Why do women love muscular men while guys don't have much liking for pumped-up girls?

Beauty standards are, of course, yes. However, the same standards of beauty have undergone numerous mutations over time, not to mention the geographical location of the peoples where these or those standards take place. But we are now talking about perception in general.

In my opinion, the matter here lies somewhat deeper than the usual visual appeal. A person's appearance in one way or another gives information about his internal structure. The sight of a woman with pumped muscles in one way or another makes it clear about her tendency to dominate, the average man does not like, does not tolerate and does not agree to be in a subordinate position, dependent on a woman - this happened in the course of social evolution. Even if you imagine that a woman bodybuilder turns out to be the most delicate and feminine creature, she sends a completely different visual signal.

A man, on the other hand, is normally much more physically developed than a woman. And here again, at a subconscious level, worked out attitudes for centuries are turned on - which means that the most physically developed specimen will be able to more successfully perform the tasks assigned to it in society. Women instinctively perceive and interpret this based on their needs. So, in my opinion, the point here is not entirely and not only in external beauty. Beauty is more of an effect than a cause.

Therefore, as mentioned earlier, this perception is based on the instinctive nature of a person, which has not gone anywhere for many centuries, but on the contrary, is even actively encouraged.

Because they look like men. And in the head of such, judging by their physique, and, accordingly, and the way of thinking, there is not much intelligence. But this is their right. The right to live alone with dumbbells.

Because a pumped woman does not meet traditional standards of femininity and attractiveness. Typically, the "fair sex" feel sympathy and sexual attraction to inflated men, because this is considered the standard of beauty and in the same way do not pay attention to those who do not have outstanding muscle mass. Men act in the same way - slim means feminine; pumped - masculine.
Again "in taste and color." Someone's ideals of beauty contradict traditional ones.

It is obvious that a number of standards of attractiveness, no matter how feminists and others like them denied, were laid down over hundreds of thousands of years of human evolution and subconsciously have an impact on today. Be that as it may, most women in one way or another perceive a man as a getter - and it is important for him to be strong, aggressive, fast. Muscle relief is what you need. In the man's brain, on the contrary, there is an awareness of the woman as the keeper of the hearth and potential mother - and the mother does not have to be muscular. In addition, such embossed young ladies sometimes very much resemble men. More on the topic in the movie "Why Men Never Listen and Women Can't Park"

Because there is a stereotype in society that men are strong and women are weak. The difference in average physical strength, which most likely has biological reasons, is perceived by many not as relative, but as absolute, and is unreasonably transferred to strength of character. As a result, physical activity is more encouraged in men than in women, and socially determined is added to the biological difference in average physical strength. Men's sports records are about 20% higher in performance than women, and the physical strength of the average man is about 1.5 times that of the average woman. It can be assumed that the additional 30% of the difference to the 20% biological difference is introduced by social factors that have little effect on athletes. Likewise, the fact that men are more likely to encourage self-confidence can be manifested in the behavior of the average man and the average woman. The notions that a man should be strong and a woman should be weak carry over to the question of the appearance of a pumped-up body. But not all people of both genders follow these ideas.
