#1 NEW YORK TIMES BESTSELLER • The game-changing author of The 4-Hour Workweek teaches you how to reach your peak physical potential with minimum effort.

“A practical crash course in how to reinvent yourself.”—Kevin Kelly, Wired

Is it possible to reach your genetic potential in 6 months? Sleep 2 hours per day and perform better than on 8 hours? Lose more fat than a marathoner by bingeing? Indeed, and much more. 

The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body using data science. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation. From Olympic training centers to black-market laboratories, from Silicon Valley to South Africa, Tim Ferriss fixated on one life-changing question: 

For all things physical, what are the tiniest changes that produce the biggest results?

Thousands of tests later, this book contains the answers for both men and women. It’s the wisdom Tim used to gain 34 pounds of muscle in 28 days, without steroids, and in four hours of
total gym time. From the gym to the bedroom, it’s all here, and it all works. 

You will learn (in less than 30 minutes each):

• How to lose those last 5-10 pounds (or 100+ pounds) with odd combinations of food and safe chemical cocktails
• How to prevent fat gain while bingeing over the weekend or the holidays
• How to sleep 2 hours per day and feel fully rested 
• How to produce 15-minute female orgasms 
• How to triple testosterone and double sperm count
• How to go from running 5 kilometers to 50 kilometers in 12 weeks 
• How to reverse “permanent” injuries  
• How to pay for a beach vacation with one hospital visit

And that's just the tip of the iceberg. There are more than 50 topics covered, all with real-world experiments, many including more than 200 test subjects. You don't need better genetics or more exercise. You need immediate results that compel you to continue.

That’s exactly what The 4-Hour Body delivers.

THE MINIMUM EFFECTIVE DOSE

From Microwaves to Fat-Loss

Arthur Jones was a precocious young child and particularly fond of crocodiles.

He read his father's entire medical library before he was 12. The home environment might have had something to do with it, seeing as his parents, grandfather, great-grandfather, half-brother, and half-sister were all doctors.

From humble beginnings in Oklahoma, he would mature into one of the most influential figures in the exercise science world. He would also become, in the words of more than a few, a particularly "angry genius."

One of Jones's protégés, Ellington Darden PhD, shares a prototypical Jones anecdote:

In 1970, Arthur invited Arnold [Schwarzenegger] and Franco Colombu to visit him in Lake Helen, Florida, right after the 1970 Mr. Olympia. Arthur picked them up at the airport in his Cadillac, with Arnold in the passenger seat and Franco in the back. There are probably 12 stoplights in between the airport and the Interstate, so it was a lot of stop-and-go driving.

Now, you have to know that Arthur was a man who talked loud and dominated every conversation. But he couldn't get Arnold to shut up. He was just blabbing in his German or whatever and Arthur was having a hard time understanding what he was saying. So Arthur was getting annoyed and told him to quiet down, but Arnold just kept talking and talking.

By the time they got onto the Interstate, Arthur had had enough. So he pulled over to the side of the road, got out, walked around, opened Arnold's door, grabbed him by the shirt collar, yanked him out, and said something to the effect of, "Listen here, you son of a bitch. If you don't shut the hell up, a man twice your age is going to whip your ass right out here in front of I-4 traffic. Just dare me."

Within five seconds Arnold had apologized, got back in the car, and was a perfect gentlemen for the next three or four days.

Jones was more frequently pissed off than anything else.

He was infuriated by what he considered stupidity in every corner of the exercise science world, and he channeled this anger into defying the odds. This included putting 63.21 pounds on champion bodybuilder Casey Viator in 28 days and putting himself on the Forbes 400 list by founding and selling exercise equipment manufacturer Nautilus, which was estimated to have grossed $300 million per year at its zenith.

He had no patience for fuzzy thinking in fields that depended on scientific clarity. In response to researchers who drew conclusions about muscular function using electromyography (EMG), Arthur attached their machines to a cadaver and moved its limbs to record similar "activity." Internal friction, that is.

Jones lamented his fleeting time: "My age being what it is, universal acceptance of what we are now doing may not come within my lifetime; but it will come, because what we are doing is clearly established by simple laws of basic physics that cannot be denied forever." He passed away on August 28, 2007, of natural causes, 80 years old and as ornery as ever.

Jones left a number of important legacies, one of which will be the cornerstone of everything we'll discuss: the minimum effective dose.



The Minimum Effective Dose

The minimum effective dose (MED) is defined simply: the smallest dose that will produce a desired outcome.

Jones referred to this critical point as the "minimum effective load," as he was concerned exclusively with weight-bearing exercise, but we will look at precise "dosing" of both exercise and anything you ingest.1

Anything beyond the MED is wasteful.

