The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation.

From Olympic training centers to black-market laboratories, from Silicon Valley to South Africa, Tim Ferriss, the #1 New York Times bestselling author of The 4-Hour Workweek, fixated on one life-changing question:

For all things physical, what are the tiniest changes that produce the biggest results?

Thousands of tests later, this book contains the answers for both men and women. From the gym to the bedroom, it’s all here, and it all works.

• How to prevent fat gain while bingeing (X-mas, holidays, weekends)
• How to increase fat-loss 300% with a few bags of ice

And that's just the tip of the iceberg. There are more than 50 topics covered, all with real-world experiments, many including more than 200 test subjects.

You don't need better genetics or more discipline. You need immediate results that compel you to continue.

That’s exactly what The 4-Hour Body delivers.

From Tim Ferriss:

“For the last two years, I’ve interviewed more than 200 world-class performers for my podcast, The Tim Ferriss Show. The guests range from super celebs (Jamie Foxx, Arnold Schwarzenegger, etc.) and athletes (icons of powerlifting, gymnastics, surfing, etc.) to legendary Special Operations commanders and black-market biochemists. For most of my guests, it’s the first time they’ve agreed to a two-to-three-hour interview. This unusual depth has helped make The Tim Ferriss Show the first business/interview podcast to pass 100 million downloads.

“This book contains the distilled tools, tactics, and ‘inside baseball’ you won’t find anywhere else. It also includes new tips from past guests, and life lessons from new ‘guests’ you haven’t met.

“What makes the show different is a relentless focus on actionable details. This is reflected in the questions. For example: What do these people do in the first sixty minutes of each morning? What do their workout routines look like, and why? What books have they gifted most to other people? What are the biggest wastes of time for novices in their field? What supplements do they take on a daily basis?

“I don’t view myself as an interviewer. I view myself as an experimenter. If I can’t test something and replicate results in the messy reality of everyday life, I’m not interested.

“Everything within these pages has been vetted, explored, and applied to my own life in some fashion. I’ve used dozens of the tactics and philosophies in high-stakes negotiations, high-risk environments, or large business dealings. The lessons have made me millions of dollars and saved me years of wasted effort and frustration.

“I created this book, my ultimate notebook of high-leverage tools, for myself. It’s changed my life, and I hope the same for you.”
