Tested women’s ratings of physical attractiveness and sexual desirability of muscular men
Showed the participants computer-generated pictures of men.
Adapted from Frederick and Haselton, 2007, p.1180.
Hypothesized that muscular men would report having more lifetime sexual partners than non-muscular men
Participants were 99 men with a mean age of 21.26.
Participants were photographed and asked how many different partners they had ever had sexual intercourse with.
These pictures were then showed to a group of judges (3 women and 1 man), the judges were then told to code the men for muscularity and body fat, using a 9-point Likert scale