To boil water, the MED is 212°F (100°C) at standard air pressure. Boiled is boiled. Higher temperatures will not make it "more boiled." Higher temperatures just consume more resources that could be used for something else more productive.

If you need 15 minutes in the sun to trigger a melanin response, 15 minutes is your MED for tanning. More than 15 minutes is redundant and will just result in burning and a forced break from the beach. During this forced break from the beach, let's assume one week, someone else who heeded his natural 15-minute MED will be able to fit in four more tanning sessions. He is four shades darker, whereas you have returned to your pale pre-beach self. Sad little manatee. In biological systems, exceeding your MED can freeze progress for weeks, even months.

In the context of body redesign, there are two fundamental MEDs to keep in mind:

To remove stored fat -- do the least necessary to trigger a fat-loss cascade of specific hormones.

To add muscle in small or large quantities -- do the least necessary to trigger local (specific muscles) and systemic (hormonal 2) growth mechanisms.

Knocking over the dominos that trigger both of these events takes surprisingly little. Don't complicate them.

For a given muscle group like the shoulders, activating the local growth mechanism might require just 80 seconds of tension using 50 pounds once every seven days, for example. That stimulus, just like the 212°F for boiling water, is enough to trigger certain prostaglandins, transcription factors, and all manner of complicated biological reactions. What are "transcription factors"? You don't need to know. In fact, you don't need to understand any of the biology, just as you don't need to understand radiation to use a microwave oven. Press a few buttons in the right order and you're done.

In our context: 80 seconds as a target is all you need to understand. That is the button.

If, instead of 80 seconds, you mimic a glossy magazine routine--say, an arbitrary 5 sets of 10 repetitions--it is the muscular equivalent of sitting in the sun for an hour with a 15-minute MED. Not only is this wasteful, it is a predictable path for preventing and even reversing gains. The organs and glands that help repair damaged tissue have more limitations than your enthusiasm. The kidneys, as one example, can clear the blood of a finite maximum waste concentration each day (approximately 450 mmol, or millimoles per liter). If you do a marathon three-hour workout and make your bloodstream look like an LA traffic jam, you stand the real chance of hitting a biochemical bottleneck.

Again: the good news is that you don't need to know anything about your kidneys to use this information. All you need to know is:

80 seconds is the dose prescription.

More is not better. Indeed, your greatest challenge will be resisting the temptation to do more.

The MED not only delivers the most dramatic results, but it does so in the least time possible. Jones's words should echo in your head: "REMEMBER: it is impossible to evaluate, or even understand, anything that you cannot measure."

80 secs. of 20 lbs. 10:00 mins. of 54°F water 200 mg of allicin extract before bed

These are the types of prescriptions you should seek, and these are the types of prescriptions I will offer.



RULES THAT CHANGE THE RULES

Everything Popular Is Wrong

This is clearly a lie. Gaining 34 lb in 28 days requires a caloric surplus of 4300 calories per day, so for a guy his size, he must have eaten 7000 calories a day. He expects me to believe that he dropped 4% in bodyfat as a result of eating 7000 calories? . . ."

I took a big swig of Malbec and read the blog comment again. Ah, the Internet. How far we haven't come.

It was amusing, and one of hundreds of similar comments on this particular blog post, but the fact remained: I had gained 34 pounds of muscle, lost 4 pounds of fat, and decreased my total cholesterol from 222 to 147, all in 28 days, without anabolics or statins like Lipitor.

The entire experiment had been recorded by Dr. Peggy Plato, director of the Sport and Fitness Evaluation Program at San Jose State University, who used hydrostatic weighing tanks, medical scales, and a tape measure to track everything from waist circumference to bodyfat percentage. My total time in the gym over four weeks?

Four hours.3 Eight 30-minute workouts.

The data didn't lie.

But isn't weight loss or gain as simple as calories in and calories out?

It's attractive in its simplicity, yes, but so is cold fusion. It doesn't work quite as advertised.

German poet Johann Wolfgang Goethe had the right perspective: "Mysteries are not necessarily miracles." To do the impossible (sail around the world, break the four-minute mile, reach the moon), you need to ignore the popular.

Charles Munger, right-hand adviser to Warren Buffett, the richest man on the planet, is known for his unparalleled clear thinking and near-failure-proof track record. How did he refine his thinking to help build a $3 trillion business in Berkshire Hathaway?

The answer is "mental models," or analytical rules-of-thumb4 pulled from disciplines outside of investing, ranging from physics to evolutionary biology.

Eighty to 90 models have helped Charles Munger develop, in Warren Buffett's words, "the best 30-second mind in the world. He goes from A to Z in one move. He sees the essence of everything before you even finish the sentence."

