Scientists have long had the view that females, at least in many mammalian species, have evolved to prefer the strongest males. According to research from Griffith University, the same is true of humans.

A study, published in the Proceedings of the Royal Society B, tested how important physical strength is to men’s bodily attractiveness.

Women were asked they how attractive they found men’s bodies as displayed in a series of pictures.

The results showed that it was possible to almost perfectly predict how attractive a man’s body is from three things: how physically strong he looks; how tall he is; and how lean he is.

Dr Aaron Sell from Griffith’s School of Criminology and Criminal Justice says cues of upper body strength make a man attractive, including having wider shoulders, being physically fit and having greater handgrip strength.

“Evolutionary psychologists have shown that women’s mate choices use many cues of men’s genetic quality and ability to invest resources in the woman and her offspring,” he says.

“Among our ancestors, one variable that predicted both a man’s genetic quality and his ability to invest was the man’s formidability.

“Therefore, modern women should still have mate choice mechanisms that respond to cues of a man’s fighting ability.

“One crucial component of a man’s ability to fight was his upper body strength.”

The effect of strength was so large that none of the 150 women in the study preferred weak men.

And looking strong was much more important for man’s attractiveness than being tall or lean.

“The rated strength of a male body accounts for a full 70% of the variance in attractiveness,” says Sell.

“The effect of height and weight on attractiveness may indicate that women are responding to cues of health or to the benefits that height and lean bodies have in protracted aggression, hunting and other aspects of fighting ability.”

Other research shows that when it comes to faces women don’t always prefer the strongest looking.

Of course, physical attractiveness isn’t the whole story.

Previous research shows that women prefer the smell of certain men over others.

And even being clean shaven or not has an impact. Researchers at the University of New South Wales reported that women said the most attractive beard length was heavy stubble.

  • Tim Ferriss has taught me that male attractiveness can be distilled down to the ratio between shoulders and waist. Shoulders can be built, fat can be lost, and all dudes can be hot.

    Tim Ferriss has also managed to cultivate a veneer of Knowing Stuff and a self-perpetuating rat pack of people who have also cultivated veneers of Knowing Stuff and all show up on each others’ podcasts as special guests. So… he’s obviously an expert and I believe him unreservedly.

    Not mine, though. If my bank balance was a person, it would have sand kicked in its face by the guy in the first photo.

  • I’m still trying to figure out how attraction works. Based purely on the qualities such as “man’s formidability” and “man’s fighting ability”, I do wonder are those still relevant in modern lifestyle? I supposed such things are important for defense/protection and being able to do physically demanding work. Other than those practical factors, why is it that looking like Captain America, Thor or similar body types are so incredibly attractive? I get that if a person is unhealthy looking, it would be a turn off.

    “The effect of strength was so large that none of the 150 women in the study preferred weak men.”
    All I can say to that is – oof. There’s no way to compete with those men.

    Also, it would be interesting to know the type of women that are part of the research/survey.
