(Re)claiming subversive spaces on TikTok: the complexities of body activisms within physical activity cultures

Feminist organising in digital spaces, such as social media, has the potential for activism, resistance, and visibility; yet these spaces continue to be dominated by narrow body representations and shaped by unequal power dynamics. We propose that bodies of difference may find vibrant and difference-affirming homes within their digital communities via innovative algorithm-based social media spheres, such as TikTok. Using a creative methodological mashup that we call a 'collaborative digital autoethnography', we explored our experiences of difference-affirming hashtags (e.g. #CurvyGym, #DisabledFitness, #QueerFitness) and creators who shared explicitly inclusive and/or subversive content (e.g. #ThickTocker). Using reflexive thematic analysis and thinking with/through Safiya Noble's work on algorithms of oppression, we developed four themes: #TheFringe, #(Re)claimingFlesh, #CircleOfSurveillance, and #TheWrongSideOfTikTok. In #TheFringe, we found normatively embodied creators who used TikTok as a space to question normative fitness trends – content that helped build our difference-affirming algorithmic space. In #(Re)claimingFlesh, fat-positive creators used TikTok to unapologetically reveal or grab body fat/flesh, and TikTokkers re-storied their body-related journeys by flipping the script of harmful body surveillance (i.e. #CircleOfSurveillance). Lastly, some creators shared grievances about the (oppressive) algorithms of TikTok that banished them to #TheWrongSideOfTikTok. We provide reflexive accounts of our own embodied differences while exploring the TikTok platform, searching for spaces that affirm our bodies while contending with algorithmic oppression. We conclude by discussing TikTok as a platform where powerful collective activism and revolution can form, yet always in contention with trolling, hate, and harmful algorithms that constrain activist movements within sport, exercise, and health contexts.
