The Sports Bag is a core educational and practical toolkit developed within the SISTERS project to support trainers and facilitators in delivering training activities both for sports coaches and athletes. The Sports Bag supports learning by combining theoretical grounding, non-formal education methods, experiential activities, and guided reflection, enabling participants to critically engage with issues of gender inequality, LGBTQIA+ exclusion, discrimination, and gender-based violence in sport. The toolkit promotes gender- and LGBTQIA+-inclusive approaches by addressing both structural and everyday dimensions of sports environments. It supports participants in recognising how norms, policies, leadership practices, team cultures, and communication styles can reproduce exclusion, while also providing concrete tools to foster safe, respectful, and inclusive sports spaces. The Sports Bag bridges the gap between theory and practice, supporting participants in applying learning outcomes directly to their professional roles or sporting contexts.
