The New Book Unveiled: The 4-Hour Body (4HB)

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,, and these online retailers.

Thank you!

  1. Tim, I just pre-ordered your book and look forward to reading it. I have your other book too. You have a ridiculous amount of ambition and motivation. I don’t know how you keep it up.

  2. Hi Tim,

    Read the call for action via email subscription and being a big fan, I hit the link to buy – but I live in France and usually use for my purchases. Usually don’t get charged for shipping. Is it OK to buy through them? Will you not get “credit” for an purchase?

    I wonder if I would have trouble ordering for overseas through B&N.

  3. I read the 4-hour work week. Still working 40 hrs. 4-hour Body must be selling like hot potatoes…

    Why not 4-hour Language, 4-Hour IQ, 4 Hour Love, 4 Hour Psychologist, etc. etc.

  4. Just ordered! Stoked ! The signed copies are a nice personal touch, thanks for that, just another reason worth getting it here extra fast, international shipping costs be damned 😉

  5. Never pre-ordered anything before, so you really nailed the copy on this one. 😉 Really pumped up about this one! I am in quite good shape but I feel there is much more to learn, and goals to reach. Keep up the good work!

    Greetings from Sweden

  6. Big fan Tim. Ordered a signed copy last night and look forward to receiving it!

    One question: Do you explore which type of strength work is most effective at building muscle. Barbell training or something else?

    Thanks as always!


  7. Awesome! I have been waiting for this book to come for a long time! Can’t wait to read it. Now I finally know what I want for Christmas. 😉

    Nick, The Traffic Guy

  8. Thank you, Fred – and Tim!! Super big congratulations on the launch!! Can’t wait to see a real, live copy, and I’m already telling my world about it. Go you! 🙂

    1. Hi Karli,

      Really? That’s so odd. Here is the response I got from my publisher, and I will double-check again:

      “I just spoke with our B&N rep, who has been in constant touch with the buyer today, and both confirmed that consumers are NOT charged until the book ships and/or the ebook goes on sale. We just ordered a copy of the book so we could see the messaging on’s system, which says “your credit card will be charged when your order ships”.”

      Will do some more detective work.

      Thanks for the comment!


  9. You just made me make an inpulse purchase: 2 signed copies ordered and I can’t wait for delivery. Your first was great, can you duplicate?

  10. Hey man,

    Just ordered the 5 books, looking forward to the teleconference and getting access to all this crazy knowledge. I lost a bunch of weight following your blog post (204 pounds and 17 or 18% bodyfat to 170 lbs and 9%) and am going to submit some pictures.

    Peace bro, and good luck with the launch


  11. Hey Tim!

    Still awaiting your reply on my earlier post (attached again below).

    Have already pre-ordered 1 book with the fear that I might not only loose out on the telecon opportunity but also the specially signed books by you!!! 🙂

    Please let me know so I can order 4 more books 🙂 Thanks.

    —– Earlier Post Below —–

    Hi!!! Wanted to know about having a 1-2 hr telecon with you on Lifestyle Design:

    1) Will everyone ordering 5 books or more get the opportunity??? Or few select people from the total?

    2) Will this opportunity be applicable for international readers as well? (Im from India).

    Pleaseeee clarify ASAP as we gotta order before 12am!!!!


    1. Hi Manan,

      Thx for the comment. Here you go!

      1) Will everyone ordering 5 books or more get the opportunity??? Or few select people from the total?

      TIM: All who buy 5 or more.

      2) Will this opportunity be applicable for international readers as well? (Im from India).

      TIM: Of course! You’ll just need to call in. Skype should work fine, I’m guessing.


  12. Tim,

    Done and done! I’m looking forward to reading my copy on my roadtrip from Atlanta to Tucson. The release date is perfect timing! (Although I’m sure plenty of y’all out there would have preferred it to be sooner). In any case I’m stoked!


    I didn’t read through the several hundred other comments to see if someone already responded to your issue, so I’m sorry if this explanation is redundant.

    If you clicked on the free member shipping option, B&N would have added the $25 membership to your cart.

    If you want the free shipping and are already a member, scroll down the checkout page until you see a box in which you can enter your membership number, which is located on the front of your card.

    Another window will open in which you can select your shipping preferences.

    Good luck!

  13. Hey Tim, some odd months ago you twittered that you were looking for a certain stuntman’s contact info. I was the one who sent that in.

