Perfect for you if...

  • You're an athlete or serious fitness enthusiast frustrated that generic training advice doesn't match your results or how you feel throughout your cycle.
  • You want to understand how your hormones affect everything from muscle gain to recovery, and you're willing to change your approach based on actual physiology.
  • You're navigating pregnancy, perimenopause, or menopause and need practical guidance on training and nutrition that accounts for these life phases.

Maybe not for you if...

  • You're looking for a quick-fix diet or workout plan rather than a deeper understanding of how your body works.
  • You're uncomfortable discussing menstrual cycles, hormones, or reproductive health in detail.
  • You prefer high-level motivation over the specific science, research, and technical detail that fills this book.

About this book

Women are not small men. Stop eating and training like one. In ROAR, exercise physiologist and nutrition scientist Stacy T. Sims, PhD, teaches how to adapt nutrition, hydration, and training to work with unique female physiology rather than against it. By understanding your physiology, you can maximize performance on and off the sports field. The book covers building fitness foundations with guidance on body composition, lean muscle gain, and nutrition. Because female physiology changes over time, full chapters address pregnancy and menopause. This revised edition includes new research and updates on women's sports, covering: an action plan for peak performance across menstrual cycle phases; the impact of hormonal contraception on training; protein needs across your lifespan; sleep as a recovery tool and managing circadian disruptions; saunas, cold plunges, and other recovery techniques for female physiology; and biohacking approaches for active women. Whether your activity is Olympic lifting, general fitness, endurance, or field sports, this book provides personal insight and knowledge to support your health and fitness goals.
