Fitness Against Fascism

Fitness Against Fascism (FAF) is a workout event series and fundraiser curated by and benefiting SoapBox Productions and Organizing. It pairs an anti-oppressive, liberatory-minded high-intensity interval training (HIIT) workout and trauma-informed yoga session with a community conversation about real holistic health, the impact of structural -isms in our everyday lives, and how to challenge them all while getting a well-rounded workout! FAF decolonizes the notion that fitness is apolitical as the event curates a space for sweat and solidarity in order to breakdown systems and institutions of oppression that affect every industry, including (and especially) the allied healthcare continuum. We can talk about nutrition, fitness, and self care all day but if we are not centering holistic environmental, social, political, cultural, and economic factors into our analysis, we are not only doing ourselves a disservice but harming others. With a radical social justice mandate, SoapBox’s unapologetic event series resists, reimagines, and rebuilds a more equitable world in fitness and beyond in an intentional and participatory manner. Let’s do the work, in every sense.