    Can you tell us if there will be any non-physical distribution of this book!? I travel very extensively and simply don’t want to add any books to my already tight kit. I will pre-order a physical copy just as I did 4hww, but only if its the only way.

    Please let us know. THX!

    1. Hey Joel,

      I remember and thanks again. Yes, there will be digital versions. I’m not sure on the timing, but they’ll be there. The hardcover is probably the best format, if possible, just because there are something like 200 illustrations/pictures.

      Travel safe!


  14. Aw Maaaannnnn! I’ve gotta wait till December? i want to get my body right NOW! LOL

    No huge improvements (still lacking discipline so far) but I DID go down a belt size in a few weeks following your Slow Carb advice. Even though I SWORE I’d never pre-order a book again due to several bad experiences, I’ve ordered The 4 Hour Body. Keep up the good work.

  15. Ordered a copy from B&N.

    After reading your “From Geek to Freak” blog post at least 20 times,

    I look forward to reading the “4 Hour Body” at least as many times.

    This is my first time purchasing a blog-promoted book as well.

  16. Tim,

    Congratulations on the book release. I know that this a topic you are passionate about and I hope that it is just as successful if not more successful than 4HWW.

    I’ve taken some of your fitness hacks and used them in my workouts with great results. As someone who grew up being that pencil thin guy, I love seeing people from high school who are amazed at the change. Can’t wait to see what the new approaches you talk about in 4HB. Maybe I can turn heads all over again.

    Already pre-ordered a signed copy and can’t wait to see what your next project brings. Best of luck in your endeavors.

  17. Tim- Placed an order for a couple of books that I plan on sharing with family and friends. Although I’m not willing to reduce the big “O” to only 15 minutes, the rest of your work looks groundbreaking! Keep it up and remember, if you can’t run with the big dogs then stay on the porch!” 🙂

  18. Ordered one for Canada, 6.48 shipping is not bad. The Canadian price will likely be closer to $20 anyway, for those of you doing the math.

    A small thing to do for you Tim, I really appreciate your work and you as a person, you are positively affecting many people.



  19. Pre-ordered on the German amazon page, to be delivered to the UK,

    right in time for Christmas.

    Would have loved a signed copy, but shipping cost and time is just too much.

    Thanks Tim for all your great work, really looking forward to some more tricks to tweak my body and especially my mind!

  20. @Bernard,

    Given that Tim went with my prediction of the four hour body as the title of this book, I would suggest he is building the 4-hour brand.

    Most of the readers on this blog read for all aspects of lifestyle design, including the several posts on body enhancement and development.

    I would suggest bookmarking, which is a domain Tim uses as a redirect to this site. My assumption is that as the brand builds, that will become the main blog page with redirecting to it (note: Tim uses when commenting on other blogs and in videos, likely for this reason).

    Smart move Tim, well done and I’ll try to order a copy of the book now 🙂

  21. 5 copies locked in TF! Have you read a book called synchronicity? Can’t remember who wrote it and at the time I remember thinking what a load of S&%t! ….However, almost every time I read one of your post I find an answer or at least great inspiration to a problem I’m dealing with…synchronicity! Cheers tim

  22. Tim- Thanks to your speed reading tips I ordered 5 copies before I even finished reading the post! Your first book has changed my life, so this one can only be better.

    I can’t wait for the upcoming teleconference for those ordering more than 5 books, and just have two quick questions:

    1) Will we be able to post questions beforehand that you can try to address?

    2) Will you lend advice or tips on muses, marketing, & related lifestyle design topics beyond what’s in the book?

    As always Tim, excellent work. Portate bien & cuidate mucho


  23. Hey Tim! Just ordered my copy and can’t wait to read it! 4HWW changed my life and the way I think forever! I’m looking forward to how this may do the same for me in these areas of life.

    By the way, it was nice meeting you in Willow Glen not too long ago. Hopefully we’ll bump into each other again soon. You’ve been a huge inspiration to me and as a result I’m about to launch a marketing company based around the principles you teach in 4HWW. Can’t wait!

    Best of luck with your book launch as well, but I’m pretty sure you don’t need luck at this point 🙂


  24. Man, I don’t know if you can hack the human body as you say… it’s rather hard to believe…

    What I know is that I loved your first book and that you do know how to create expectation and you do know how to sell your products.

    I just pre-ordered 2 copies O:)

  25. Hi Tim,

    Really looking forward for this book! Exactly my taste, I can finally become Batman!