Charles Munger likes to quote Charles Darwin:

Even people who aren't geniuses can outthink the rest of mankind if they develop certain thinking habits.

In the 4HB, the following mental models, pulled from a variety of disciplines, are what will separate your results from the rest of mankind.



New Rules for Rapid Redesign

NO EXERCISE BURNS MANY CALORIES.

Did you eat half an Oreo cookie? No problem. If you're a 220-pound male, you just need to climb 27 flights of stairs to burn it off.

F*cking hell, right? It's enough to make a lumberjack cry. Confused and angry? You should be.

As usual, the focus is on the least important piece of the puzzle.

But why do scientists harp on the calorie? Simple. It's cheap to estimate, and it is a popular variable for publication in journals. This, dear friends, is referred to as "parking lot" science, so-called after a joke about a poor drunk man who loses his keys during a night on the town.

His friends find him on his hands and knees looking for his keys under a streetlight, even though he knows he lost them somewhere else. "Why are you looking for your keys under the streetlight?" they ask. He responds confidently, "Because there's more light over here. I can see better."

For the researcher seeking tenure, grant money, or lucrative corporate consulting contracts, the maxim "publish or perish" applies. If you need to include 100 or 1,000 test subjects and can only afford to measure a few simple things, you need to paint those measurements as tremendously important.

Alas, mentally on your hands and knees is no way to spend life, nor is chafing your ass on a stationary bike.

Instead of focusing on calories-out as exercise-dependent, we will look at two underexploited paths: heat and hormones.

So relax. You'll be able to eat as much as you want, and then some. New exhaust pipes will solve the problem.



A DRUG IS A DRUG IS A DRUG

Calling something a "drug," a "dietary supplement," "over-the-counter," or a "nutriceutical" is a legal distinction, not a biochemical one.

None of these labels mean that something is safe or effective. Legal herbs can kill you just as dead as illegal narcotics. Supplements, often unpatentable molecules and therefore unappealing for drug development, can decrease cholesterol from 222 to 147 in four weeks, as I have done, or they can be inert and do absolutely nothing.

Think "all-natural" is safer than synthetic? Split peas are all-natural, but so is arsenic. Human growth hormone (HGH) can be extracted from the brains of all-natural cadavers, but unfortunately it often brings Creutzfeldt-Jakob disease with it, which is why HGH is now manufactured using recombinant DNA.

Besides whole foods (which we'll treat separately as "food"), anything you put in your mouth or your bloodstream that has an effect--whether it's a cream, injection, pill, or powder--is a drug. Treat them all as such. Don't distract yourself with labels that are meaningless to us.



THE 20-POUND RECOMP GOAL

For the vast majority of you reading this book who weigh more than 120 pounds, 20 pounds of recomposition (which I'll define below) will make you look and feel like a new person, so I suggest this as a goal. If you weigh less than 120 pounds, aim for 10 pounds; otherwise, 20 pounds is your new, specific goal.

Even if you have 100+ pounds to lose, start with 20.

On a 1-10 attractiveness scale, 20 pounds appears to be the critical threshold for going from a 6 to a 9 or 10, at least as tested with male perception of females.

The term "recomposition" is important. It does not mean a 20-pound reduction in weight. It's a 20-pound change in appearance. A 20-pound "recomp" could entail losing 20 pounds of fat or gaining 20 pounds of muscle, but it most often involves losing 15 pounds of fat and gaining 5 pounds of muscle, or some blend in between.

Designing the best physique includes both subtraction and addition.



THE 100-UNIT SLIDER: DIET, EXERCISE, AND DRUGS

How, then, do we get to 20 pounds?

Imagine a ruler with 100 lines on it, representing 100 total units, and two sliders. This allows us to split the 100 units into three areas that total 100. These three areas represent diet, exercise, and drugs.

An equal split would look like this:

________/________/________ (33% diet, 33% drugs, 33% exercise)

It is possible to reach your 20-pound recomp goal with any combination of the three, but some combinations are better than others. One hundred percent drugs can get you there, for example, but it will produce the most long term side effects. One hundred percent exercise can get you there, but if injuries or circumstances interfere, the return to baseline is fast.

/__________/ (100% drugs) = side effects

//__________ (100% exercise) = easy to derail

Here is the ratio of most of the fat-loss case studies in this book:

______/_/___ (60% diet, 10% drugs, 30% exercise)

If you're unable to follow a prescribed diet, as is sometimes the case with travel or vegetarianism, you'll need to move the sliders to increase the % attention paid to exercise and drugs. For example:

_/____/_____ (10% diet, 45% drugs, 45% exercise)

The numbers need not be measured, but this concept is critical to keep in mind as the world interferes with plans. Learning diet and exercise principles is priority #1, as these are the bedrock elements. Relying too much on drugs makes your liver and kidneys unhappy.

