Portrait of a man with brown, slightly tousled hair, light-colored eyes, and a beard, wearing a white lab coat over a dark blue shirt, against a gray background.

About the book

Dr. Peter S. Murano is a nutrition scientist, certified personal strength trainer, and educator with a deep passion for helping adults age with intention, purpose, and strength. Drawing from decades of academic work, personal observation and practice, he developed The AMPK–mTOR Method™ - a structured framework that simplifies the science of aging into a practical, weekly rhythm anyone can follow. His Method connects biology and physiology with real-world application, empowering readers to take control of their metabolic health, strength, and longevity - especially in life’s most defining decade. 

The author

Learn about the method

  • Aging accelerates when the body loses the balance between cellular repair and growth.
This book teaches you how to restore that balance by aligning your weekly routine with your biology’s natural rhythms.
    Inside, you’ll discover:

    • Why AMPK and mTOR act as master switches of aging

    • How to alternate “repair days” with “growth days”

    • Why this rhythm supports both lifespan and strengthspan

    • A weekly plan you can start immediately

    • The science behind metabolic flexibility, muscle preservation, and functional power

    Age deliberately, not passively.

  • Most advice focuses on one thing: either fasting, lifting, diet, supplements.
But aging isn’t a single-variable problem — it’s a pattern. This book’s unique contribution is showing you how to coordinate the pieces. If you’ve ever wished for a roadmap that makes sense… this is it.

  • This book is for:

    • Anyone entering midlife or beyond

    • People who want to stay strong, mobile, and independent

    • Readers who want a science-informed, actionable strategy

    • Anyone overwhelmed by conflicting advice
