I was shocked.
Abstract only, you can read the rest.
Human mate choice is influenced by limb proportions.
So far, so obvious.
Previous work has focused on leg-to-body ratio (LBR) as a determinant of male attractiveness and found a preference for limbs that are close to, or slightly above, the average. We investigated the influence of two other key aspects of limb morphology: arm-to-body ratio (ABR) and intra-limb ratio (IR). In three studies of heterosexual women from the USA, we tested the attractiveness of male physiques that varied in LBR, ABR and IR, using figures that ranged from −3 to +3 standard deviations from the population mean.
You win a cookie.
We replicated previous work by finding that the optimally attractive LBR is approximately 0.5 standard deviations above the baseline.
Health advantage (fitness) over mean.
We also found a weak effect of IR, with evidence of a weak preference for the baseline proportions.
All the cookies.
You didn’t fake anything.
In contrast, there was no effect of ABR on attractiveness,

Bicep curls won’t save an ugly mug, sorry.
And if they did, they’d still complain and call women shallow.
Like evolution is something superficial?
and no interactions between the effects of LBR, ABR and IR.
See, this is how you science.
THIS IS HOW YOU SCIENCE.
Our results indicate that ABR is not an important determinant of human mate choice for this population,

and that IR may exert some influence but that this is much smaller than the effects of LBR. We discuss possible reasons for these results, including the limited variability in upper limb proportions and the potentially weak fitness-signal provided by this aspect of morphology.
Gym also means you throw off ratios with circumference and other noise. Optical illusions tend to operate on this principle. Women adapt out of being fooled.
A peacock can’t exercise into better plumage, LBR is the human genetic equivalent.
This is a solid finding, LBR is the male version of female WHR.
It’s nice to see someone take a male study seriously. We need more data so men aren’t pointlessly chasing a marketing dream of abs and pecs. Homoerotic fantasies pushed by gay designers won’t attract women.
I want to see a study in preference for the artificial look of gym bodies (both sexes) against likelihood of personality disorders.