The percentages will also depend on your personal preferences and "adherence," which we cover next.



1. Credit is due to Dr. Doug McGuff, who's written extensively on this and who will reappear later.

2. In fancier and more accurate terms, neuroendocrine.

3. In this case, the "4-Hour Body" is quite literal.

4. These "mental models" are often referred to as heuristics or analytical frameworks.

Just beginning to read but find it interesting on page 15, there are two references to other areas of the book.“There are dozens of tests mentioned throughout this book. If you ever ask yourself "How do I get that tested?" or wonder where to start, the "Getting Tested" list on page 478 is your step-by-step guide.”The list is actually on 472“ Not sure how much a gram is, or what the hell 4 ounces is? Just flip to the common measurements on page 476 and unleash your inner Julia Child.”Actually on page 470.The contents have both listed correct. - no big deal but considering the cost the editors should have discovered this.Maybe a pet peeve - doesn’t change the value of the information.

WEIGHT LOSS SECTION

Last summer I lost 18 pounds, getting down to 6% body fat. This enabled me to finish 29th in the Pikes Peak Ascent, which climbs nearly 8000 feet in 13.5 miles and was the 7th Annual World Mountain Running Association (WMRA) Long Distance Challenge. I received the award for 1st place in the 45-49 age group.

Ferriss advocates keeping your blood sugar even, i.e., avoiding spikes and drops by eating low on the glycemic index. I've done this for nearly 25 years and I believe it's the most important dietary advice. Ferriss should have mentioned that Barry Sears' Zone Diet books go into more detail on low-glycemic eating; there are more health benefits besides losing weight. Sears' website also sells products that help with this diet, e.g., high-protein, low-glycemic index pasta. Ferriss recommends lemon juice or cinnamon to lower the glycemic index of foods, something I'd never heard of. He could have mentioned that Celestial Seasonings makes a cinnamon tea, called GingerBread Spice, that you can drink with a meal instead of putting cinnamon in foods.

Even though I've eaten low-glycemic foods for nearly 25 years my weight had crept up a little each year. Last summer I tightened up my diet but lost only 3 pounds in 7 weeks. I then discovered a technique that Ferriss doesn't mention: "Eat breakfast like a king, lunch like a queen, and supper like a pauper." A thin French friend told me this is how Europeans stay thin. I ate big breakfasts with protein (fish, lean meat, eggs, etc.), protein shakes with spirulina around noon, big lunches around 3pm, and then just a green salad or fruit salad in the evening, enough to not go to bed hungry. I then lost 15 pounds in 12 weeks.

Ferriss has good advice for eating low on the glycemic index: not eating white sugar, white flour, and other refined carbohydrates; and not drinking calories, e.g., fruit juice packs a lot of sugar. He also says to eat the same few meals over and over. This makes staying on your diet easy.

Ferriss recommends not eating fruit, because fructose converts to glycerol phosphate that facilitates fat storage. I'm skeptical of this, because fruits are more than just fructose, e.g., they have fiber. Just because a reaction occurs in vitro (in a test tube) doesn't mean the same thing will happen in vivo (in a living person). Given his huge fan base maybe he could ask a few hundred of his blog readers to divide into two groups, one of which eats fruit and the other doesn't, and see who loses more weight. I'll bet the non-fruit eaters will substitute another sweet that is more fattening and lose less weight.

Ferriss recommends taking one day off a week from your diet and eating anything (and everything) you want. He says that this "binge" day will support weight loss by keeping your metabolism high. Again, I'm skeptical and I'd like to see a clinical trial. However, last summer I did a "binge day" every week without realizing it. I had a race every week and after each race ate whatever I wanted the rest of the day.

Ferriss recommends not eating dairy, as it has a high insulinemic response despite its low glycemic index.

When Ferriss advocated a high-protein diet, recommending that I eat almost 200 grams of protein per day, my first reaction was "What about the China Study?" This book, by Colin and Thomas Campbell, correlated animal-based diets with cancer, and recommended eating a plant-based (vegan) diet. Ferriss's website has a link to Christopher Masterjohn's critique of "The China Study." Colin Campbell's study with rats fed aflatoxin (one of the most potent carcinogens) found that a diet with 20% casein (one of the proteins in milk) led to every rat developing cancer, when none of the rats whose diet was 5% casein developed cancer. Apparently casein signals your cells to grow, which is good if you're a baby but not good if you have cancer. Masterjohn then shows how the Campbells extrapolated this one study to say that all milk proteins facilitate cancer growth, when whey (another milk protein) doesn't facilitate cancer growth, and to say that all animal protein facilitates cancer growth (also not true).

