This article explores men's talk about physical activity, weight, health and slimming. Drawing from qualitative data from men whom medicine might label overweight or obese, it outlines various ideal typical ways of orienting to the idea that physical activity promotes "healthy" weight loss before exploring the most critical display of perspective: justifiable resistance and defiance. This gendered mode of accountability comprises numerous themes. These range from the inefficiency of physical activity in promoting weight loss to resisting imposed discipline. Theoretically and politically, these data are read as a situationally fitting and meaningful response to "symbolic violence" in a field of "masculine domination" (Bourdieu 2001) - that is, a society in which fatness is routinely discredited as feminine and feminizing filth by institutions that are publicly reinforcing and amplifying fatphobic norms or sizism.
