A comprehensive, physiology-based guide to peak performance for active women approaching or experiencing menopause-from the author of Roar, renowned exercise and nutrition scientist Dr. Stacy Sims

For active women, menopause hits hard. Overnight, your body doesn't feel like the one you know and love anymore-you're battling new symptoms, might be gaining weight, losing endurance and strength, and taking longer to bounce back from workouts that used to be easy. The things that have always kept you fit and healthy just seem to stop working the way they used to.

But menopause doesn't have to be the end of you kicking ass at the gym, on the trail, in the saddle, or wherever you work out. Once you understand your physiology, you can work with it-not against it-to optimize your performance. That's where Stacy Sims, PhD comes in. In Next Level, you'll learn the underlying causes of menopause: the hormonal changes that are causing all the symptoms you're feeling, and their impact on your wellness and performance. Then, what you really came for-what to do about it. Inside you'll find science-backed advice about training, nutrition, sleep and recovery and supplements, as well as sample exercise routines, meal plans, macronutrient planning charts, and case studies from real women Stacy has coached through the transition. It's the ultimate guide to navigating the Next Level.
