After holding off for nearly two years, I’m posting this because too many people have asked for it. The lasses should read it, too, as the same principles can be applied to bodyfat loss.
I weighed 152 lbs. for four years of high school, and after training in tango in Buenos Aires in 2005, that had withered to 146 lbs. Upon returning to the US, I performed an exhaustive analysis of muscular hypertrophy (growth) research and exercise protocols, ignoring what was popular to examine the hard science. The end result? I gained 34 lbs. of muscle, while losing 3 lbs. of fat, in 28 days.
Before and after measurements, including underwater hydrostatic weighings, were taken by Dr. Peggy Plato at the Human Performance Laboratory at the San Jose State University, and I had blood tests taken on September 30 and October 20. Though this ridiculous experiment might seem unhealthy, I also dropped my total cholesterol count from 222 to 147 without the use of statins. No joke.
Here are a few comparative shots. Oh, and I forgot to mention, all of this was done with two 30-minute workouts per week, for a total of 4 HOURS of gym time:






How did I do it?
First, some select stats on the 4-week change (9/21-10/23):
Bodyfat %- 16.72 to 12.23
Suit Size- 40 short to 44 regular (measured at Brooks Brothers at Santana Row in San Jose by a professional tailor)
Neck- 15.8″ to 18″
Chest- 37.5″ to 43″
Shoulders- 43″ to 52″
Thigh- 21.5″ to 25.5″
Calf- 13.5″ to 14.9″
Upper Arm- 12″ to 14.6
Forearm- 10.8″ to 12″
Waist- 29.5″ to 33.1″
Hips (Ass at widest)- 34″ to 38.23″
Here are the six basic principles that made it happen:
1. Follow Arthur Jones’ general recommendations for one-set-to-failure from the little-known Colorado Experiment, but with lower frequency (maximum of twice per week) and with at least 3 minutes between exercises.
2. Perform every repetition with a 5/5 cadence (5 seconds up, 5 seconds down) to eliminate momentum and ensure constant load.
3. Focus on no more than 4-7 multi-joint exercises (leg press, trap bar deadlift, overhead press, Yates bent row, dips, incline machine benchpress, etc.) and exercise your entire body each workout to elicit a maximal hormonal (testosterone, growth hormone + IGF-1) response.
4. Eat enormous quantities of protein (much like my current fat-loss diet) with low-glycemic index carbohydrates like quinoa, but drop calories by 50% one day per week to prevent protein uptake downregulation.
5. Exercise less frequently as you increase strength and size, as your recovery abilities can only increase 20-30%, while you can often increase fat-free muscle tissue up to 100% before reaching a genetic set-point.
6. Record every workout in detail, including date, time of day, order of exercises, reps, and weight. Remember that this is an experiment, and you need to control the variables to accurately assess progress and make adjustments.
For the ladies not interested in becoming the Hulk, if you follow a “slow-carb” diet and reduce rest periods to 30 seconds between exercises, this exact workout protocol can help you lose 10-20 pounds of fat in the same 28-day time span.
Once again, questioning assumptions leads to the conclusion: less is more. Detox from TV twice a week and put in your 4 hours a month!

this has got to be a lie. i dont care who you are that kind of gain in that short of time and with so little time in the gym is impossible even on steroids. The most I have ever gained in that time period is about 7-10 lbs. and that was when i first started, Im sorry but this is highly unlikely. arnold Shcwarzeneggar(forgive me for probably butchering his name) was known for adding an inch in a month and it is thought of as almost impossible. one inch is about 10-15 pounds of muscle. sorry bro but please dont get these peoples hopes up. you cant gain 34 lbs in 4 weeks. Impossible
To Everyone who is saying that he just shaved his chest hair and put some pro-tan on, you obviously are ignorant. Now I'm not saying I fully believe this method of working out, but the before and after pictures were taken at two different times. For example, the lighting in the pictures is different and there is a shadow in the before pictures. Plus his overall build is bigger in the after. Although they were taken at different times, it seems like he wasn't even flexing in the before pictures. Me personally I don't think an hour a week (especially only two days) would be sufficient for a gain like that in one month
Please don't comment until attempting. This is my 3rd comment on times site. 2 here and 1 losing 20bs in a month. YES IT WORKS. how quickly people are to judge something they've never tried and how quick they will regurgitate some obscure harvard medical study about how it's impossible to add more than x lbs Ina lifetime etc etc. I have twice added over 30lbs of muscle in under 1 month. 2 yrs ago I went from 183 to 205 my heaviest/fattest I've I've been I didn't look or feel sexy so I then dieted losing over 20lbs in 30 days getting down to as low as 179lbs and 16.8% bf. that was day 1. I spent the next 30 days going to 18lbs and 9.8% bf. that transformation equates to losing 12lbs of fat while adding 22lbs of muscle in the same time period. So before u run ur mouth and say what is or isn't possible, try it first. You may fund yourself wrong and fit rather than right and fat!
