This isn’t about looking fit. It’s about staying capable.
Nobody warned you this was coming. One day you’re fine, and the next you’re standing up from a chair, thinking, " Why is this harder? It’s not just a long week. It’s sarcopenia—the slow, quiet loss of muscle that begins in your thirties, accelerates after fifty, and usually gets noticed only after something goes wrong.
The medical system didn’t warn you. The fitness industry didn’t either. This book does.
Not Done Yet is a science-based, no-nonsense guide to building strength, muscle, and real physical health after 50. The window to change your trajectory is still wide open—and far longer than you’ve been led to believe.
In this book, you’ll learn:
What’s actually happening in your body as you age (and why it’s not “just getting older”)How resistance training rebuilds muscle at the cellular level
What and how much to eat to support strength, not decline
How to recover properly without injury
Why “normal aging” is often just sedentary aging—and how to avoid it
This isn’t about getting back to who you were at thirty. It’s about becoming stronger, healthier, and more capable than you thought possible—starting right now.
