with Doc Fizz
Strong Beyond 40 isn't just a book.It's a conversation.
I'm Dr. Curt Ficenec, D.C. — but most people call me Doc Fizz. I wrote Strong Beyond 40 to help you understand what's happening to your body as you age, and more importantly, what you can do about it. Here, we take the conversation beyond the pages of the book.
