Why is the "muscle girl" removed from junior high school textbooks?

Girls' understanding of muscles is basically biased, and the muscles in their mouths are basically big, and they can clearly see large muscles.

In fact, such a girl has a lot of muscle and a lot of fat at the same time, and basically can't tell whether muscle or fat leads to a big body. Boys and girls don't like girls with such muscles.

However, if you know enough about muscles, you will find that a group of people are regarded as the first in the world, and their muscle ratio is much higher than that of the muscular man who is hated by girls mentioned above. This group of people is the model group, among which Victoria's secret female model is recognized as the best figure. These female models are almost thin, but they are considered as ideal female figures.

It is quite difficult for girls to grow muscles, because the content of testosterone, an important factor of muscle growth, is very low in girls. Since it is difficult for girls to grow muscles, how are those muscular girls who are rejected by girls tempered? This is related to an important mechanism. Heat is as important to muscle growth as testosterone, so some small groups of girls with special genes grow into stout arms and legs under the stimulation of high fever, which seems to be completely ignored by testosterone.

It is difficult for most girls to grow muscles because of testosterone, while a few women with high calories and long muscles must also grow muscles with fat. It is impossible to grow muscles alone.

It can be said that in the case of girls with less fat, muscles don't grow much, while the total amount of fat and muscles is not much, and muscles account for a larger proportion, which is the case for those slim girls. According to the ratio of muscle to fat, the proportion of slim girls is higher than those with big and annoying muscles.

It is difficult for girls to get bigger when they practice muscles, and they can only increase the ratio of muscle to fat. When you are slim, most people don't see that you have a lot of muscles, just think that you are slim.

For the vast majority of girls, building some muscles will only improve the hand feel and body shape, and will not become hard or huge. Muscle women should be equal to slim women, not giants. It is difficult for girls to become giants by practicing muscles.

If the muscle index of an extreme body with muscle as the main body type is set as 10, and protein is completely ignored in the diet all the year round, then the muscle index of a body with a high ratio of body fat to muscle is set as 1. Many people with muscle index 1 are worried about the disadvantage after muscle index 10, which is ridiculous.

Even assuming that the muscle index reaches 10, those models whose standard figure is Victoria's secret may have the disadvantage of being hard and you don't want to be hard. Then you should not maintain a muscle index of 1, but seek to maintain a muscle index of 6-7, which is a girl's figure. People who pursue lines more can improve their body's muscle index to 8. But when they think of 10, only girls and bodybuilders in China can do these days, so don't think about others.
