Selouyanov on Endurance (Pt. 2): More Russian Sports Science from Dr. Smet

Guest author “Dr. Smet” finishes his insider’s tour of the Russian sports science underlying Pavel Tsatsouline’s long-awaited endurance training manifesto, The Quick and the Dead. I follow Dr. Smet’s blog Girevoy Sport After 40 to read about top-dog Russian coaching and research from a medical scientist who also practices what he reports on.

Before we start I have to make a disclaimer of sorts. Soviet sport scientists then and Russian scientists now often have fragmented interest and education in the field. Throughout his lectures Selouyanov makes statements that are debatable, to say the least, even though he doesn’t seem to have experience in the subject. For example, his view is tht the only way to increase the strength of the glycolytic muscle fibers is to lift maximal weights to failure. Therefore, if some powerlifters don’t follow that rule and still get strong – that must be steroids, no other explanation is possible. I am not qualified to argue the subject and am only conveying Selouyanov’s work, so take it or leave it. 

So let’s get to the most relevant parts of Selouyanov’s teachings. 

Muscle fibers 
Muscle fibers are loosely divided into three types, depending on the activity of the enzymes, in poarticular ATP-ase. Oxydative muscle fibers (type I) have slow ATP-ase, their speed of contraction is slow and they are resistant to fatigue. Glycolytic muscle fibers (type II) have fast ATP-ase, contract quickly and can be either resistant to fatigue (Type IIA) or not (Type IIB). 
For the purpoose of training muscle fibers can be looked at in the following way:
Oxidative fibers – have mitochindrial mass that cannot be developed further. Each myofibril is surrounded by a layer of mitochondria. These fibers use fatty acids in the active state. 
Intermediate fibers – have lower number of mitochondria. As the result two processes occur during activity: aerobic glycolysis and anaerobic glycolysis. During activity lactate and hydrogen ions are accumulated, so these fibers develiop fatigue, but not as fast as purely glycolytic type. 
Glycolytic fibers – have no or little motochondria, so that anaerobic glycolysis predominates, with the resulting accumulation of hydrogen ions and lactate. 

Factors that determine endurance

According to Selouyanov the difference in endurance can be fully explained by several factors. 
1) First, the development of the oxidative muscle fibers. Among well trained endurance athletes oxydative muscle fibers comprise 90 – 100% of the total muscle mass, therefore they don’t produce lactic acid in excessive quantities that cause significant acidosis and the resulting decline oin performance. To the contrary, among untrained individuals 50% of muscle consists of intermediate muscle fibers which, during their progressive recruitment during exercise, accumulate lactate. 
2) The second reason for better endurance among trained individuals is that their aerobic system switches on earlier, mostly because they have more oxidative fibers, so that the initial production of lactate is lower. 
3) Trained individuals utilize lactate more efficiently. Mitochondria are capable of utilising piruvate, and in the oxidative fibers piruvate is produced from lactate. 
 Fourth reason for better endurance – increased volume of the circulating blood. This, in turn, results in the reduced concentration of produced lactate.
The role of the heart. 
Endurance training leads to the dilatation of cardiac ventricles. This, in turn, makes cardiovascular system more efficient, in the way that the same cardiac output – the amount of blood the heart is capable of pushing though per minute – is achieved by fewer contractions. Training of the heart is a separate topic and will not be discussed here. 

Three types of exercises
All types of exercises utilised for the training of grapplers can be divided into three types. 

Effective exercises. 

  • Dynamic, maximal anaerobic power, to failure – facilitate the development of myofibrills in glycolytic and intermediate muscle fibers
  • Stato-dynamic, of maximal anaerobic power (100%), to failure (pain) – develop myofibrills in the oxidative and intermediate muscle fibers
  • Dynamic and stato-dynamic, of maximal alactic power, done to less than ½ of the limit, performed the light local muscular fatigue, repeated after normalisation of acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers
  • Dynamic exercises of near maximal power (90%), done to less than ½ of the limit, performed till light local muscular fatigue, repeated after the elimination of acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers
  • Dynamic exercises of submaximal (60 – 80%) power, done to less than ½ of the limit, performed till light local muscular fatigue and repeated after the elimination of excessive acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers

Harmful exercises.

