The groundbreaking book that revolutionized exercise nutrition and performance for female athletes, now freshly updated

Women are not small men. Stop eating and training like one.

In ROAR, exercise physiologist and nutrition scientist Stacy T. Sims, PhD, teaches you everything you need to know to adapt your nutrition, hydration, and training to work with (rather than against) your unique female physiology.

Complete with goal-specific meal plans and nutrient-packed recipes to optimize body composition, ROAR contains personalized nutrition advice for all stages of training and recovery. Customizable meal plans and strengthening exercises come together in a comprehensive plan to build a rock-solid fitness foundation through gaining lean muscle where you need it most, strengthening your bones, and boosting your power and endurance.

This revised edition includes a wealth of new research developments, expanded recommendations based on those findings, and updates to reflect the changing landscape of women's sports. Because a woman’s physiology changes over time, entire chapters are devoted to staying strong and active through pregnancy and menopause.

No matter what your sport is—running, cycling, field sports, triathlons—this book will empower you with the nutrition and fitness knowledge you need to be in the healthiest, fittest, strongest shape of your life.