    I also noticed your last words, and wonder if you may be a Metal Gear Solid-fan? If not, look up the MGS soundtrack “The Best is Yet to Come”, a wonderful piece!

  26. Tim if it’s half as good as the your first book, it’ll be worth it. Your book motivated a buddy and I to write and start our business and book 12 months ago can’t thank you enough. Also can’t wait to tear one of the 5 copies I just ordered!

    Tim – Anything on digestion? As far as body hacks go it seems like it all starts with making sure you have and are getting everything you need from your diet! Hope you got something on chronic ankle sprains too!!

  27. Hi Tim- this book would make a perfect piece for my blog- I’m a health psychologist and love and intimacy coach and write about healthy sexuality/innovative stuff ( I just did the form for the media piece). I’m in the process of completing your first book (-in the midst of market research for my muse, thanks for the ideas on marketing, grad school taught me nothing about how to market a product!) I ordered 2 copies, may want to take your teleclass though – if we can ask questions. If so, am I able to edit my order to 5 today? Thanks!

  28. Hey, Tim!

    When can we expect confirmation on receipt of our 5 books receipt?

    Sorry, just eager! I didn’t get any email(s) confirming my submission or from Amy. However, I am sure she is swamped. As it appears like you have had sooooo many people take you up on the 5 books! (AWESOME in so many different ways — I can’t imagine movie sales, etc. if actors and actresses would do the same thing!!)

  29. Congratulations Tim!

    Looks like your new book is a hit already! 😉

    Pre-ordered my 3, can’t wait to spread the book to friends. If it can do any more for me than the Slow-Carb diet and 4HWW already are then it will be priceless.

    What are you doing to celebrate this massive number of pre-orders?

    Will you be doing a book tour? Through Canada?

    Good luck and Alles liebe!

    PS LOL to the guy who asked about a video tutorial for the orgasm. You made my day. 🙂

  30. Hi Tim,

    just ordered my copy. I’m a sports chiropractor and exercise physiologist who works a lot with athletes from weekend warriors to pros. Excited to see what you put in about C.A.M (acupuncture, chiropractic, active release therapy, graston, kinesiotaping etc) for becoming super human!

  31. Tim,

    Just pre-ordered 5. Can’t wait.

    I also did the Google Docs media thing. My list is at around 80,000 now. Last month I launched a product which has grossed over $2 million already, and I doubt I would have done it without reading the 4-hour work week. It was the kick up the ass I needed. Better yet, I’m only 19!

    Either way, a blast to my email lists is the least I can offer. We (or myself and your assistant – I guess you’re super busy!) can discuss the specifics via email. I can hook you up with a few more of the “big dawgs” with even bigger lists than mine, too. Hope to hear from you.



  32. Just pre-ordered your latest book from B&N. I’m a huge fan of your book, your blog, and Random Episodes w/ Kevin Rose. 🙂

    I’m looking forward to reading your new work. Thank you for being an inspiration and beacon for so many of us!



  33. Tim, five books ordered and waiting to be sent to Hokkaido, Japan. The other four books will make fine gifts to worthy family and friends.

    I’m very much looking forward to the telephone Q&A as well as reading your new material. I’m trying to think of a question that will be beneficial to us both – I’m looking forward to making you think!

    The 4-hour Work Week totally changed the way I worked – I guess this book will change the way I live. As a keen strength trainer and life hacker, I’m looking forward to this book enormously.

    Wishing you a very successful book launch.


  34. Hey Tim,

    Just added 5 books to cart, and B&N wont ship internationally,

    its states “Your order is now shipping to an international destination; please choose an appropriate shipping method.” and there is no other “appropriate” method? I have cash in hand my friend ready to buy – any thoughts?


    Simon (Melbourne, Australia)

  35. Ordered with pleasure. I’m not sure when I will get my hands on it (I live in the England but will be travelling when it is posted) but I am certain it will be worth the wait.

    Thank you for continuing to inspire all of us and for inspiring me as a writer and perpetual adventuring child myself. The world needs more people who work less and play more.

    If you ever establish a university of play with special classes for writers and adventurers there would be a queue out the door – with me elbowing my way to the front.

    safe journeys and big fat adventures

  36. Congratulations! What a natural and fabulous title. Cannot wait to read it! This book is a bit of a dream come true for me. I feel so ecstatic that someone with a proper budget actually chose to apply their funds to an undertaking like this. Testing, testing, and more testing. HOORAY!!!

