Ripped Dad: Fit After 45 is the book that laid the foundation for ScienceBod.
Ripped Dad: Fit After 45 is the book that laid the foundation for ScienceBod. Seven years ago, I wrote it to help busy adults over 40 rebuild their strength, energy, and confidence using science—not hype. It became the starting point for thousands of people who were tired of confusing advice and wanted a clear, evidence-based roadmap. Since then, it has helped men and women finally get unstuck and create real, lasting results.

“This book lit a fire under me. I’m 47 with a crazy schedule — and I finally have a plan I can stick to.”
