Data crunching back to age 18. Three years of organizing self-experiments around the world. Thousands of blood tests and hundreds of case studies.
My new book is finally here: The 4-Hour Body.
I could not be happier with the end product. Truly, I am ecstatic.
If you want a minimalist guide to hacking the human body, this is it.
In each chapter (more than 50 topics total), I test everything on myself so you don’t have to. In “Reversing ‘Permanent’ Injuries,” for example, I tested the moderate options like over-the-counter supplementation and Feldenkrais, but I also imported stem-cell growth factors from Israel and had them injected. That was just for starters. The end result of that chapter? 90%+ of the injuries that plagued me for decades are now gone. I’m stronger and faster than I was at age 20.
If you want to know the two safe things out of 100 that worked abnormally well, I can tell you…
The 4-Hour Body is also designed to read unlike any diet or fitness book, which it isn’t. It’s more like a Choose-Your-Own-Adventure book for the human body, full of ridiculous stories, practical philosophies, and larger-than-life characters.
Here’s the back cover description:
THINNER, BIGGER, FASTER, STRONGER… which 150 pages will you read?
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. This is not just another diet and fitness book.
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.
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 (X-mas, holidays, weekends)
– How to increase fat-loss 300% using temperature manipulation
– How Tim gained 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time
– 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 add 150+ pounds to your lifts in 6 months
– 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 discipline. You need immediate results that compel you to continue.
That’s exactly what The 4-Hour Body delivers.
Now The Real Fun Begins
Here we go:
1) The ask
2) Big media opportunities for you
3) An offer to friends in media.
I try not to ask for too much on this blog, but today I will ask a favor: if this book sounds interesting to you, please take a moment to order it today. I’ve never worked harder on something, it’s my sophomore act, and pre-orders are critically important in the publishing world.
The book is on-sale now but will ship on December 14th. Here’s why you should pre-order now:
– You will not be charged for the book(s) until they ship in December, but ordering (really like reserving) a copy now really, really helps me.
– What would make a better X-mas gift? My dad lost more than 70 pounds using two chapters. Please consider getting a few copies for your family, loved ones, or best friends. I promise that they will not be disappointed. Ordering now means you can’t forget.
– Last but not least, your help would mean the world to me. Pre-orders will largely determine how much support retailers give this book. It’s crazy, but only hardcover sales count towards the bestseller lists. If you’ve benefited from my last book or writing on this blog, I would really appreciate your help. This has been the biggest project of my life.
The 4-Hour Body is available on Amazon, BN.com, and these online retailers.
BIG MEDIA OPPORTUNITIES:
Have you lost weight, gained muscle, or otherwise changed your body as a result of blog posts I’ve written? If so, you could be featured on major TV and in big mainstream media. Please e-mail your details and (important, if you have them) pictures to jenny.rabun-at-gmail-dot-com. No professional before-and-after pics needed, but something that shows your before and after appearance, even in normal clothes, is helpful to producers.
Ladies — that means you, too! Help a brother out, and help your sisters out, by sharing your stories!
TO MEDIA, BLOGGERS, AND LIST OWNERS:
I’ve made very few media commitments thus far. Do you have a column, show, mailing list, or blog audience? Would you like to do a feature, an interview, or post an excerpt? Please click here to let me know. There is a ton of material, including case studies, video, and pictures.
Upward and Onward
Thank you all so much for the last three years. It’s been incredible.

What a great way to start off the year, with a brand new mind, body, and soul. The book is packed with so much good stuff, the easy slow-carb diet, kettlebell swings, and the brilliant section on polyphasic sleep. I’ve tried many other diet & exercise programs, Atkins, P90X, etc, and this one is by far the easiest and most realistic to follow. All of the other programs make it impossible to go to lunch with coworkers or dinner with friends w/o feeling like a complete social outcast. Thanks for all your hard work and ignore all the haters out there, I am living proof that your $*** works!
15 minute female orgasms! On to Barnes and Noble now.. 🙂
yes, this might be the biggest chapter for book sale! 😉
after all who doesn’t want this skill!