    5 copies down for me and some lucky tbd friends!

    I remain grateful for and still so treasure the signed copy of your revised 4HWW you sent me. Looking forward to more encouragement smiling at me from my shelf.

    On a practical note, I also have high hopes for the info in 4 Hour Body to help my situation. I have needed my body hacked for years! 😉 and have been trying to hack it myself with middling success, using an equally beleaguered Lyme brain to do it. btw, any suggestions for outsourcing and/or hacking all aspects of some neurotoxin-besotted grey matter, on a no-budget? Brain is now my biggest barrier to the 4HWW. It’s so bad, I have spent the last 2.5 hours just figuring out how to buy your book, make a screen shot, and write this post. Not kidding. I now read at 70 wpm for any comprehension whatsoever. So frustrating!!!. The anticipated round-the-corner cure has been really slacking about on the other side of that infernal corner… So, I am just taking on symptoms.: pain and brain.

    re: brain. Here’s the laundry list of attempted solutions: truckloads of various neuromins, homeopathy, meds, neuro detox strategies, neurodevelopmental movement, dietary approaches, neurofeedback, metronome therapy, attempts at meditation, exercise, air filters for molds, etc. etc.

    oh dear life hacker of life hackers, any other subtle tricks up your sleeves? Perhaps there’s a brain chapter in the book… ?! Or ideas for no-budget outsourcing of the brain?

    re: pain. FYI: after 13 relentless years of it, and the ensuing bankruptcy from flailing about desperately with every allopathic and alternative promise of relief that crossed my path, my pain issues have been largely resolved by…. titanium, magnetic and infrared products. Even tachyon products have been shockingly effective, and they are quantum-goofier than anything else I have in desperation tried. Wow, who knew? not my ND’s, DC’s, PT’s, MD’s, LAC’s, rolfing/gyrotonics/feldenkreis practitioners, etc., ahem…. Ah, the information game.

    And so… back to the book. I close by sending you my very best wishes for yet another 15 minutes bursting with authorly fame, Tim! Thank you for taking on life in such a brilliant way, and for so generously sharing the spoils with your readers.



  37. Like some of the others here I wondered about the the confirmation email not stating hardcover-signed as the B&N website displays. One way to check is to look at the isbn number within the order tracking application. Signed ends in 197 and the unsigned ends in 630, I believe. Ordered two and the 4hww as well since I’ve read it twice and don’t have my own copy. Kindle just doesn’t cut it for some things.

    1. Yep, totally true on ISBN. Thanks for the help with clarification! This hardcover also has 200+ illustrations/pics. Digital might work, but I can guarantee hard copy will.



  38. Got my order in. Nice timing by the way; this is just a guess, but is the idea to make people worry that if they don’t pre-order, they may not get a copy by Christmas?

  39. well that’s buggered up my ‘5 Hour Body’ book idea!…

    Good luck with that Tim – looking forward to reading that soon

  40. OK, I am really interested in buying your book but I have a question about the two hours of sleep before buying it. Is it possible with the technique you are talking about to sleep everyday 2 hours?, or it’s a solution for random moments where you need to do something and you simple don’t have the time to sleep. I always thought that sleeping is a waste of time and if its possible two sleep two hours everyday I would go ahead and buy it next second to be one of the first to find out the technique!!

  41. Ordered two of the signed copies for free shipping to a PO Box in the States. May still order a third copy from a Canadian retailer to get it more immediately in Canada. My bet is that in spite of there being 3,000 signed copies, almost no one will keep them in unread condition, and they’ll still up being collector’s items.

  42. Hey Tim!

    This looks fantastic… I know you’ve talked about this for a long time and I think the final result will be great.

    I’m living in, and I’m sure I’m not alone, the U.K. … what options for signed copies do we have since if I order for friends/family as Christmas gifts, it’s hardly likely they’ll arrive on time.

    Any UK-fan options? 😉


  43. OMG Wow! This Book Looks Like The Holy Grail! Thank You Tim For Your Incredibly Obsessive Persuit In Finding The Answers That Help So Many People Like Myself. Your first book was amazing for me, like a book of revelations haha. The second book is bound to be a hit. I’ve pre-ordered and cannot wait for it to arrive through my door. My birthday is in Dec, so what a great present to myself huh? 😀

    I’m so looking forward to reading about how to rapidly lose weight, increase muscle and the female pleasure part lol.