Hi Tim, firstly thanks for everything, but i was wondering whether you had any experience with how well this works while on the keto diet? Thanks, Koray
People are so predictable on naysaying. So easy to judge sitting in your chair. One should do first then comment later.
So disappointed in this article Tim. This is physically impossible without exogenous compounds or substances. Thought you were more honest and genuine than this. Source: I'm a bodybuilder. Yes I'm a naysayer, and yes I'm more qualified then all of you trying to refute my argument. I really looked up to you. Not anymore.
Found this on wiki. Might of used steds on this experiment Ferriss has acknowledged using steroids, specifically "a number of low-dose therapies, including testosterone cypionate," under medical supervision following shoulder surgery, as well as using "stacks" consisting of testosterone enanthate, Sustanon 250, HGH, Deca-Durabolin, Cytomel, and other unnamed ingredients while training.[94]
I have a few questions from a girls persepective – 1) Are the supplements you have mentioned in the book required to achieve muscle growth or would I be able to achieve that solely on exercises and slow carb diet? 2) You mention to reduce rest period between sets from 3min to 30 seonds between each set – would I still be able to achieve muscle growth? My goal is gain muscle. I am 55kg and 164cm tall so I don't want to loose weight but I'd like to see more muscle growth while still not being bulky. 3) What happens after? Can you just continue to exercise twice a week with the slow carb diet to maintain muscle and not loose it? Do you keep adding weights? Confused as to what happens long term.
I have no huge problems with the workout described. I do however have huge problems with the claimed results in 4 weeks. There is literally no way that it is humanly possible to gain over 30 pounds of muscle in four weeks. Just think of it from a food intake perspective. Over each of the 28 days you will have had to eat more than a pound of food that you didn't burn off. AND you will have to have kept that weight as muscle. Not possible. Furthermore, the pictures don't even show a gain of over 30 pounds of muscle. He's not flexing in the first set of pics. He also shaved and put on tanner for the second pics. The pics also aren't the same scale. He's definitely in better shape in the second set, but that's not 30 pounds of muscle. It's really somewhat irresponsible to let people think this is achievable. Set realistic goals for yourself and stick with a workout. You have to walk before you can run. Get in a routine and you will be healthy for life.
I don't even know if this is the right place to post this, but I just wanted to say thanks Tim for a great programme (Occam's Protocol), and share my results. I followed Occam's Protocol to the letter for six weeks and gained 6.5kg (14.3lbs) while dropping my body fat from 13% to 9.16%. I know, it seems crazy that you can do so little in the gym and eat so much (I also drank a litre of raw milk every day) and still gain mass while losing body fat, but I tracked the data and that's what happened.
Complete BULLSHIT
30 pounds in one month…. so basically it should only take 3 months to get on stage with Mr. Olympia….. seems legit lol. A pound of muscle a day… not EVEN possible with the fattest stack of steroids. And the diet too… hilarious. You'd have to eat 3500 calories on top of your maintenance, somewhere close to 6 thousand calories a day AND not gain a pound of fat. I used to wonder why these scam artists keep trying to spread this nonsense and then after reading some of these comments I realize that some people actually believe this is possible. Just mind boggling how people can be so out of touch with reality… completely blows my mind.