  • All exercises of near or sub-maximal anaerobic power, as well as those of maximal aerobic power performed to the limit and causing excessive acidosis (pH < 7.1, lactate > 15 nMoll/L).

All other types of exercises have little useful effect for the development of endurance among grapplers. 
According to Selouyanov there are two ways to increase endurance and strength in skeletal muscle: increase the number of myofibrills and increase the number of mitochondria. Both are achieved differently in glycolytic (and intermediate) and oxidative muscle fibers, therefore we are left with four training modalities. 
In order to increase myofibrillar mass four factors must be present. 

  • Reserve of amino acids in the muscle cell (provided by consuming protein)
  • Increased concentration of anabolic hormones as the result of mental strain
  • Increased concentration of free creatine in muscle fibers
  • Increased concentration of hydrogen ions

Increasing the number of myofibrills in the glycolytic muscle fibers.
I suspect this part will make quite a few of us cringe. However, the goal of this post is to convey Selouyanov’s opinion on optimal training, so bear with me here. [Editor’s note: In effect, Selouyanov is about to ignore a core doctrine of Pavel Tsatsouline’s, namely the taboo against training to failure.] Glycolytic muscle fibers are activated when maximal muscular effort is required and no earlier. Therefore (according to the good professor), the growth of glycolytic muscle fibers can be achieved only by utilising weights of of maximal or near maximal intensity. The following conditions have to be present:

  • Intensity of maximal or near maximal intensity – more than 70% of 1RM
  • Exercise is performed to failure, i.e. to full exhaustion of CPn and achievement of high concentration of free creatine
  • Number of repetitions – 8 – 12. Last couple of reps have to be forced (with the help of a partner)
  • Rest – 5 minutes. Should be active, aerobic activity at HR of 100 – 120/min, this helps to utilise lactic acid
  • Number of sets: 7 – 9 if the goal is growth, 1 – 4 for tonic effect
  • Number of training sessions per day – one or two, depending on the intensity and athlete’s condition
  • Number of sessions per week – synthesis of myofibrills takes about 7 days, this is how long the athlete should rest after a training session done to the limit.

Myofibrillar hyperplasia in the oxidative muscle fibers
The method for developing myofibrills in oxidative fibers is similar to that for glycolytic muscle cells. With the exception that exercises are performed without relaxation. In that case the capillaries in the muscle are compressed, limiting circulation and leading to the hypoxia of the muscle fibers and the accumulation of lactate and hydrogen ions. 
I suspect this works similar to the occlusion (Kaatsu) training that became somewhat popular in the recent years. Selouyanov believes that mostly slow/oxidative muscle fibers grow under these conditions – Smet. 
To get the idea of this method imagine a barbell squat. Except that it is performed in the way that doesn’t allow for the pause at the top, with incomplete range. This way the muscles are continuously contracted to one degree or another, and after 20 – 30 seconds you get the burn, which is the desired effect. 
The conditions for the efficiency of this method are as follows: 

  • Intensity – medium: 20 – 40% of 1RM
  • No relaxation pohase during exercise, the muscles are continupusly contracted
  • Tempo and duration – slect the weight so that the athlete can perform 25 repetitions in 30 seconds. Last few repetitions should cause significant pain.
  • Rest – 30 seconds (active)
  • This exercise is performed in series of 3 – 5 sets. 25 reps in 30 seconds equals one set.
  • Number of series in one session: 1 – 2 for the tonic effect, 3 and more for growth.
  • Number of sessions per week – exercise is repeated in 3 – 5 days.

There is no mention of rest between series. I suppose it is several minutes, until the muscles feel relatively fresh.
Selouyanov recommends doing exercises aimed at growing muscle fibers at the end of the training session and better in the evening. If other types of training is done after this the reduction of glycogen can negatively interfere with the protein synthesis and impair growth. 
Development of mitochondria in skeletal muscle
Formation of mitochondria is controlled according to the principle of the functional criteria. According to this criterion, mitochondria that cannot properly function are eliminated. 
One of the natural factors leading to the destructurisation of mitochondria is hypoxia (e.g. being at altitude) and accompanying anaerobic metabolism. Similar processes occur during anaerobic training. 
Several generalisations can be made in regards to mitochondria: 

  • Mitochondria are energy stations of the cell and supply ATP by aerobic metabolism
  • Mitochondrial synthesis exceeds the destruction during conditions of their intensive functioning (oxidative phosphorilation)
  • Mitochondria tend to appear in the areas of the cells where the delivery of ATP is required
  • Intensive destructurisation of mitochondria occurs when the cell is functioning at high intensity in the presence of anaerobic metabolism which leads to the excessive and prolonged accumulation of ydrogen ions in the cell

Based on the above it is possible to develop methods of aerobic development of the cell. Every skeletal cell contains three types of muscle fibers. 