    Thanks Again For Your Significant Contribution To My Life & To Others.

    Best Wishes,

    Darren 😀

  44. Incorrectly placed previously!


    The timing of your new book is perfect-almost anyway. Please let me explain.

    About 6 month’s ago I read a book about RFL (Radio Frequency Lesioning) for my back pain. The author (a doctor) suggested losing weight and getting some exercise. After 51 years, all of a sudden it was sound advice. Sound advice that worked.

    I went on the Ideal Protein diet which, coupled with some exercise, allowed me to lose almost 30 pounds. My 3 trips a week to the gym (3 sets of 15 slow reps) transformed my body. Yes-favorably. And I have managed to keep my weight stable ever since. However, after a few months I started to develop shoulder and elbow pain. Some cortisone used to relieve it but not anymore. Energy was fading. Two young children. Life.

    I started to look into “life extension” types of products. Cenegenics? Too expensive for me and too many shots. With the help of a local life extension physician I was just about to start taking armor thyroid and use testosterone cream followed by a post cycle including clomid and ZZZZZZZZZZZZzzzzzzz.

    Are you still there? I too am bored. And scared!

    I will wait for your book. I am 51 years old and look forward to communicating my experience with you and others.

    Thanks for being a guinea pig for the rest of us.


    Four Hour Johnson

    PS. I bought 5 books as requested. I am planning on the possibility of you changing my life again! Looking forward to your call!

  45. Pre order done.

    Happy to help you out Tim you have changed my life, your first book is one of the greatest books of all time.

    Planing my first vagabonding trip around the world trip with no drop in my monthly income while I am away, living the dream and its all thanks to your book.

    Good luck with your new best seller.



  46. Tim,

    I greatly enjoy your blog and loved Four Hour Work Week. Will you be releasing a PDF version of your new book? My own lifestyle redesign begins October 17th with a one-way ticket to Europe and no set itinerary, which makes a pre-order a bit tricky. 🙂

  47. Tim,

    I am for sure buying one.

    I teach out of your 4 hour Work Week book to businesses.

    This is exactly what I need.

    Thanks for all your work man.


  48. I ordered mine today…can’t wait to read it! I wish I had it now, I am signed up to run a half marathon a month from today and am way behind on my training. Keep the great tips coming!

  49. Pre-ordered my copy just now. Been a fan of your blog and also loved the 4-Hour Workweek (bought both the original and the revised edition) and I can’t wait to read this one!

    Thanks so much for all the inspiration and knowledge! 🙂

    – Ray

  50. Congratulations, Tim!! My husband and I are so excited for you and your new book. We were going to order one, but loved your suggestion for giving it at the Holidays. Plus, we wanted to support you, too!

    Best of luck! We know this will be an amazing hit.

    What a great day for you!



  51. Tim, quick questions:

    1) If I order 5 copies from, does it count towards the live Q&A?

    2) In the book, do you discuss anything relating to enhancing cognitive performance?

    I remember in a video (somewhere on vimeo) you suggested doing neck exercises to increase blood flow to the brain. Is there anything specific on this, or does the advice for hacking your body indirectly include the brain too?

  52. Tim – Congrats on completing another book. It sounds interesting. One question, with the info on testosterone and sperm count, it sounds more geared towards men than women. Or, is there also info geared towards women and their specific hormone issues (like menopause)?

    1. Hi JoAnn,

      There is nothing on menopause besides some longevity discussion, but I would say 50% of the case studies are women. Plenty for the ladies!


  53. Hi,

    just wanted to say that it says i’m not eligible for free shipping

    Your order is not eligible for FREE Shipping.

    They see I need a membership, and although my order of two books is more than 25 I can only select shippings that cost 18$ upwards.

  54. Hi Tim,

    Bought seven in two different purchases, then went to my husband’s office (he’s a doctor) and have started to spread the news. It will be rather amusing to see what he thinks when he reads your book :-).

    I couldn’t get a screenshot of the purchase. Can I forward the receipts to your assistant by email to get the Q&A?

  55. Hi Tim,

    I was incredibly excited when I looked at the RSS feed and saw your book was coming out. The 4HWW changed our lives forever, and I’ve never looked back. We started our own business in May of ’09, and now we are free to live the lives we’ve always wanted.

