Although trans studies borrow concepts from men’s studies to reflect on trans masculi­nities, men’s studies show little interest in trans issues. This exclusion of trans people illustrates the larger problem of their exclusion from health research. Despite a growing literature on masculinity, health and bodybuilding, trans men’s relationships to bo­dybuilding and its role in the construction of their masculinity remain unexplored. While many studies on masculinity and bodybuilding rightly show that this practice serves hegemonic masculinity, I argue that this interpretation does not use an intersectional analysis that incorporates gender identity (transgender/cisgender) and exposes the heuristic value of trans theories for the sociologies of gender, health and sport in rethinking links between masculinity and bodybuilding.
