The part of our abdomen is called the anterior abdominal muscle, which is wide at the top and narrow at the bottom. It is divided into several parts by transverse tendons, maybe one or eight, but this is not obvious, especially when you don't practice abdominal muscles, your front abdominal muscles are just a piece of meat. If you practice, he will appear 6 or 8 pieces, which are all determined by your genes. You can't change it by practicing hard.
So in fact, we can see that the principle of practicing abdominal muscles is very simple. As long as your body fat is low enough, 13%, and there is not enough meat in your abdomen, your abdominal muscles will show up. As for whether you have abdominal muscles, it depends on whether you can keep exercising. After all, heredity and thinness alone are not enough. In fact, there is also a saying that the biological evolution of people with eight abdominal muscles is insufficient and incomplete. Just like stick insects, a certain part of the body is missing, but the missing part does not affect its life and all actions, so it is not particularly important.
Just like we have wisdom teeth, it has no effect on our life and intelligence. If it is dispensable, we don't have to care too much about its existence. If you want to know if you are 6 or 8, you can try to practice your abdominal muscles. Or if you are thin enough, just breathe in. But people with ABS are handsome. You can try.