OOOOHHH YEAH!!! Here it is baby! I can’t wait to read this. It better be as kickass as your first.
Pre Order Done!
Excited to read it!
Awesome. Ordered! I’ve been definitly looking forward to this one!
Great job Tim! Amazing title – so simple! Looking forward to reading this 🙂
Just bought two copies, got free shipping. not interested in selling the second but it will be a good gift! Can’t wait to get it and read it.
This is going to be a Bomb.
Title is spot on. If it ain’t broke…
Congrats Tim, I am sure it is great. I was wondering If it is available on Kindle or iPad now?
Hey Tim, Good luck on the new book. I’m looking forward to the read. I tried your weight lifting plan a couple years back, and enjoyed great results. Hope you have some MMA stuff in there too! Victor
pre ordered! can’t wait to read it.
Yay! I’ve been waiting for SOOOOOOOOOOOOOOOOOOOOOOO long. Thanks Tim, can’t wait to read it!
I’ll be ordering a signed copy the minute the direct deposit hits my account. Looking forward to this!
Hey Tim, is there no way you can offer some signed copies to fans outside the US? I’m in the UK and Barnes&Noble want $18 shipping, which if I’m honest, I’d much rather spend on an extra copy of your book. I can tell you now, a few people will be getting this book for Xmas from me!
You rock your readers’ world. Can’t wait to hold your new book in my hands. Congratulations!
Not to toot my own horn too much Tim, but after a decade and a half of non-dogmatic experimentation on myself and willing friends, you’re the only author out there (excepting Martin Berkhan I suppose) who I’ve always agreed with 100% on training and diet, and your fantastic results should be ample evidence for the skeptics out there. I’m really excited to see what can be learned from this new book and will spread the word far and wide. Thank you in advance for all the diligent work and for sharing so freely.
Any idea when the prerelease copies from the last book promo will ship? Great sales copy by the way, reminds me of the old school long copy landing pages minus the 10 pages of endorsements.
Looking forward to the book.
Ordered, looking forward to reading it.
same question as Freddie, really want a signed copy but don’t want to pay x2 the price for shipping.
Sorry to say. I’m waiting for the Kindle version.
This is the book I’ve been waiting for! Congrats on your second book. I hope it’s as successful, if not more, than the 4 Hour Work Week. After the book comes out I’d love to be a case study of some of the material, either to be posted on your blog or possibly an updated and revised edition down the road. Are you going to be looking into anything like that? Have a good one.
I’m having trouble ordering. They are trying to charge an extra $25.00!???
Can you please explain the $25? What’s happening, exactly? Int’l shipping, maybe?
Today your book is in the third place in the Hot Products at Alexa
I’m in the UK, but I’ll be ordering a copy for myself right now with expedited shipping. SO exciting about reading this and getting results!
I can’t wait to read the book. The running chapter should be really great to read since I’m reading up on marathon training information and tactics since I’ve just started training for my first marathon. Nice title and great cover, maybe I won’t have to hide the book’s title while reading it this time.
Can I preorder if I live in Mexico City?
Done! Two books ordered, very glad to help you out, its easy repayment to all the value you’ve brought me via your blog. Best of luck with pre-sales of the book!
Sounds like an interesting book – I really enjoyed the 4 Hour Workweek. But, I’m a 100% Kindle and iPad reader now. Is it possible to order Kindle versions today as well?
Already got the body, but still quite intrigued by the back cover description. I wonder if this information could help me making the basketball players I train more athletic. Looking forward to this!
Kudos from Portugal!
Thank you very much for this book. I was waiting for it :). I think I am the first one to make the reserve.
Do you plan to translate the book into Spanish?
Can’t wait for this book. Just bought 2 copies. Good luck with it reaching #1.
First let me start by giving you a super huge congrats on your book release!
Second, I’ll be sure to pick up a copy of your book. Sounds awesome.