Ferris says that canned and frozen foods are just as good as fresh. I agree with him regarding canned beans, but I believe that fresh fruits and vegetables are necessary for my health. Ferriss correctly points out that my grandmother, born in Poland in 1904, ate one orange each year, on Christmas. But my grandmother was tiny compared my cousins and myself. One of the clerks at the natural foods supermarket near my house is 25 and was diagnosed with cancer, diabetes, and heart disease. He switched to a raw foods diet and all of his health problems disappeared. He told me that previously he ate a "standard American diet," i.e., packaged processed foods. I've always eaten big salads, both green salads and fruit salads. If I don't eat raw foods, e.g., when traveling, after a couple days I crave raw foods. I don't know whether raw foods diets work due to something in raw foods, e.g., enzymes that are destroyed by heat, or if these diets work because of what's not in them, e.g., packaged processed foods. Ferriss recommends eating slowly, and raw foods take time to eat. When I make a big salad for breakfast with greens, beans, and smoked salmon it takes me all morning to finish it.

Ferriss doesn't mention spirulina. I put two tablespoons in my mid-day protein shake. Spirulina is arguably the perfect food, if you can handle the swamp taste. It's high in protein, with balanced amino acids; includes essential fatty acids; vitamins, especially the B vitamins lacking in vegetarian diets; minerals; and photosynthetic pigments, i.e., it's really green.

Ferriss suggests cold exposure (cold showers or ice baths) to lose weight, gain muscle, treat insomnia, boost immunity, treat depression, and increase testosterone and sperm count. Dathan Ritzenhein used a cryosuana, exposed to -275 degree nitrogen vapors for 2.5 minutes, the day before the New York Marathon, where he finished 8th in 2:12. At first I was skeptical of Ferris's claim that cold exposure aids weight loss because I keep the house cold all winter and exercise outside 2+ hours a day, often in sub-zero temperatures, and I gain weight every winter. Then I realized that Ferriss is right. Cold exposure makes me crave peanut butter sandwiches and other high fat, calorie-dense foods. In the summer I resist cravings relatively easily but in the winter the cravings are more powerful. I'm sure that if I resisted cravings brought on by cold exposure I'd lose weight fast.

I like this book because it's a collection of new ideas that Ferriss personally tried. 25 years ago I felt like Diogenes with his lamp, except instead of looking for an honest man I was looking for new ideas. In the 1980s new ideas were few and far between. Now with the Internet I feel blessed to live in an age in which new ideas circulate rapidly. Typically each new idea has a single advocate so it's hard to compare whether this idea is better than that idea, unless you take the time (and expense) to try several ideas. Ferriss did just that and is reporting his experiences. In contrast, Andrew Weil writes about the same materials but with an affect of authority, as he's a doctor and reads scientific studies. Ferriss's affect is "I'm a regular guy just like you, I'm not an expert, but I'm intelligent and I can read scientific studies too, and here's what happened when I tried this..." Another reviewer said that Ferriss's book is his new "bible." I don't agree with that. If you want a "bible," read Andrew Weil. If you want interesting ideas and personal experiences, read Ferriss.

ADDING MUSCLE SECTION

I'm not interested in body building so I skimmed this section. However, this section made me realize how different bodybuilders are from outdoor athletes. Or at least how different Ferriss and I are. Later he talks about learning to run and to swim, i.e., these are new skills for him. He doesn't mention cycling or playing team sports. Before reading this section I hadn't realized how many drugs bodybuilders take! (Ferriss suggests googling "Andreas Munzer autopsy".)

Ferriss doesn't include a chapter about integrating exercise into your daily life. E.g., riding a bike to work instead of driving, or joining a mixed-gender softball team to meet singles. I don't like going to gyms, I only exercise when it's fun or there's a purpose.

IMPROVING SEX SECTION

This section starts with how non-orgasmic women can learn to masturbate, e.g., by reading Betty Dodson's book. I watched Dodson's video about ten years ago and one item remains with me clearly: Dodson tells women to schedule three to four hours when they want to masturbate!

Ferriss shows some improved positions for couples. My wife and I tried these and she was unimpressed (but then she's never had problems with orgasms).

The next chapter explains how Ferriss increased his testosterone 2.5 times: vitamins, ice baths, and cholesterol (egg yolks and steaks). I nearly tripled my testosterone (from barely over 300 to just under 900) by taking a contact improv dance class. Three times a week a dozen sweaty young women and I rolled our bodies over and under each other. (Contact improv is like gymnastics except you use your partner instead of vaults and balance beams.) The pheromones in young women's sweat increases men's testosterone. Someday someone will make a fortune collecting young women's sweat and selling it to middle-aged men. There were also young men in the class, whose sweat literally made me weak and nauseous until I showered. Ferriss doesn't say that lifting weights in gyms surrounded by sweaty young men might lower your testosterone.

