This study examines the gender politics in physical education curriculum that influence students to disengage from physical education and sport. For the analysis, we selected five students among survey respondents who identified as cis-gendered heterosexual women and conducted semi-structured interviews. The grounded theory approach (GTA) was utilized and MAXQDA Analytics Pro2018 was used to assist the analysis.The analysis generated nine primary categories, for example; "visibility", "physical education curriculum", and "characteristics of exercise". It also generated forty-nine sub-categories. The relationships among categories indicate a "negative spiral" in which "poor exercise experience", "low physical skill and strength", "negative experience" and "negative emotional reaction" formed a chain relationship. Central to physical education curriculum is the focus on modern sports that has been developed as a tool to educate men. Such physical education is characterized by athleticism, record setting, hierarchy, and winning, as well as physical performance. The space of physical education is saturated with value orientation based on high performance. In such space, participants have had negative experiences in which their poor skills and physical weakness were exposed to their peers. They also expressed discomfort that physical education leaves little space for values outside of physical performance to be recognized.
