What makes a man's body attractive? In many mammalian species, females evolved to prefer the strongest males. According to research from Griffith University, the same is true of humans.
Dr Aaron Sell from the School of Criminology and Criminal Justice said 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 said.
"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."
In the study, the researchers tested how important physical strength is to men's bodily attractiveness by showing women pictures of men's bodies and asking they how attractive they were.
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. The effect of strength was so large that none of the 150 women in the study preferred weak men. Furthermore, 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 percent of the variance in attractiveness,'' Dr Sell said.
"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."
Dr Sell said while the women in their study preferred the strongest bodies, there was a sizeable dataset across many cultures that showed women did not always prefer the strongest looking faces.
The study was published in Proceedings of the Royal Society B today.

You need to make a choice: either pay a premium for tailored clothing or spend more time on the couch scarfing potato chips.

5 / 5 (3) Dec 13, 2017-To be truly unbiased, photos of weak rich men with their bank statements must be included.
I think a woman's priorities change. As tropical animals our first priority shortly after puberty is to reproduce at any cost. This is quickly replaced by the desire to discern quality by compelling suitors to compete physically. But as women get older their desire is to have a partner who can provide economic security for the children she has already born.
Obviously these 3 different mates need not be the same person. And chances are, one man cannot fulfill these 3 different roles.
That's why a woman's natural propensity is to trade up, which is an obvious detriment to tribal cohesion and stability; as is a man's natural propensity to impregnate as many women as possible.
Understanding this quickly leads one to appreciate the value of domestication to society.

Enactivsm may imply reciprocity.
Seriously though ladies, quads= more testosterone= more brain. Whether they have the balls to squat or the voraciousness for running to spur neurogenisis.

1.8 / 5 (4) Dec 13, 2017When you hold all other factors constant then selection will be based only on those factors or properties that vary. If two cars in the showroom are identical but one of them has a slightly faster automatic antenna extension and retraction then that is the one you will choose even though you probably never even considered this property in any of the cars you previously purchased.
I call it the 'Antenna effect', when only one property varies it will appear to have an importance far greater than it actually has, which could, in real conditions, be as low as zero (a routinely ignored property).

3.3 / 5 (7) Dec 14, 2017Oh gee, don't you understand statistics and people?
Studies like these are about averages. Every human trait is part of a bell curve shaped distribution.
Finding counterexamples on both sides of the average is easy, they are guaranteed to exist.
They prove nothing.

Like I say the perception of fitness is different for different age groups.

not rated yet Jan 17, 2018Of course if all other parameters are controlled and one only sees the physical then physical fitness, youth, apparent health and robust (but not excessive) musculature is going to be preferred. But how much influence does the physical have on attractiveness?
There have been studies on this very issue and a strong correlation with the menstrual cycle has been established with the physical having a greater influence when the female is close to ovulation. Another known studied variable is prospective sexual vs marriage partners.
It is also notable that gay men place a greater emphasis on attractive male bodies than heterosexual women do, yet another dimension entirely ignored by the study...
