The present study tested the hypothesis, derived from feminist perspectives on body image, that men's greater endorsement of sexist attitudes and objectification of women would be associated with their own drive for muscularity. A total of 327 British men completed scales measuring their drive for muscularity, sexist attitudes, hostility toward women, objectification of women, and key demographics. Results showed that greater drive for muscularity was significantly predicted by stronger objectification of women, hostility toward women, and sexist attitudes, once men's age and body mass index had been taken into account. These results suggest that oppressive beliefs held by men are associated with a desire for a more muscular physique. Implications for theoretical models seeking to explain drive for muscularity among men are discussed in conclusion.
