The aim of this study was to qualitatively examine weight stigma in individuals who exercise frequently. In total, six focus groups, comprising 30 participants aged 18-25 years, were conducted using convenience sampling. All participants were frequent exercisers. Five themes emerged in the data with participants discussing bullying, the consequences of obesity, causes of obesity, lack of willpower and interventions to reduce obesity. This study is the first qualitative examination of weight stigmatisation in frequent exercisers, where the beliefs reported by focus group participants suggest that frequent exercisers stigmatise, discriminate and dehumanise obese people. Future research to examine the impact of weight stigma on exercise motivation and behaviour of obese people appears warranted.
