Abstract
Whilst a substantial body of evidence supports the benefits of exercise for physical and mental health, the overfocus on the benefits of exercise could result in harmful behaviours in some individuals. Conceptualised as a behavioural addiction, research often dichotomises the behaviour through a medical diagnostic model. The present qualitative study explored the meaning of problematic behaviour from the exerciser's perspective. Nineteen UK-based frequent exercisers were interviewed regarding their experiences. Thematic analysis described three themes: 'relentlessly pushing the limits' of their personal best and comparing to others; 'an enabling community' which could promote problematic behaviours; and 'the complexity of the ideal body' focussing on perceptions of weight maintenance. Transcending these themes was the notion of 'rationalising choices'. The results indicate that participants felt that the benefits outweighed the costs, encouraging them to continue, even when causing harm. These findings support the notion of problematic exercise as a continuum, rather than dichotomous.