Why is there always a book for sale? Next book for Tim: "The 4 hour hunchback to hot stud programme"
After trying a lot of other of your awesome lifehacks, I'm currently on this one. Today I did the first session according to your book 4HB. I'm fit with pull-ups already, but I have a problem with the "close-grip supinated pull-down x 7 reps (5/5 count)". The muscles that fail first are the ones in my forearms. Meaning I can't hold the grip with the hands any more, but still have lots of reserves with the muscles that actually pull down the bar. So I don't get to the point where I actually train until those targeted muscles fail. What can I do? (I'm weighing 165 pounds and I'm able to do the 7 pull-ups with the 5/5 count with a weight of 200 pounds. Then my grip fails, but I could actually do more reps with the rest of the muscles.)
Hey Tim, I'm reading your book and I'm confused, you say that you did the 10 exercises you listed for the experiment, but then later you have the A and B exercise sets. I don't know which to do, the 10 exercises you did or the A and B. I'm going to do this for an acting role, thanks Tim.
From what I understand, Occam's protocol uses 4 exercises total and two workout days a week doing 2 exercises each day. Tim says to fight the urge to do more exercises because this is the minimum dose you need to get the results. However, with Geek to Freak, he states to use 4-7 exercises. Wouldn't doing more exercises defeat the purpose of minimum effective dose? I'm confused.
Any lean red meats will work great for building muscle. Having a couple of servings per day. Red meat is definitely on the top of the list of foods that build muscle. It would be even better if you could get grass-fed red meat to a local farmer. Check around and you can find one. Tastes great too! http://nitricmaxmuscledenmark.com/
Can you post a workout example for one week as a reference?
How many days (if any) before the first workout should I start eating like crazy?
Looks like he got shorter too LOL!!
I love how when you click on "a little known Colorado experiment" it directs you to a bodybuilding website with unsupported gibberish that trys to get you to buy a $47 dollar product.
Hi Tim, Just wanted to say something here so I could apologize for my fellow human beings being so negative in the comments. I love your posts and tweets, but I rarely comment on them. Please keep in mind the bias of negativity on the internet. Love your work dude, and thanks for the post.
I just started this routine today and after my morning supplement and first meal supplement I am noticing that I am super hot. My skin has gotten really red and I kinda feel like I am on fire. Has anyone else experienced this? Am I dying?
From the comments, it would appear that Tim Ferriss is a genius. He has successfully duped over a thousand people into actually believing this is legitimate, and in doing so helped sell more copies of his book and put more money in his pocket! To all the people who say: "You don't know until you try it!" My only question to you trolls is: "Do You Even Lift, Bro?"
The Colorado Experiment was a hoax. Bill Starr of Iron Man magazine wrote an article on Casey Viator along with Arthur Jones, and revealed the truth to whole thing. Casey was being paid by Jones but eventually left to join the Weider organization.
I am using a herbal formula testosterone booster containing ashwagandha, mucuna pruriens, gokshura, Chlorophytum borivilianum. I find fascinating the idea of herbs working together in synergy, my mood is better and I have great stamina and energy to get my work done and to make my wife happy
I dont understand, what is the workout routine? I read the whole article on the colorado experiment and it didnt tell me anything about what the routine actually is.
All he's done is shaved his chest and got chubby
I thoroughly enjoy Tim Ferris, but this article is just plain disingenuous. Firstly, Tim added muscle that his body previously carried, which is a far faster process than building new muscle on a beginner's frame. Secondly, Tim could easily have used dehydration in the "before" shot and super-hydration for the "after" shot to boost his "lean mass." This practice can account for dramatic changes in bodyweight over the course of 2 days or so. The idea that anyone can follow these "six basic principles" and achieve similar results is ludicrous.
It was noted for those who don't want to " become the hulk" lol but is the slow carb diet what tin used during this ? IF someone can clear iffy I would be very appreciative
Tim – Love the 4HB! and the 4HWW of course! (The 4HC is on deck… used it for a number of recipes already though!) In regards to the increased caloric/protein intake, I was wondering if there were any specific precautions to take when coming out of the G2F bulking program as it relates to diet? i.e. cutting back to a simple SCD immediately, maintaining, or adjusting down gradually over time, etc. Thanks!
ok It's fake, on the first foto's there is hair on the breast, on the second picture there's no hair anymore, the hair wil cover the muscle so you don't see it.
And, the lighting has much effect, i know that i am speaking dutch englisch, butt i trying to warn you
I need these tips in simple language to understand faster
This is incredible, I read the Colorado experiment with Mr Jones & love the science behind it! Question though- what was the calorie intake like on a daily basis?
