The chapters in this edited collection examine how the culture of masculinity intersects with issues of health, homophobia, and the suppression and silencing of anxieties about body image among men and boys. Examining the bodily dividends and trade-offs associated with male participation in physical activity is central to understanding how educators in particular might better engage all boys in healthy life practices, not only those privileged by muscularity and physicality. Contributions explore evidence of intimidation and body fears that is largely unheard and unexplored in locker rooms and classrooms. Introducing critical perspectives emerging from current evidence-based international research to shed light on curricular and policy initiatives aimed at producing healthy children, this book will powerfully inform and provoke discussion.
