The obesity crisis is a discourse that has established common-sense understandings that all young people are less active and fit than previous generations. Unquestioning acceptance of the links between fitness and obesity in turn leads to unproblematic fitness testing of young people. This research investigated the personal and embodied experiences of fitness testing amongst university students who will in the future teach health and physical education. Foucault's ideas around technologies of self offer possibilities for understanding fitness tests as a means to discipline classify and regulate young bodies. The work is also informed by notions of "embodiment" to assist in understanding the way individuals experience their bodies in and through fitness testing. The data gathered and analysed contributes to a growing body of evidence that suggests that fitness testing is not a neutral practice and there is need for educators to problematise taken for granted assumptions and practices around fitness testing.
