Walter WhinneryI 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.

r 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!

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.

Hi Ravi,
I actually train alone and have since age 15. I prefer training between 8-10pm and use a “power rack” (a stand-alone cage that acts as a spotter) for safety. Generally, I favor machines over free-weights for ease-of-use, with the exception of deadlifts for experienced trainees. Resistance is resistance, and machines require less clean up.
I’ve put friends — even vegetarians — on this program, who have gained 10-20 lbs. in four weeks despite consuming insufficient calories. For ambitious eaters, and eating is the hardest part, that number will be much higher.
Weight training for me is “me time” and almost meditative, so I never train with a partner. It’s therapeutic to count the cadence (5 seconds up, 5 seconds down) and forget the world for 20-30 minutes at a time.
Last but not least, you are right: short and intense are the defining features of this workout. That said, there is one additional element more neglected than any other: massive recovery time.
Cheers!
Tim

1. Yes, it is 4 hours and not 8 hours! I had 8 workouts per month in my head (which is accurate), and screwed up the arithmetic. Guess I won’t be writing “The 4-Hour Mathematician” anytime soon ;)
2. I did not maintain the gains. Why? Too much eating. I estimate (I don’t both counting) that I was consuming between 5,000-8,000 calories per day in 5 or 6 divided meals, which is a full-time job. I spent more time eating than working out! I much prefer to be around 165 lbs. for athletics.
3. For each set, I target to reach failure after 80-120 seconds, thus 8-12 repetitions at 5/5 cadence. This is sometimes referred to as “time under tension” (TUT). I will usually do one marathon workout of 2-3 hours before beginning the program to determine an appropriate starting weight for each exercise.
4. Doing bicep curls WILL cause your skin to darken and your body hair to fall out. Since I didn’t do bicep curls, I had to use Nair and go to a tanning salon ;)
Holy crap — I just got some HUGE NEWS via cell phone from my publisher. No joke… you’ll hear about it in the next few days. In the meantime, please check out the writings of a few of my favorites (sorry about Jones’ stuff coming off like a Nautilus ad, as good as his machines are):

Hi David!
Please search my name on http://www.bodybuilding.com — there is a more complete explanation of my workout and diet there.
Good luck and keep us all posted on progress — don’t forget to take before-after photos :)

1. I am a trainee who is used to multiple sets at a high weight, with low reps (3-6). Since your program calls for a 5/5 cadence, should I be expecting to use a weight around 50% of my 1RM? I’m going to suspend my disbelief for the duration of this program, so I just want to know what to expect.
TTT: That sounds about right. Your current regimen is great for relative strength, assuming long rest intervals, but this is designed with maximizing muscle nutrient density and hypertrophy. Start with 50% and then work up or down as needed. I suggest one 1-2-hour workout of testing just to determine the proper weight for exercises.
2. Here are the exercises I was considering performing: squats, dips, chinups, military presses, one arm dumbbell rows. What do you think of that? Do you have any recommendations to make in this regard, or are these exercises just fine?
TTT: These are just fine. You’re hitting all the primary movers.
3. For a few exercises, it seems like the grip would give out before the target muscle (for example, chinups, and one arm dumbbell rows), since a set would last 80-120 seconds. How can I work around that?
TTT: The weight will be less, but you can: 1) use a phosphate buffering supplement to decrease lactic acid build-up, and/or 2) use lifting wraps. I discourage #2 unless absolutely necessary.
Good luck and happy gaining!

Hi Tim!
First, I loved your book! That was what led me here to your blog..In this post you said not to exceed 2 exercises per week,yet in your article on bodybuilding.com, you said to exercise every other day (” PUSH, one day off, PULL, one day off, LEGS, one day off,”). Does that mean for the for the first week of the 28 days, you need to exercise more frequently? I am a bit confused.
Thanks!

Hi Dan,
This is generally true. You do sessions less frequently as you get stronger to allow for recovery.
Good luck!

Hi there, man.
I just listened to the audiobook and then read a lot of the blog, and then just watched your whole interview with google (I wonder how many people actually watch a 72min interview, but… i did). I’m a Brazilian entrepeneur and intend to work around the globe doing crazy stuff like you did veeery soon.
About this post: I liked a lot the system you used, and have read the Colorado Experiment article as well. Some people habve asked, and though you did respond to some criticism (giving a lot of attention for somebody like him) you still didn’t asnwer to people’s most asked questions, here’s one I’ve also had the curiosity too, so I’m re-asking:
Question> I got how you do the repetitions (5/5 until failure) but how do you exactly calculate the maximum wheight is still an unanswered doubt.

Hi Luis (and all),
Sorry for the delay, but I write on this blog when I have the enthusiasm and time. To your topic…
Good question. Here’s the simple answer: I generally spend about 2 hours with a trainee before any real workouts and have them do 10-rep sets of increasing weight with a 2-sec up and 2-sec down speed for each exercise. Complete one exercise at a time. Take 2 min between sets and exercises. Once the trainee completes a set that would have failed in 2 reps or so, cut 25% off that weight and use it for your next workout at the 5/5 to failure. From there, adjust as needed.
Hope that helps!
Tim

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.

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:
