On the one hand, there is a lot of fat, and the abdominal muscles are wrapped in fat. No matter what shape the abdominal muscles are, you can't see the vest line, so naturally lose fat first. This is the first step. First, judge whether you have a lot of fat on your stomach. The judgment method is also simple. Make a flat support in front of the mirror, and then look in front of the mirror to see how much fat there is in your stomach. Fat can't contract by itself. It is the abdominal muscles that are tightened when doing the flat plate, so it is more convenient to observe the fat. If you can clearly see the drooping abdomen, you must lose fat first. Visually, the body fat rate of the subjects is not very high, so they can be trained directly.
On the other hand, if you are a thin man, similar to the subject, you should start practicing abdominal muscles. Everyone's abdominal muscles will be different in shape and size, but the abdominal muscles of ordinary girls are still relatively small and weak. Without training, it will make him bigger. Even if you slim down and show the vest line, can you look good? For an extreme example, let's go to Baidu to search for pictures of anorexia patients and see what their stomachs are like. If there are too many pictures, I won't go to see them. What we want is beauty, not thin ribs stuck to the skin, exposed abdominal muscles, and horrible mermaid lines that are not much thicker than fingers.
The main topic is abdominal muscle training. It is recommended to fix the upper body and lift the legs or knees, so that the mermaid line will come out faster.