Impressive Tim. I remember reading this in 4hbody, at the time I was experimenting with the slow carb diet. Do you think this will have a similar effect to build muscle mass for a female a well? I would also like to lose a little more body fat as my abs are finally starting to show. I lift heavy 5-6 days/week and am somewhere between 18-20% bodyfat. I have hit a plateau with both muscle gain and fat loss. if I could kill two birds with one stone that would be great. I'm also just wondering how feasible it is for a female to gain a lot of muscle mass in such a short amount of time. We have a much harder time putting on muscle mass than men. It has taken me a couple of years to gain the muscle I have now. I also must say that to cut down to working out twice per week would take a HUGE leap of faith for someone that works out regularly. It's intriguing!
Just started up, but I'm modifying this for my age group (64) and doing 4 days in a row, Mon. upper, Tues. lower, Wed. upper, Thurs. lower, then nothing til' the next Monday. That way both upper and lower get hammered (my version of hammered, 3 heavy sets on all muscle groups, but careful on the joints) every other day, then each gets a full 5 days rest…will keep ya 'posted'.
As a follower of the slowcarb diet and as someone who is interested in pursuing Geek to Freak, how many grams of protein per kg of body weight would you suggest, and if its already in your book could you suggest a page number?
34 lbs of muscle in 4 weeks? Not only far fetched, it's literally impossible, even on steroids
awesome content. thanks for the information.
Sunestron is the best way to gain muscles fast i also brought this for my husband and he was really excited about this when I told him about it, and is loving the results so far. He's been working out and pushing harder at the gym, and he's already seeing a difference in his lean muscle mass. His arms are becoming bigger and more muscular. He's a happy man, and he looks even better than usual!
Does anyone know his daily exercise routine in achieving these results? Maybe I just missed it
Does anyone know what workout routine he used?
This would have more credibility if poses, wardrobe and effort were obviously staged for the illusion effect. Pity. Everyone wants so desperately to believe and deceptors prey on that desperation.
"exercise your entire body each workout to elicit a maximal hormonal (testosterone, growth hormone + IGF-1) response." Dose it matter if its before or after whatever workout you are doing?
Hi, where can I find information on diet on the geek to Greek training program. I brought the 4hour working week and the 4 hour body. Both life changing books if you take the advise. Great books. Thanks Sean
Beastly bulk with less fur! Not sure about advice for ladies, you guys assume that our bodies react the same way. In fact, depending on lifecycle age, we react much differently.
I love Tim and have watched many of his videos and learned quite a bit — but as someone who has been lifting for a long time, I can tell you it's not humanly possible to add 34 pounds of muscle in 4 weeks…or maybe even 4 years.
34 lbs of muscle in 4 weeks? Riiiiight.
Hi. I read the Colorado experiment. I've read 4-hour body. I'm female desiring to drop body fat and increase muscle. How would you adapt this to p90x? A 5/5 cadence? Do total body workout 2 times a week? What would be a good total body workout? Thanks.
In argumentation theory, an argumentum ad populum (Latin for "appeal to the people") is a fallacious argument that concludes that a proposition is true because many or most people believe it: "If many believe so, it is so." This type of argument is known by several names,[1] including appeal to the masses, appeal to belief, appeal to the majority, appeal to democracy, appeal to popularity, argument by consensus, consensus fallacy, authority of the many, and bandwagon fallacy (also known as a vox populi),[2] and in Latin as argumentum ad numerum ("appeal to the number"), and consensus gentium ("agreement of the clans"). It is also the basis of a number of social phenomena, including communal reinforcement and the bandwagon effect. The Chinese proverb "three men make a tiger" concerns the same idea. Just because you disagree or think its impossible doesn't make it so. Its unpopular opinion being reinforced. Hence denial and anger, which is the first stage of acceptance. I went from 168 lbs to 185 lbs in 30 days. And I did it half heatedly I changed the cadence of my reps to 5-5 and ate like a horse including the supplement stack of Alphalipoic acid and other supplements mentioned in the 4 hour body. Got good sleep and timed my workouts well. It was solid muscle gain as my BF % stayed the same. YOU HAVE TO DO THE FUCKING WORK. AND EAT.
can this work with cals?
Are you guys here just to doubt him? Sheesh. Give a guy a break.
