Bigger isn't always better: an exploration of social perception bias against high levels of muscularity in women.

Bodybuilding is often considered more appropriate for men than for women. Previous research has shown that knowledge of a target's involvement in bodybuilding influences interpersonal judgments. The present study examined whether this is also the case for women with competitive-type bodybuilder physiques. Participants (N = 263) were shown photographs of women who competed professionally in different categories of bodybuilding (i.e., bikini, figure, and bodybuilding/physique). Participants were then asked to make a series of judgments on the basis of the photos alone. It was found that the degree of muscularity of the targets shaped participants' estimates of perceived outcomes and of the targets' traits in non-bodybuilding domains (e.g., expected positive life outcomes, gender role traits, and sexual orientation). Both men and women apparently considered moderate to high levels of muscularity in women targets as violations of gender norms.
