Beyond the Metrics examines how fitness technology subtly affects self-image, social anxiety, and mental well-being through wearables, performance monitoring, and digital affirmation. It uniquely combines academic insights with their practical experiences in competitive sports, user experience, and psychosocial research. It critically examines how fitness technology, while intended to be empowering, can paradoxically lead to self-objectification, social comparison, and performance anxiety. The authors explore the mental health effects of focusing on numbers related to the body, including body dysmorphia in bodybuilding and anxiety from online fitness tracking and social media. This timely book uses sports science, psychology, user experience (UX), and gender studies to explore the risks and potential solutions. Perfect for researchers, mental health professionals, athletes, and tech designers.