Third, I’ve been on your diet plan for going on almost 3 weeks now. I haven’t been able to exercise as much as I’d like but hey. Who can…anyway, I’ve only lost about 8lbs but I have dropped two belt notches and I’ve had to buy new pants! I’ll be the first to admit I didn’t follow your suggestions exactly but I was pretty damn close! 🙂
Keep up the awesome work!
Congratulations Tim, look forward to reading!
Well done Tim 🙂
Hey Tim, haven’t heard anything about the advance copies for those who bought 4 or more of the revised 4-Hour Work Week a while back. You mentioned they would go out even before any media got their hands on it… that still happening?
Looking forward to this one!
Will it be available in electronic format (Kindle)?
Wow Tim, congrats on the newest book!
“How to produce 15-minute female orgasms” – and they say that a live of a researcher is dull 🙂
Great … I’m buying this book! I hope I can find some information in your book to cure a physical (pain) problem! If you find 2min of time please send me an e-mail, I would like to ask you a question about it.
I would post the direct link to the site but I guess it comes off as spam. But you can check it out by googling “paincenter.stanford” which will bring you to their home page. Do a search for “Human body + pushing the limits”
You will find a video about a woman that had pain for years that wouldn’t go away, trying many different types of massage, therapy, accupuncture, etc. But researchers at the pain center in stanford have found methods of reducing the pain by 50% which is about the same to what most pain medications will do.
It is what the Shaolin monks do so they can perform the physical feats that the average person can’t. They study them in the video. I’ve trained with them and they are truly amazing. A 74 year old master was breaking bricks and along with other things.
Check it out, it really interesting!!!
Hey Tim, Pre-ordered the book. The way I see it even if I only get one paradigm shifting piece of info from this book, it will have been worth the $20. Keep cool, this one is gonna blow up much bigger than 4HWW.
2 months and a half? I cannot wait that long, man. Wow.
But seriously, congratulations. The book will be successful, I can fully assure you.
I wanted to ask you, are you exploring any disease topics in the book, how to treat particularly, I am pretty sure you have the preventive part down.
Very excited to read this! Thanks Tim!
any word on kindle availability?
Just pre-ordered a copy. Better be signed when I recieve it come December!Thanks for the great value in your blog posts and previous book.
Your loyal reader,
Congratulations on the book and the abso-genius marketing! With an “ask” like that, the “answering” is easy!
Got anything in there on pregnancy and childbirth? (Maybe that’s a fine follow-up to the 15-min. orgasm.)
Thank you for continuing to dispel myths of limitation – about worklife and now, about the body! Thank you for affirming the amazing nature of the human being, whether you knew you were doing that or not.
I just ordered 2 copies 🙂 Look forward to Dec. 14th
I just pre-ordered it, I can’t wait to read it!
Just bought 2 copies via B&N. Looking forward to reading!
Hey Tim, I have the same problem as Freddie. I too would like to get hold of a signed copy, but the shipping to the UK is going to cost me $18. I’d much rather spend that on a second copy of the book for my brother. Any ideas?
International readers: we are able to pre-order the book. I just did from Mexico City!
Congrats Tim on your new best-seller. I know it will be one.
Pre-ordered my copy to Germany, hope to be one of the first guys over here. 🙂
Really excited to read it. Your last book has changed my life like no other piece of knowledge before.
I just pre-ordered, as you requested. I can’t tell you how excited I am to read your book! Is there a chance you could give us a sneak peak at 1 or 2 of the how-to’s in the book?
Just what I need to get rid of about 15 pounds. Can’t wait to implement your methods. Thanks dude.
Order in. I’ll schedule a break from my geoarbritrage to pick it up. Thanks Tim, I appreciate you effort.
Pre-ordered for Belgium 😉
Ordered. Pity we have to wait a few months, but still can’t wait to read it. Intrigued as hell with the intro you’ve given it.
I’m looking forward to tweaking the hell out of my body like my brain’s been tweaked since reading 4HWW. Good luck!
Order in. I’ll schedule a break from my geoarbritrage to pick it up. Thanks Tim, I appreciate your effort.
