#1 NEW YORK TIMES BESTSELLER The game-changing author of The 4-Hour Workweek 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.
