#1 NEW YORK TIMES BESTSELLER • The game-changing author of Tribe of Mentors teaches you how to reach your peak physical potential with minimum effort.
“A practical crash course in how to reinvent yourself.”—Kevin Kelly, Wired

Is it possible to reach your genetic potential in 6 months? Sleep 2 hours per day and perform better than on 8 hours? Lose more fat than a marathoner by bingeing? Indeed, and much more. 

The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body using data science. 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 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. It’s the wisdom Tim used to gain 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time. From the gym to the bedroom, it’s all here, and it all works. 

You will learn (in less than 30 minutes each):

• How to lose those last 5-10 pounds (or 100+ pounds) with odd combinations of food and safe chemical cocktails
• How to prevent fat gain while bingeing over the weekend or the holidays
• How to sleep 2 hours per day and feel fully rested 
• How to produce 15-minute female orgasms 
• How to triple testosterone and double sperm count
• How to go from running 5 kilometers to 50 kilometers in 12 weeks 
• How to reverse “permanent” injuries  
• How to pay for a beach vacation with one hospital visit
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 exercise. You need immediate results that compel you to continue.

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


  • This book is not a straightforward read

    By Back to reading again
    Ugh! I just got this book & I'm having a hard time making myself read it! I feel like they tried to combine to much info in it. I'd prefer to read this is what you need to do... & then have a section for the research & results but it's all mixed together so you have to read it. Which makes it hard to go back & find information that you thought was helpful & want to remember

    By Brandenn O.G.
    A fascinating look into the world of producing extraordinary physical ersults in small amounts of time. Covering a wide variety of topics, this book is worth its weight in gold. I particularly enjoyed the pieces on testosterone, fat loss, muscle gain, and sleep.

    Great book, easy to follow.
  • Put it to the test!

    By Dillydal12
    I love reading bad reviews, because more often than not the people who wrote them didn't apply the information in their lives. If they tried, they failed to do so correctly. I have put these principals to practice, and Tim hits it all on the nose. The book is so informative that I have had to read through it multiple times. Tim is also humble about this book acknowledging that health and science are always evolving, and that the ideas and practices presented in this book may be obsolete soon; stating that we as readers should stay up to date on new research and health concepts. This book changed my life, and my ideas about health, fitness, and habits. A good book to read in accompaniment with The Four Hour Body is The Power of Habit, it helps you know how to replace your bad habits with Four Hour habits. They both blew my mind, and helped me greatly advance in my life. Thank you Tim!