    The next step was taking a serious look at our longterm health. I was following your “slow carb” diet for awhile, and just implemented the “Paleo Diet” because of this blog. I’m already down 10 pounds of fat and haven’t even started exercising too much yet.

    I was getting tired of scanning through the blog searching for nuggets of wisdom and in your posts and in your comments, now it will all be easily accessible in a bound copy!

    I am convinced this book will do for my health and physical well being that the 4HWW did for our business/personal lives.

    Good luck with the pre-orders, and thank you again for everything!

  56. Hi Tim,

    I admitted to my wife that I have a ‘man-crush on Tim Ferriss’, she scoffed and suggested that I be happy with the free copy I’m getting from your Extended Edition offer. I told her that she’s right and then proceeded to order 3 more copies of your new book without her knowing. They’ll make great gifts which she can’t deny.

    Your book and your blog encouraged us to travel to South America with our baby (then 8 months old) for a total of 2 months and was a great experience. Thanks so much for all of your hard work (past, present & future)! My family wishes you great success with your new book, you deserve it! We’re looking forward to following your experiences for many years to come! Cheers!

  57. Unfortunately 3,000 signed copies doesn’t make the signed copy ‘unique’ or ‘rare.’ If it was like 300 signed copies, it would of been a lot more attractive. Needless to say, I will still probably buy a copy down the road and support! Glad to see it out.

  58. Ordered my 5, perfect x-mas gifts.

    I also dislocated dozens of times — there is fabulous arthroscopic surgery now — I got one side fixed. I highly recommend it.

    All the best with this venture, I am sure it will be a great success!

  59. Hey Tim, unfortunately the B&N website has an error that doesn’t allow international orders to go through … looks like I miss out on a signed copy!

  60. Ordered for Russia!

    Tim, you have many followers and fans here. I hope Your new book will appear translated in Russian soon. Meanwile I’ll read it in original to practice my English.

  61. Pre-ordered 5 Copies from Barnes and Noble (a book like this is a perfect Christmas gift for friends).

    Looking forward to reading it.

    Thanks Tim!

  62. Just ordered two, figure I can find someone to give the other copy to for Christmas. I am glad to see the countless notebooks you own come together and create what I am sure will be another ground breaking book. I just hope there weren’t 3k already ordered before me.

    On that note, could you do a post on how to handle enormous mind-numbing tasks like signing 3,000 books? Can’t exactly use assistants on that one.

  63. Totally psyched! Long-time follower of your writing, can’t wait to put some of the rehab knowledge into practice with my clients once I graduate massage therapy school.

  64. Just ordered five for the cause!

    The 4hww literally saved my business a couple hundred thousand dollars last year… which in turn… literally saved my business!!

    So it was the least I could do!



  65. Hey Fonzie;) Looking forward to the book. Maybe it will be Rose’s fave book in an upcoming random episode. I picked up 5 copies. Looking forward to the call later. Thanks for always putting out great stuff!!


  66. Hey Tim ordered 2 last minute copies, appreciate the interesting info you always post up on your blog. Thanks for putting in the effort. good luck with the book launch!

  67. Yes, it’s available on Kindle for preorder if you search on

    Silly people, try searching rather than asking strangers in a comment stream.

    (Oh, yes, I preordered for Kindle)

  68. Love the knowledge you have Tim! Just ordered 10 books. I wanted to let you know that I am from the bay area, but I am writing this in Lima, Peru right now because of your book 4HWW, which showed me a glimpse of vagabonding. Soooo new to Americans, but according to so common to Europeans. Just visited Iquitos, Peru which is in the Amazon jungle and stayed at a shamanic village for 2 1/2 weeks. Taken some incredible medicinal plants and the insights I´ve gotten from them are incredible. Thank you thank you thank you. Oh, this is while still making money back in the U.S to cover for the cost of this trip also. =) If this new book is as good as your first book, it will do manicently well. Thank you!

    1. Wow — congratulations, Stephen! I’m really hoping to get to Peru. This comment might seal the deal 🙂

    Ordered a dozen 4HWW’s for Christmas a few years ago and just ordered 6 of your new book. Got the screenshot taken on my iPad but the submit button won’t engage when I try to attach it to meet the midnight deadline. Will send again tomorrow a.m. When I have access to a PC. Hope that still counts! very excited about the book. Just scrolling through Pulse and there it was! Can’t wait but hope you cone out with a vook version at some point too.
