Aligned

“Aligned makes a convincing case for recovery as the foundation of performance. Dr. Holmes shows how recovery and emotional resilience improve when we work with the body’s natural circadian rhythms, rather than against them. The result is a book that feels both rigorous and genuinely useful.”—Michael J. Breus, PhD, ABSM, author of The Power of When

“In a world that rewards urgency and exhaustion, Aligned offers permission to slow down and live with intention. Holmes guides each of us to listen more deeply, to our bodies, our rhythms, and, most importantly, our values, and to live from that place of awareness. This book is, refreshingly, not about optimization or achievement, it’s about wholeness.”—David Perlmutter, MD, New York Times bestselling author of Grain Brain and Brain Defenders

“Dr. Holmes has written an incredible book that revitalizes the human body and the human spirit. I am thrilled to have her scientific expertise and decades of experience at my fingertips. A must-read for anyone looking to become the most exceptional version of themselves.”—Dr. Gabrielle Lyon, New York Times bestselling author of Forever Strong and The Forever Strong Playbook

“Dr. Holmes bridges something that is rare in the performance world—deep scientific rigor and real coaching experience in high-stakes environments. In Aligned, she shows that sustainable performance isn’t about hype or hacks, but about understanding your physiology, respecting recovery, and building daily habits that compound over time. A practical, science-backed guide for anyone serious about building resilience and sustaining full-body health over the long haul.”—Dr. Kelly Starrett, New York Times bestselling author and co-founder of The Ready State

“We often think of performance only in terms of what our physical body is capable of. The reality is, our body, mind, and spirit are an interconnected ecosystem of balance, stress, and recovery. As an elite sports surgeon, I’ve seen this ecosystem become dysfunctional when not aligned. In her brilliant book, Aligned, Dr. Kristen Holmes brings us a data-centered approach to total alignment for performance in sports, work, and relationships. Her knowledge and warmth shine through the pages, as if you are sitting across from her in marvelous conversation.”—Vonda Wright, MD, MS, orthopaedic surgeon and author of New York Times bestseller Unbreakable

“Aligned is a must-read for anyone who wants to achieve big goals in their life — by harnessing the biology of resilience, stress, and readiness. This is the roadmap for how to outperform yourself.”— William W. Li, MD New York Times bestselling author of Eat To Beat Disease and Eat To Beat Your Diet, President and Medical Director, the Angiogenesis Foundation

“Kristen Holmes has spent her life studying how humans can show up every day and compete at the highest level. Her championship resume as an athlete and coach at Princeton created an incredible foundation for her work as a scientist. Aligned offers a core truth: The highest level of excellence can only be accomplished one way, through total alignment—heart, mind, and body—so you can live out your deepest values with joy and energy.”—Jim Murphy, author of Inner Excellence

“Dr. Holmes has a unique ability to turn complex science into simple truths that change how you live and perform. At WHOOP, we’ve seen firsthand how her work helps people stop guessing and start listening to their bodies. Aligned brings that to life. She shows that real performance isn’t about pushing harder, it’s about working in sync with yourself. I have worked with Dr. Holmes everyday for the past decade and she embodies the message she preaches.” —Will Ahmed, Founder & CEO, WHOOP