Ferriss doesn't discuss why you might not want to increase your testosterone. Testosterone causes baldness, and your hair doesn't grow back if you later lower your testosterone. Testosterone doesn't make you faster: gelding race horses are just as fast as stallions. Ferriss says that when his testosterone was high he literally turned women's heads in restaurants. My experience in the dance class was that the young women literally jumped in the laps of the gay men at the start of class. If they couldn't partner with a gay man then they partnered with women. Every class I'd look around when the instructor said to find a partner, and the only available partners were the other two straight men. We'd do the first exercise together half-heartedly and then ask women to partner with us. Testosterone may have made the women avoid us.

Ferriss doesn't mention that women might want to increase their testosterone. I've read that testosterone is the most effective anti-depressant for women. It also increases their libido. Listen to This American Life's podcast #220: a transgender female-to-male talks about what it was like to receive testosterone injections; and a man who had a medical condition that eliminated testosterone in his body, with the result that he achieved a Buddha-like state of desiring nothing. I performed these two characters in a play, my favorite line was from the transgender man: "Testosterone makes life challenging, but it makes you love the challenges."

The next chapter is about declining sperm count. Ferriss suggests getting your sperm frozen before you're 35, which I did. His other advice is to not carry your cellphone in your pocket (I don't). He barely mentions other ideas such as not drinking out of plastic bottles, avoiding soy foods, and wearing loose boxer shorts instead of tighty whities.

OTHER SECTIONS

The next section is about insomnia. He suggests all sorts of gadgets, cold baths, foods, etc. but doesn't suggest cutting out caffeine. Getting back to cold exposure, I support Ferriss's claim that cold exposure aids sleep. In the upper Midwest people say "good sleeping weather" to describe cold nights. I sleep well when I let the house drop below 50 degrees and pile blankets on my bed.

Next is a section on reversing "permanent" injuries. My massage therapist (whose wife is a physical therapist) was impressed with this section, esp. the Egoscue recommendation.

Next is a section on medical tourism (saving money by going to foreign countries for medical treatment).

Next, Ferriss recommends preventing injuries by getting a Functional Movement Screen (FMS) test. FMS measures left-right differences in strength and balance. I'm putting this on my to-do list.

RUNNING SECTION

I'm 48 and this year ran a 5:08 mile, an 18:09 5K, and a 37:48 10K. I qualified for All-American in a 3000-meter race and I win an age group award in most races. I only run about 3 hours a week: two 45-minute track workouts plus a 1.5-hour club run. An exercise physiologist was amazed that I have a VO2-max of 59 and run this fast on 3 hours a week. Then I said that I walk my dog 2 hours a day, plus we hike twice a week, mixing speedwalking, easy jogging, and stopping to pee every 30 feet. The exercise physiologist said that I have the perfect training plan: a base of daily easy exercise with a few short but intense workouts.

Ferriss recommends running with the Pose technique. I've done this for five years and this has been the best thing I've ever done to improve my running, both for increasing speed and minimizing injuries. Ferriss doesn't mention that the same technique has other names, including Chi Running and Evolution Running.

Ferriss' description of the Pose technique is excellent but he only has photos of himself (before and after). His "before" photos are clearly wrong but his "after" photos aren't much better, likely because he just doesn't run fast. (His 24-minute 5K is what we politely call "mid-pack".) He should have included photos of faster runners who do the Pose Technique better.

Ferriss' 12-week workout schedule is good. The main workout is 800-meter repeats, beginning with two the first week and moving up to six in later weeks. Ferriss doesn't explain why this workout is so important. Running workouts (to oversimplify) either train leg speed or cardiovascular (heart and lungs). 800 meters is three minutes for Ferriss. If you run intervals longer than 3 minutes you don't maximize leg speed. If you run less than 3 minutes you don't maximize heart rate. 3-minute repeats are two workouts in one, training both leg speed and cardiovascular. Ferriss should have explained that you run three minutes, not 800 meters, i.e., a slower runner could run 600 meters, when I run 900 meters and a pro might knock off 1200's. Do two of these the first week and gradually build up to five, or six if you're an animal like Ferriss. All should be equal distance, which means that your first interval feels easy and the last interval is maximum effort.

Ferriss' schedule also includes 100-meter and 200-meter leg speed workouts. This is excellent advice for slow runners trying to get faster. Too many joggers run for miles at a slow pace and never get faster. He also did longer 5K and 10K runs to build endurance, and did some hill repeats to build the strength necessary for trail running. He doesn't mention that the 100-meter repeats should be barefoot on grass, to teach you good form.