I Just ordered two copies! (Gotta love free shipping)
I’ll probably read the hell out of one, and attempt to keep the other in mint condition.
BTW Tim, after years in the making my 4-Hour Work Week influenced business is about to explode.
Done and done sir, definitely enthusiastic to support you in your sophomore effort. Best of luck.
Dec 14th shipping is perfect, I will be back home in NorCal from Peru for a month and have some time to read.
Looking forward to it.
btw, when are you headed back down here to South America again?
Pre-ordered! This shall be interesting. Congratulation on that Tim.
Does the preorder on Amazon.ca in Canada also include the signed copy? Great addition to your 4-Hour series.
First of all: congratulations on your new book! A new milestone in your life, I can imagine. I’m a big fan of your innovative and creative way of looking at things. You seem to look at the (old, ‘normal’) reality (work, weight, health) with a curiosity as if it were the first time you ever saw it: In your eyes a workweek of 50 hours looks like 4. This makes great changes possible. Thank you for it! I will order some copies of your new book. I really loved your last one. Keep up the good work!
Kind regards from The Netherlands,
Can’t wait, ordered and spares ordered as Christmas gifts, no doubt it will be awesome.
Ordered autographed book and CD. I’m a big fan of your 1st book, blog, and Random Show. I’m very excited to check out this book! Your detailed and thorough research skills combined with your reflective nature and willingness and ability to take risks make you one fascinating man. Thanks for sharing all your wisdom!
Yes! Finally! Eilis–What is this about 15 minute orgasms? Definitely checking it out.
I pre-ordered a small bunch, and I’d love to participate in a phone Q&A, but the form your assistant (I presume) has set up doesn’t fit international phone numbers. I hope it’s still possible to join in – anyway, there’ll be a non-working phone number on the entry having my email.
Best of luck, Tim, I’m really looking forward to this.
Congrats on getting the book done. Your first book changed my life… maybe this one will change my body. Keep rocking!
15 minutes for a female orgasm? If it takes that long, you’re doing it wrong! 15 minutes is enough time for at least 2 or 3.
Haha… I’m talking about DURATION.
Don’t be such a wuss Freddie and bite the bullet with the shipping! You’re getting a first edition SIGNED copy of this book in $’s. Go into Hatchards on Oxford and you’ll get a signed first edition for MORE! $18 for making your wife happy for the remainder of your life is a bargain!
31.00 USD = 19.6278 GBP
Congratulations on your new book. You are to be commended for the tremendous amount of work you have put into the R&D for lifestyle design and now into the human body. Having been introduced to you just prior to the launch of 4HWW your marketing strategies on how you amassed a huge following is an amazing case study in itself. It’s one thing to have a plethora of knowledge/experience and totally another to have the wherewithal and marketing savvy to spread your message and create community by challenging the status quo – such as you did. I’ve really enjoyed the insightful blog posts as well as the many fantastic resources. I look forward to reading the new book and if it’s anything like the four-hour work week I will be happy to endorse it…Talk soon
Best of luck,
I’m super pumped for you. The book looks totally fantastic.
I’ve pre-ordered two signed copies from Barnes & Noble. I’ll also snag a Kindle copy at launch.
A big congrats to you my friend.
Awesome. Just ordered mine. Can’t wait to read and evangelize.
I just ordered my copy. I read the teaser on the earlier post, but the new details sound like the book is even better than I anticipated.
Done – 2 books ordered – good luck Tim!
Already ordered, even though shipment costs almost as much as the book. I have a feeling that this is going to be BIG. Bigger than everything the world has seen so far in terms of book publishing and marketing. Tim – I’m sure this is going to work extraordinarly well – I’ve never ordered anything from the US yet – you are the first person who convinced me.
Great news! Just uploaded my screenshot.
Please fix the phone number fields. They don’t allow for either international numbers nor for cellphone numbers!
Very good news and an original title…..
Congrats with the finished product.
You can send me one, I will review it on my site for free 😉
All the best,
Congratulations on the achievement, Tim.