  • Those that are activated regularly during every day activity (oxidative)
  • Those activated only during training requiring moderate muscular activity (intermediate fibers)
  • Those that are seldom activated – only during maximal or near maximal effort, such as jumps, sprints etc. (glycolytic fibers)

In well trained individuals oxidative muscle fibers are maximally adapted. In other words, the number of mitochiondria in these muscles cannot be developed any more. It has been demonstrated that aerobic training at the level below anaerobic threshold in well trained athletes has zero value. 


Therefore, in order to increase aerobic potential of the muscle fiber it is necessary to build structural basis – new myofibrills. New mitochondria will then develop around these myofibrills. There is a special methodology which has been tested: interval training using two exercises. For example, pushups and pullups from low bar (unloaded, so that the feet are resting on the ground). 


General principles of such training are as follows: 

  • Exercises are performed at low intensity, i.e. 10 – 20% 1RM
  • Exercise is performed at medium or fast tempo
  • Full ROM is utilised
  • Duration – until early signs of local muscular fatigue
  • The template – 5 – 8 repetition of one exercise is followed by 5 – 8 repetitions of another without rest – that is 1 set
  • No pauses between sets
  • Number of sets – 5 – 10 (determined by the degree of fatigue) – that’s 1 circle
  • Number of circles in a session – 1 – 5 (fatigue and is determined by the glycogen stores in muscle tissue)
  • Session done at maximal volume can be repeated after 2 – 3 days, after glycogen stores are restored

Forty-Mile Ruck: Lessons Learned

To prep for the (in)famous Star Course, I tried a 42-mile ruck march.

I’d read one man’s AAR suggesting that in training you aim for 40 miles (64km) in something close to 10 hours, and on paper that sounded almost reasonable. It’s only 15 minutes per mile, right? Heck, I’ve motored along at that speed in perfect contentment for plenty of 12-mile marches with a 30# pack. So with just 20# dry (not even 10kg), wouldn’t I cover at least the first half of my journey at that pace? And if I allowed myself a full 12 hours, plus an extra hour for lunch, that would be almost leisurely! Right?

That was HUBRIS, and I got punished! Instead of treading a merry 13 hours, I slogged out a tough 15½ hours, and rather than a carefree and gay picnic walk, at times it felt like a death march.

This was a major lesson in all the factors that can slow a march down. Let me count the ways!

What I Did Badly

Feeling so sluggish, I sensed I was in for a long day. But I had no idea just how long.

First was my own poor condition. I’d been training hard, demanding a lot of my foot muscles (which work overtime in yoga and kettlebell lifting too), and the day before my ruck romp, I’d had a small migraine that I tried to cure by testing my rep max in the kettlebell snatch. (That worked pretty well, by the way.) Coupled with a 4am wakeup, it’s little surprise that I felt like hell when I started my walk, and it slowed me down. By mid-morning I was already an hour behind schedule. And that was before other adverse conditions started piling up.

I am blessed to live out in the country. Only problem is, my body thinks it belongs in a different country.

What other adverse conditions? Next was the heat, which is my personal kryptonite. I’m stocky and descended entirely from Northern European bog dwellers. Even in modest heat, a full sun clobbers me like an axe.

I made some poor nutrition choices too. Normally in these long events, I thrive on a scant 25g of carbs per hour and, being keto-adapted, I draw the rest of my calories from body fat. It’s a trick I got from ultra champ Zach Bitter and it makes me immune to the usual nausea and GI trouble of endurance events. But on this morning I treated myself to a big, sugary frozen mocha, and it was way too much carbs and gook. I’ll spare you, gentle reader, an account of the results and just summarize them as “sub-optimal.” Lesson: Just 25g of carbs per hour.

If you want to geek out on this stuff, read the work of Mike Prevost.