What kind of adverse effects would running 3-4 times per week while training for a marathon have on this strategy?
Tim, I'd like to see a comparative experiment with an ectomorph vs Endomorph.
would like to know what is a slow carb diet
Should I combine the geek to freak exercises with the Kiwi's perfect bum A and B workouts totaling 4 workouts a week or do I just stick to one? This is for an 8-week bikini body (NPC competition).
I need to borrow you for a month! I get off work at 4:30. Meet me at the gym at 4:31 (That's where I am employed👍) [Moderator: Street address removed] Tyndall AFB, FL 32403 Tomorrow would be fine👍
I like the "before" photos better. 🙂
The moment I read, "4 hours a week," my jaw dropped. You can count on this "lass" taking your advice. Kudos, by the way!
Timi, I love you, your podcast, ur tv show and your books, but to gain 34 lbs in a month with 4 hours of training is just not true. Im trying to understand how to not think this is just big BS but I really need help with this. Nobody who has ever been to a gym, much less people who works out for life could possibly believe this. I think your credibility is tremendously important, especially for those of us who follow you and read your material and buy your books.
When you took your supplements, listed under "How did I do it" in the Geek to Freak chapter, were you only taking the supplements on workout days, or daily even on rest days?
Amazing article and also great suggestions about muscles growth. It may be true that should you want to increase muscle expansion, you need a mix of healthy ingesting, supplements, and also a training program designed specifically for build muscle size. Thanks for discussing valuable information regarding muscle growing.
Can you explain how the waist increases almost 4" wile the body fat decreases nearly 4%?
When doing the workout I'm blacking out / getting migraines during the incline bench on the slow reps. Anyone else have this problem?
Can you confirm you didn't get a little Deca in there? Be honest dude.
Hello Tim! After reading the 4 hour body book, I wanted to ask if you have two exercises that you believe are very effective for forearm growth? Thank you!
Impressive Tim. How tall are you?
Hey Tim, Firstly, thanks for writing all your books, you've had a more significant effect on my life than you could possibly imagine. I've been slow carbing past few months and I've lost 25lbs so far as a vegetarian, which is clutch!! About to start the geek to freak protocol but I recently came accross Dr.T Collin Campbell's study linking casein to cancer. Is Casein required? Can I substitue this with whey protein isolate? Also not certain you still respond to this thread (last response was 2014) :p Thanks for your advice and time 🙂
Is there a template or plan to get an idea of the schedule or example of a day at the gym?
Very nice transformation Tim.
common man , i do respect you a lot , but you know that gaining 34 lbs. of Muscle in 4 Weeks is not possible ( even with steroids ) ? ps : i didn't read the article.
Hey Tim, Just wondering what your maintenance looked like after finishing the protocol? Was it fairly easily maintained? Also, prior to doing the protocol what did you training look like? Lastly, what was your training age when started doing this? In the name of being scientific, I’m just wondering if any of those variables created a bit of a sling shot for your results. Very impressive either way!
Hi Tim, over the years I think i bought almost all of your books of different topics, now, after having trained myself to a flat stomach I stumbled across this online post and read the chapters in the book. From your other books I know your stuff works and I'm the guy who usually reads and tries without asking but one thing I'd like to have confirmed that i have understood it correctly before risking to lose my hard work invested so far 😉 So, if i (160lbs) eat 5000 cals of macaroni and tuna for a month with 2×30 minutes of training a week without any extra training/cardio, i will not get fat and maybe even lose some more fat? Usually I would not believe that but if you say so i'll give it a shot, cause i know your other stuff worked as well. Thanks!
What are the common mistakes people make while following occam's protocol?
Hello Tim and other readers, First off, I have red the 4-hour body and I just started the slow carb diet to life a healthier life. I am 24 years old and weight only 132 pounds. I would't mind gaining some weight, eighter muscle or fat. So my questions is; Does the rule of not eating white carbs only apply when you want to lose weight? Or are there other benefits to not eating them Because there's this 'myth' that you need to gain weight with carbs in order to start gaining muscle. Thanks for the response(s) in advance. Peter.
Hey Tim. I’m a week into my weight gaining program and it’s unfortunate that I couldn’t have timed it any better. The gyms are closed and I’m left with no equipment and no motivation. Any tips or tricks on how I can still put on without the use of gym equipment?
