This manifesto reimagines social justice in physical cultural studies by renaming, broadening, and building new characterizations of the body, dis/ability, mental health, exercise, social oppression, and sport. We problematize embedded ‘myths’ in exercise and sports studies scholarship for purposes of informing praxis-based research, and emancipatory practical agendas. These ‘myths’ include the embodied tragedy myth, the myth of bodily control, the sport for peace/development myth, the exercise is medicine myth, the healthism and exercise myth, the compulsory ablemindedness and exercise myth, and the exercise is cost-effective myth. Using intersecting and diverging theories, we propose new ways of knowing these taken for granted notions to springboard a new, socially just, emancipatory approach to research and practice.