By my choice of routes, I also gave myself a (poorly timed) lesson in how much you can be slowed by terrain. The Army has researched rucking speed and found that, even more than pack weight, you’re slowed by factors as mundane as the ground’s surface. And elevation gain is another biggie. When climbing a 10% grade, you cut your speed in half. (EDIT: Researcher Adam Scott finds that it’s only a one-third reduction.)So on one steep 4-mile stretch, I climbed for almost two hours.

Nor did I factor in stream crossings. Foot care guru John Vonhof insists that you remove shoes and socks at streams, carry them across, and dry your feet before putting them on again. I did this each time, dutifully but grudgingly, but I ate up nearly an hour and disliked feeling my way painfully across the stream bottom in sore, bare feet. Lesson: Bring water shoes and a microfiber hand towel. On trips where I’ll recross the stream at the same point, I can even stash them near the crossing to wait for my return trip.

Finally, maybe it wasn’t the best idea to wear brand-new boots. Though they didn’t need much breaking in, they still required time-consuming experimentation on the trail, trying different combinations of socks, liner socks, and lacing.

Ridiculous math like this is an example of why the metric Mondopoint system is so great. You measure your feet in millimeters. That’s your size. Simple.

However, there was one thing about these boots that was a godsend: they’re actually big enough! My toes have never been so free. I owe this too to John Vonhof, whose simple trick is to remove the insoles from your shoes, set them on the ground, and stand on them. If your feet lap over the insoles at any point, or even touch the edge, the shoes are too small. That’s how I went from a size 9.5 to a 10.5 Wide!

What Went Great

Aerobic base: Aerobically this trip posed little challenge. As in all my training, I throttled back enough to stay within my “MAF” heart rate (“max aerobic function”). And even on such a long ruck, I found, as long as I stay within my MAF heart rate, I can put my legs on cruise control and motor along indefinitely. My feet might get sore, but my heart and lungs can hack it just fine.

Our Lady of Electrolytes and Mr. Delirium

Electrolytes: At long last, I didn’t cramp! I can’t take credit for this. The unsurpassable Lean Solid Girl met me at my turnaround point with a princely feast of burritos, trail mix, cold drinks, and (best of all) electrolytes.

Blisters: I only got one blister, on my heel. Zero blisters would be better, but I’ll take this as a victory considering this was a distance PR in boots that were new out of the box.

The Great Takeaway

The home stretch. From this bridge, it’s 3 miles to my door. The last time I passed it feeling this tired was only a few months ago. That night I was doing my first 12-miler, but now that’s just a warmup. Reflecting on that was a real morale boost. #cookiejar

I didn’t quit. That’s the great takeaway. At 5:30am, only 5 minutes into the day, I still had a lingering headache from the day before, felt like hell, and had no spring in my step, and I thought, “I picked an awful day to do this. It will be amazing if I actually finish 40 miles today.” And I was right on both counts: it was terrible timing–WTH kind of plan is “be sick all day, then max out on snatches, and then do 40 miles the next day?!”–and it’s amazing to me that I finished it. I should have rescheduled–stupid stuff is stupid, and it would have required effort to choose a worse day for this. But once I (foolishly) committed to it and decided to stick with the (dumb) plan, it was almost a certainty that I’d finish–eventually–as long as I didn’t quit.

Rucking up at Mile 23. Don’t believe the smile, it’s a lie. I’m feeling pretty sorry for myself here. Out of the frame, milady’s Prius is whispering, “Give up! I’ll take you home right now. How about some air conditioning?”

And that, friends, is the big lesson. (Cue the “rousing emotional crescendo music!”) It seems that in an event like this–a low-intensity slog played out over a very long time–there’s almost no way to suck so much that you can’t finish. There’s no opponent to KO you, pin you, or steal the ball, and you need zero coordination or athletic talent–it’s just walking. Physically the demands aren’t even very intense or the perils great: you won’t get a concussion or cascade off the side of Mount Everest. You can suck as much as you want for as long as you want, but unless you decide to quit (or you get abducted off the road by a UFO), you are pretty much assured of succeeding eventually. As Goggins says, “No talent required.”

A Farewell to Fatigue: How to “Fragment the Load”

Did Hemingway invigorate himself to run with the bulls in Pamplona by blowtorching his lungs doing Crossfit? Hell no. Papa knew how to pace himself.

