Social dominance orientation predicts drive for muscularity among British men

• Drive for muscularity is associated with indices of power, status, and dominance.
• Drive for muscularity is predicted by support for group-based dominance hierarchies.
• Drive for muscularity is associated with ideologies that favour social dominance.

The present study tested the hypothesis that men's drive for muscularity would be associated with their valuation of domination, power, status, and aggression over others. A community sample of 359 men from London, UK, completed measures of drive for muscularity, social dominance orientation, right-wing authoritarianism, trait aggression, and need for power, as well as their demographic details. Bivariate correlations showed that greater drive for muscularity was significantly correlated with most of the measures and their subscales. However, in a multiple regression analysis, the only significant predictor of drive for muscularity was support for group-based dominance hierarchies (Adj. R2 = .17). These results suggest that men's drive for muscularity is associated with a socio-political ideology that favours social dominance.
