an exercised chest muscle.

One: you can exercise all the year round to keep your chest muscles tall and straight (people with spare money and leisure time are suitable for bodybuilding, and ordinary people can also exercise), and two: let nature take its course.