Ferriss recommends Inov-8 running shoes. I use Nike Frees. He rightly denigrates Newtons and warns against running barefoot (e.g., Vibram Five Fingers), except for strides on grass.

Fueling during long races is an important subject that Ferriss doesn't adequately cover. But I'll give you a tip that'll make your next race faster. Clear your gastrointestinal tract by not eating solid food for at least 12 hours before the race (i.e., drink only juice and energy drinks). Digestion demands up to 40% of your blood so not having anything in your gut at the start line will provide more blood to your muscles.

GETTING STRONGER

Here's where Ferriss presents weightlifting for runners, based on Barry Ross (coach of Olympic gold medalist Allyson Felix). I don't do weightlifting so these ideas were all new to me.

Ferriss gives two reasons why runners should do strength training (weightlifting). First, distance runners have weak sodium-potassium pumps. The sodium-potassium pump is what enables muscles to return to relaxation after contracting. The discoverer of the sodium-potassium pump won the Nobel Prize. Strength training improves the sodium-potassium pump.

Second, greater ground force support (applying force to the ground at landing) is more important than moving your legs faster.

The recommended strength training is in three stages. First, speedwalking 15 minutes three times a week. I do speedwalking because it gives me leg speed without wearing me out. Ferriss says to start with four weeks of speedwalking.

The second stage is weightlifting. Three times per week you do dynamic stretching, then bench presses or push-ups, then deadlifting, in which you lift the weights only to your knees. Ross's athletes deadlift three times their bodyweight! Finish with an exercise called the Torture Twist to strengthen your core muscles.

The third stage is speedwork on the track. The distances are short. Ross's sprinters, who don't compete in distances longer then 400 meters, don't run more than 70 meters in training. No advice is given for distance runners, but Ferriss's other coach telling him to run 800-meter repeats to train for a 50-kilometer race sounds similar to Ross's short interval speedwork.

Ferriss doesn't mention the one type of weightlifting I do, which is essential for avoiding calf injuries when running with the Pose Technique. Some people call these "toe lifts," I call them "heel lifts." Stand barefoot on a stair on your toes. Lower your heels below your toes. Then raise yourself as high as you can. This strengthens your calf muscles. Start with both feet, then go to one foot as you get stronger.

SWIMMING SECTION

Ferriss recommends Total Immersion Swimming. I did Total Immersion Swimming about five years ago and agree with Ferriss. Before, I panicked and tried to swim fast to avoid drowning. I could swim only two lengths of the pool before reaching anaerobic fatigue. Total Immersion Swimming first taught me to float in the water without panicking. Then you learn to paddle around slowly. Then you improve your form step by step to become more efficient (hydrodynamic), so effortless paddling actually moves you through the water easily. Eventually you're swimming back and forth across the pool completely relaxed.

Another chapter teaches you to hit baseballs harder. Another chapter explains how to hold your breath for three minutes.

LIFE EXTENSION SECTION

First, Ferriss rejects calorie restriction as it's a miserable life. He similarly rejects restricting ejaculations (i.e., Dr. Strangelove). He rejects resveratrol because it interferes with estrogen. I stopped taking resveratrol because it interferes with thyroid function (I'm hypothyroid). He rejects some other life extension drugs. He recommends creatine monohydrate for preventing Alzheimers, Parkinson's, and Huntington's if your family has a history of these diseases. He also recommends intermittent fasting or just not eating protein for a day. He also recommends that men donate blood to reduce iron.

Ferriss doesn't talk about DHEA, the anti-aging hormone I take. DHEA is the most abundant hormone in the body. It's related to testosterone and estrogen but men and women have it equally. It peaks at 25 then gradually declines. Low DHEA is associated with many diseases of old age, and many studies have found DHEA supplements reverse these diseases in older people.

Ferriss recommends having SpectraCell Laboratories test you for nutritional deficiencies. He doesn't mention that they also have a telomere test. This tests your body's biological age, in terms of cell reproduction (i.e., how close your cells are to being unable to reproduce and your body wearing out). Lifestyle, e.g., diet and exercise, affect this. I'm going to get both of these tests done.

CONCLUDING THOUGHTS

This book isn't perfect or complete. But I'm giving it five stars because it gave me new ideas. I'm sure that an expert could pick apart any chapter and find mistakes or missing info. But that's OK. This book isn't the Bible; Ferriss doesn't want you to blindly repeat what he did. He investigated interesting ideas and saw what worked or didn't work for him. That's how you should use this book.

