The boxing gym is widely regarded as a bastion of masculinity; historically, the exclusive domain of men. Although women remain a minority in the boxing gym, the past two decades have seen a growth in numbers. A small but significant number of women are increasingly drawn to boxing gyms for leisure, often as alternatives to mainstream fitness spaces, which many experience as exclusionary and uncomfortable. Drawing on ethnographic research conducted in a traditional boxing gym in Glasgow, this paper centres the lived experiences of women boxing for leisure rather than elite competition, and examines how they perceive, negotiate, and resist gendered constraints through their engagement withthe gym. The analysis adopts a feminist theoretical orientation, mobilising the concept of affective assemblages to account for the collective and embodied dimension of experience, yielding deeper insight into the dynamic contexts of leisure and the spatial power structures that facilitate or hinder women’s inclusion (Pavlidis 2018). This paper argues that while the boxing gym remains a masculine space, its salience is perceived, embodied, and negotiated in different ways and to varying degrees by the three groups of women identified at the gym: the women boxers, the keep fitters, and the women-only boxers. On the one hand, the gym is experienced as an enabling and empowering space, where women can embody aspects of masculinity and challenge gendered expectations. On the other hand, it’s also a constraining space where some women feel more entitled to claim space than others; confined and constrained both by their gender and the gender of the gym, they remain out of place and on the periphery. Overall, this paper advances spatial feminist analysis by foregrounding women’s leisure boxing. It argues that traditionally masculine leisure spaces are not always exclusionary to women, thereby complicating dominant narratives of empowerment, inclusion, and exclusion within sporting spaces.
