This paper seeks to animate discussion around how social class operates with adolescent girls from low socio-economic status backgrounds to shape and inform their decisions about participation in physical activity (PA) inside and outside of school. Examining the instance of girls in a single secondary school in an Australian regional town, the paper questions the impact of class and how the girls experience the obstacles, impediments and interferences to participation in PA. These girls are portrayed as living multiple, complex and embodied subjectivities that shape and are informed by the relational geographies in which they are located, as they interact ‘with’, ‘to’ and ‘between’ the social, emotional and classed hierarchies that require them to access familial and other resources in making decisions about participation in PA.