Can anyone explain, in rule 4 what is "protein uptake downregulation."?
Great stuff Tim. But I have a quick question. What is the best oil to cook with? is it coconut oil?
Hey Tim, I guess that this is because this post is old, but I think the way that you instantly related weight loss with women was a bit fucked up. I know plenty of girls that are trying to gain some weight and others that are brainwashed into thinking that they should be as thin as possible when they are already completely fine.
how much anadrol did you take??
Hello, I am doing Geek to Freak right now, and I would like to add milk to my diet. Can anyone tell me if non-organic milk (whole or 2%) is a good option or should it be avoided? Thanks.
Impossible to gain 34 pounds of muscle in one month even with anabolic steroids. Just complete lies. There may be some good stuff in your recommendations but my goodness don't lie to people, just wow.
Thankyou so much for inspiring so much from just one post. It really helped me to boost my confidence level
Oh yeah 34 pounds of muscle after 4 hours of working out. Where do I put in my bank account number?
100% bullshit. Diet is a huge factor in muscle growth but it is laughable to believe he gained 34 lbs of muscle in a month. I don’t think people realize how much 34 lbs of muscle is and he’s only around 150-160 lbs to start, from his photos he’s gained maybe 5-8 lbs of muscle and uses stance/positioning tricks to try to achieve a more drastic look. His body positioning differs in the Before and After photos, he doesn’t curl his arms or arch his back in the original photos. He only does so in the After photos to appear more muscular, you can do the same by trying this out in a mirror. It’s also physically impossible to gain 34 lbs of muscle this quickly, even if you were on steroids!! You gain muscle mass when your body repairs the muscle fibers damaged from working out, a process that must be repeated over and over to achieve sizable gains. A month wouldn’t be enough time to gain 34 lbs in muscle even if you were working out 5 days a week, yet we are supposed to believe it was achieved in 4 hours total?? Not a chance, anyone who says different is ignoring basic human anatomy. A few people mentioned the author isn’t selling anything but if you read the footnotes he authored “The 4- Hour Body” and “The 4-Hour Workweek”, both of which are targeting people who want success without putting in the necessary work. There is a reason that athletes training in the off-season or actors working out for a role spend so much time in the gym with a focus on nutrition— the only thing that ensures success is hard work. Look at the other photos of the author in the “related posts”, he is not muscular. If you believe his claims, you are not a rational adult.
What an enchanting idiot. His statements differ by about 10 times from the maximum physiologically possible. Scam
Nice photos. Very inspiring. Good influence.
Wow, Tim you used to have hair.
I fallowed his protocol loosely for a month I worked out 3 to ,4 times a week down 9 pounds definitely gained strength 64 years old

Dude, it works… Ive had success doing it as have thousands of others. Take a look at this post for further proof… http://fourhourworkweek.com/2013/05/11/how-to-gain-20-pounds-in-28-days-the-extreme-muscle-building-secrets-of-ufc-fighters/
It's about time people caught on to this phony baloney and it's "I'm more qualified "than" all of you, not "then." The guy is a fake in every way – blowhard. but he made a lot of money as a consummate bullshitter.
Why not?
Oh, geez. They must have realized the traffic I was sending and changed the site. Sorry about that. I'll change the link now. Ugh.
Gotcha covered– give me a month and I'll come back to link my own attempt at a post.
Hey Victor, As someone who has 10+ years lifting and most of those being at 200+ I can agree and sympathize with the skepticism towards this thought process. I can neither speak for or against his results, but anytime I find something hard to believe I try to prove/disprove it. I started this routine this week, first workout today actually. The muscle depletion and fatigue is very real, and I have experienced a ravenous hunger all day since. So higher metabolism is absolutely a result, jury is still out on the gainz. An interesting read on the mentioned "Colorado Experiment" is "Colorado Experiment: Fact or Fiction" by T-Nation a strength and fitness site. Happy learnings. -Zak
Hi, this sounds encouraging. How many cals did you eat daily? 2×30 a week and no further training? I know your post is old but I'd really appreciate a reply. Thanks
Thank you for the above breakdown… Let's just say 34 lbs of muscle not total body weight but pure muscle was possible…you wouldn't want to do it anyway because your tendons would fucking snap like old rubber bands.
