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
No matter what your activity is—Olympic lifting, general fitness, endurance, or field sports—this book will empower you with the personal insight and knowledge you need to be in the healthiest, fittest, strongest shape of your life.

Hotel Grand Set of 2 pillows
Size: King
Excellent quality and comfort. The pillows are soft but with the perfect support, ideal for any sleeping position. They feel fresh thanks to the cotton cover and keep their shape very well. Without a doubt, a great purchase for a hotel-like break at home.

Highly recommend
Size: King
These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them.
They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase

Time will tell
Size: King
I won’t actually use these for a few days when my mattress arrives. Unboxed this morning and they are not as plump and full as I expected but they’re laying out to expand. Overall first impression is they felt comfortable and I could adjust them with my hands. They seem well made and durable. Cant say anything yet about firmness or shape retention since I’ve not used them. They feel like they will be soft. So time will tell but so far I’m loving what I see.