When you were out in Cape Town, I asked you what you would do differently to market the book, and as you said then, you’re more or less following the same path as you did the first time round. If it ain’t broke, right?
The 4-Hour Workweek was a revelation and strolls into my top 5 business books ever. I have no doubt you’ll knock this out the park, and even if I don’t follow through on everything I read, I trust it’l be a riot to read, nevertheless.
Does the “Sleep 2 hours per day” blurb refer to polyphasic sleep (i.e. “uberman” sleep?).
If so, did you try it?
I spent 4-5 months of my life addicted to the polyphasic pseudoscience pushed by internet communities and bloggers and essentially wasted half a year attempting to “adapt” to the uberman schedule. It was the biggest mistake of my life and it screwed over my health in remarkable ways.
I’m now a chronic insomniac, went through a suicidal phase, have little to no energy or sex drive… I’m slowly improving (doctors, therapy — I’m absolutely not kidding), but I wouldn’t recommend it to anyone. (My early 20s age may have something to do with my apparent susceptibility to chronic sleep deprivation).
Super job, Tim! 4HWW changed my life. Literally. I submitted contact information via your Google Docs form. I’m on board with your phenomenal sophomore effort! All hail capitalism…proceeds to benefit the organization you inspired me to start:
Love it! 🙂
Pulling out all the stops this time are we, loving it 🙂 Couple of copies coming to Finland, cheers!
So yeah, just ordered 2. It still counted out shipping cost and doesnt say anywhere that its signed :/
Only need 1x but i loved the fourhourworkweek and i’ll definitly find someone who can get one as a gift 🙂
AWESOME, I’m totally stoked!!
Thanks Tim! I’ve got a copy headed my way when it’s available.
I hope it’s worth it, since shipping to Holland isn’t that cheap 😛
Just ordered 2 copies!
One for me and one as a gift for a dear friend who lost some serious weight.
Loved the first book!
Checking your site regurarly for awesome tips!
And allready gained some serious Pounds on my skinny body in muscle by Just some “simple” tips from your posts.
Dude you rock!
thanx for the tips and some warm greetings from the netherlands … or should i say HOLLAND.. you been there on one of the coolest days..
Her majesty (orange) birthday party. so you probably know.
keep up those posts.
Sounds awesome. I hope it will be available for Kindle from day 1.
Looking forward to it. Ordered.
Done! Can’t wait to read it!!!
Awesome job Tim!
Done and done. I live in Korea so shipping is almost as much as the book itself! But (and let me guess that this is exactly what you want to hear) I am convinced it will be worth it judging by your first book and blog posts.
And how about for book number three? “The Four Hour Life” (A compendium of life hacks)
Bought a copy.
Are you interested / intending on organising referral sellers through your own website or similar?
I’m practising life mastery and doing the fitness thing the p90x way atm (which is tuff!). Shit, if I can do it in 4 hours, all the better!
Msg me if you’d like a copy of an ebook I am writing on other elements of life mastery.
What about those of us who got the 5 copies of your book last December? We still getting an advanced, signed copy?
Hi Aaron and all who bought 5+ 4HWW copies a while back,
Yes, yes, yes! Please look for an email from my assistant Amy today. Thanks again!
I can’t wait to get my copy from the last promo too! I’m so excited this is ready to drop!
Nice! Done & Done, sir… very much looking forward to it!
well done Tim! just ordered one… hope you blast up the best sellers list.
All the best from Ireland
Retweeted already, and two signed hard copies on order! And I’ll get my Kindle copy once the release date is here. I’m anxious to read about the 2-hr sleep per day.
You know, I balked at the price tag, thought I’d wait for it on Kindle, but then I thought, how much time and energy did 4HWW and this blog add to my life? How much did I benefit from Tim’s training recommendations, when I found that I could build nice muscles and strength in a month?
How much money have I saved following Tim’s advice from 4HWW?
I admit that I’m skeptical about some of Tim’s claims, and I wish some of his advice had more rigorous evidence to back it up, but I’ll give it a go.
I went ahead and ordered two signed copies. Looking forward to getting them!
