title: Cultural expectations of muscularity in men: the evolution of playgirl centerfolds.
abstract: OBJECTIVE
  We sought to assess whether cultural ideals of the male body, as illustrated by magazine models, have changed over the past 25 years.
  
  
  METHODS
  We examined 115 male centerfold models in Playgirl magazine from 1973 to 1997. Using the models' heights and weights quoted by the magazine, together with visual estimates of body fat, we calculated the body mass index (BMI) and fat-free mass index (FFMI) of each model.
  
  
  RESULTS
  The Playgirl centerfold models became increasingly "dense" and more muscular over time, as indicated by the significant correlations between BMI, FFMI, and year of publication.
  
  
  CONCLUSIONS
  These observations, in combination with previous studies, suggest that cultural norms of the ideal male body are growing increasingly muscular.