P.S. Several commentators have suggested that I write a book. I've written three books. Two are about stuttering therapy. My third book is "Hearts and Minds: How Our Bodies Are Hardwired for Relationships." It's written somewhat like "The 4-Hour Body" in that I present scientific research about relationships and then describe my experiences applying these ideas to dating and in relationships. Amazon sells all my books.

I had some friends over for a dinner for my fiance's birthday two days ago and one of my friends asked if my jeans were new. They weren't and, in fact, I had worn them several times around the same friend before. This time, however, the jeans actually fit and look great, like they're supposed to.

See, I was an athlete my entire life. Starting in my childhood, and through high school I played three organized sports, or more, each year. In college I played basketball several times a week with roommates. I was tall and lean and could eat without guilt no matter what. Once I finished college, however, everything began to change.

I landed a cushy desk job and moved away from my normal workout buddies, so I grew sedentary. Not being 100% sure on how to deal with my burgeoning waste-line, I delved into the popular P90X diet and workout regimen. Following the plan to the T, I transformed my body into something that I was truly proud of. Even when I was in the weight-room for over an hour a day and doing football drills for another hour a day in high school, I didn't look as good as a looked on the backside of the P90X routine. However, the whole think is a daunting task. Nearly 10 hours of workout time per week plus a very strict diet that requires a ton of time and energy just to count/portion/maintain. Luckily, I had a work schedule that lended itself to the lifestyle; but when I got a new job, P90X became impossible for me.

Over the next couple years, I lost the incredible body that I had after P90X and somehow got to a point where I was embarrassed to not wear a shirt. My clothes didn't fit well anymore and I was unbuttoning the top one (or sometimes two) buttons on my pants when I sat down! I was lucky enough to happen upon this book and sat in on a Q&A with Ferris, in which he encouraged me to do what works for me whether that's P90X or his new book 4-Hour Body. He said the trick was finding something that I could maintain - something that wouldn't cause me to YoYo.

I bought the book that day and began to read and understand what I needed to do to give his weight loss plan the ol' college try. First of all, Ferris tells you to choose the section that you are most interested in: fat loss, muscle gain, sex life, among others. He says to focus your attention on that one section for some time until you feel you are ready to move on. Clearly, I needed to focus on fat loss and I've been doing that for the past 6 weeks or so.

The chapters are easy to understand and the fat loss one clearly and concisely dispells some of the common misconceptions associated with weight loss. As an engineer, I looked to his testing and science for my peace of mind. The weight loss section talks about several aspects of his weight loss plan: 1) diet 2) supplements 3) temperature conditioning 4) there may be others.

I have really only implemented number 1) in my daily life, since they get progressively harder to make part of your routine as they go (2 is harder than 1, 3 is harder than 2, and so on). The diet is interesting, and most resembles a typical no-carb diet. These can be dangerous when done in long stretches (read: dangers of atkins), but there is a trick to this diet which I will get to in a few lines.

The other sections of the weight loss chapter are designed to get you through the last 5 to 10 pounds of loss that can be very tricky and stubborn. The last section is about managing and minimizing damage done during times of binge eating (holidays, days of weakness, etc).

Utilizing only the tips and suggestions and guidelines Ferris sets forth in the diet section of the weight loss part of the book, I am happy to say that I have lost just under 15 pounds, which is about 8% of my starting body weight. My face looks much more handsome since the bone structure is clearly visible. What's more is that my clothes fit me again! I don't feel disgusting anymore. I've dropped about 4 and a half inches off my waist and about 2 and a half off each thigh. What's more is this is all without stepping a foot in the gym.

Now on to the best part, I'm on a diet right now. This diet. But last Saturday, I ate 4 donuts, half a bag of cheetos, a Mexican pork dish, Spanish rice, some corn tortillas, and about 6 beers. Today (also Saturday) I've eaten a German pancake, corned beef hash, 2 eggs, some country-style potatoes, a package of thin mint Girl Scout cookies, some oreos, and a couple spoons of ice cream. You see, every diet has its cheat days. You always break down and cheat. With Ferris' diet, you MUST cheat once per week. In fact, it's a mandate, and without it, your progress will stall.

Right now, I am sitting in my living room, munching on cookies writing this review. I'm 15 pounds lighter, I wake up much easier in the mornings, I never feel bloated or fat or gross, I have more energy throughout the day, and I'm WEARING A BELT on pants that I bought when I was 21!!

Do yourself a favor and buy this book. Read it, learn it, and follow it. If it doesn't work for you, then it doesn't work for you. It's not miraculous, and it requires commitment, but it IS easy and maintainable. You can change the way you feel with this as your primary tool. You can change the way you look, the way you see yourself, and most of all you can change your life.
