Muscle fat gap, because overweight, go to the gym to lose weight. So before going to the gym to lose weight, muscles are basically hidden in fat. Muscle accounts for a small proportion of body weight, but fat accounts for a large proportion (fat density is small, the same body weight can be different).

However, because of fitness, the weight once again reached 100 kg, because the proportion of muscle increased and the proportion of fat (body fat rate) decreased. Therefore, we can intuitively see that the vest line of the body is basically invisible when the weight exceeds 100 kg before going to the gym, but the muscles seen when the weight exceeds 100 kg after going to the gym are obvious, even with obvious ribs, but the sebum is very thin.

Extended data

(1) before going to the gym, because there is too much body fat, the place where the body should not have meat is full of meat, and there is a big belly, a lot of fat on the thighs, round arms and obvious double chins. However, after the period of slimming and muscle building, the body weight has reached 100kg, and the body belongs to the place where there should be meat, but there is meat on the stomach, neck, arms and thighs. Therefore, the body will be slimmer after the same weight fitness.

② Moreover, due to the substantial reduction of body fat rate. The skin of the body is tighter, and the "meat" on the face will appear tighter and will not be as loose as before. Moreover, due to the function of muscles, the appearance of the fleshy chest and buttocks will be better, the chest will be more straight and the buttocks will be more upturned.

Moreover, because of the huge difference between fat and muscle volume with the same weight (the volume of 1kg fat is roughly equal to the volume of 1.4kg muscle), even if the weight is the same before and after fitness, the body shape after fitness will appear much smaller (much thinner) than before. Therefore, don't worry about long muscles, even if they are low in body fat, they will still be thinner and better looking than before.
