This comprehensive guide offers practical and evidence-informed strategies for supporting women's health across the lifespan. Each life stage is explored in a dedicated chapter, including adolescence, mid-adulthood, perimenopause, menopause and older adulthood, addressing the hormonal, emotional and physical changes that occur at each life stage. Structured around six core pillars of health - physical activity, restorative sleep, nutrition, stress management, avoidance of risk behaviours, and social connection - the book also includes case studies throughout, alongside personalised health plans and practical guidance to support effective client care. By addressing areas of women's health that are often under-recognised or under-treated, health and fitness professionals will be equipped with the knowledge and tools to support informed, sustainable lifestyle change. The book also empowers women who wish to take greater ownership of their health and wellbeing.
