ROAR, Revised Edition

About ROAR, Revised Edition

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 your unique female physiology, rather than against it.

By understanding your physiology, you’ll know how best to adapt your lifestyle and build routines to maximize your performance, on and off the sports field. You’ll discover expert guidance on building a rock-solid foundation for fitness and everyday life with tips for determining your high-performance body composition, gaining lean muscle, and nailing your nutrition. Because a women’s physiology changes over time, you’ll also find full chapters devoted to pregnancy and menopause.

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, including:

• An updated action plan for peak performance across all phases of your menstrual cycle, as there is never a bad day to perform at your best
• A fresh understanding about the impact of hormonal contraception on training
• A look into why you need more protein than the average woman and how these needs change across your lifespan
• The reasons why sleep is your most powerful recovery tool and how to manage disruptions to your internal clock
• A deep dive into saunas, cold plunges, and other training and recovery techniques as they apply to female physiology
• Insights into biohacking and what works (and doesn’t) for active women

About ROAR, Revised Edition

“Dr. Sims realizes that female athletes are different than male athletes and you can’t set your race schedule around your monthly cycle. ROAR will help every athlete understand what is happening to her body and what the best nutritional strategy is to perform at her very best.”—Evie Stevens, Olympian, professional road cyclist, and current women’s UCI Hour record holder

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

Because most nutrition products and training plans are designed for men, it’s no wonder that so many female athletes struggle to reach their full potential. ROAR is a comprehensive, physiology-based nutrition and training guide specifically designed for active women. This book teaches you everything you need to know to adapt your nutrition, hydration, and training to your unique physiology so you can work with, rather than against, your female physiology. Exercise physiologist and nutrition scientist Stacy T. Sims, PhD, shows you how to be your own biohacker to achieve optimum athletic performance.

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 as you build lean muscle where you need it most, strengthen bone, and boost power and endurance. Because women’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.
