The chest used to be very strong and thin, but later it became very soft. You can pinch your heel and shake it back and forth, feeling that there is no fat inside, and there is a layer of skin on the surface when you pinch it. If you don't exercise for a long time, your muscles will naturally relax, and the density and quality of your muscles will decrease. Some people do not exercise for a long time, and the muscle dimension is obviously reduced; Some people don't exercise for a long time, and their muscle dimensions don't seem to change, but they become very soft. It may be that the fat on the muscle has become thicker, or the muscle density has become lower.

As long as you exercise your chest muscles as before, you will recover soon.