Part 5 in our series “Tao of the Lazy Badass.” Find the first four installments here, here, here, and here.

You already know the First Law of the Lazy Badass: “Do a lot of volume while minimizing fatigue.” Today we teach you how to minimize fatigue.

When you accumulate volume (i.e. total reps), you’re depositing money in the bank. The deposits seem small and insignificant, but you make them often and with no sense of sacrifice. That’s important: we want you refreshed by your workouts and recovered quickly. That way you’ll crave your next bout of exercise—you dirty endorphin junky!—and you’ll be fresh and ready to hit the iron or the trail again ASAP. That is why the lazy badass minimizes fatigue.

Sounds great in theory. But how do you maximize volume without also building up fatigue? Get ready, because here comes the second big secret …

Fragment the load

“That’s pretty gnomic,” you might be saying. “WTF does that mean?” It means that you should space out the work. Chop it into bite-sized pieces.

Let me start with an example of the WRONG way to do a lot of volume.

Gironda was not a tactful man.When the Iron Guru first met a young unknown named Schwarzenegger, who announced his intention to become Mr. Universe one day, Gironda sneered and retorted, “You look like a fat fuck to me.”

In popular muscle media, there’s a renaissance in people writing about “German Volume Training,” the (in)famous bodybuilding protocol that, despite its name, probably originated in Hollywood with Vince Gironda, preceptor to the young Arnold Schwartznegger and “Iron Guru” of bodybuilding in the 1950s and ‘60s.

Vince taught trainees to rack up a lot of volume—so far so good!—but he made them hurry through that at a breakneck pace with very little rest. He prescribed a whopping 100 total reps per exercise, done in 10 sets of 10 with just 30-60 seconds of rest in between. That’s massively fatiguing. And you have to settle for using wimpy weights, because you can’t complete that protocol with even moderate poundages. And you will need days to recover from it. And it’s the opposite of fun and refreshing. It takes great willpower to do it even one time, and you will NOT look forward to doing it again. 

Fatigue sucks, and that’s why it is contrary to the Tao of the lazy badass to rush through volume with little rest, a thundering pulse, and buckets of sweat. To delay fatigue and accomplish more total work, the lazy badass fragments the load by breaking it up into many short sets. Instead of completing your sets and reps quickly, space them out. For example, instead of blowtorching the muscles with high-fatigue sets of 10 reps, an aspiring lazy badass could do the following:

Set up a clock near your kettlebell / barbell / whatever. At the top of every minute, do an easy 4 reps. That might only take you 10-20 seconds, and that’s fine. Rest for the remainder of the minute. At the top of the next minute, do your next four reps. Keep repeating, making haste slowly. While your friend attempts the German Volume protocol with his trachea on fire, you’ll be happy as a clam. As the minutes tick by, not only won’t you tire out, you might actually feel stronger and zestier than when you started.

Training “on the minute” is associated with Scott Sonnon, the martial artist who brought back exercise clubs in this country.

Your friend will be very lucky to complete his 100 reps at all; but you’ll cruise along contentedly, til after 25 minutes you’ve cranked out your 100 reps and gotten high on endorphins too. And if you start to tire before then and your heart rate starts to climb, no problem! Just drop down to 3 reps per minute. Or even 2 reps. There is no time limit here! Your only job is to accumulate volume, and there’s no penalty for doing it slowly. 

This “on the minute” protocol is only one of the many proven ways for a lazy badass to fragment the load. In our next installment or two, we’ll talk about some of the other techniques. You can pick the one that suits your schedule and your pace the best. It makes little difference. They all follow the Tao of the Lazy Badass (which, once again, is to maximize volume and minimize fatigue) by breaking up the work into small, enjoyable packets with lots of rest smeared all over, like butter on pancakes. 

“Those the gods would destroy, they encumber with a TRX instructor”

It’s always some heavily muscled personal trainer. My toughest moments at Goruck challenges are when I must fireman’s carry a teammate, and it’s never the vegetarian triathlete who works for a socially conscious startup. I always get the dense, hypertrophied Paleo stevedore-type who runs a gym.

It’s amazingly easy to fireman’s carry someone, but it’s surpringly hard to keep it up for long. So today’s game was called “Desmond Down,” in honor of the barrel-chested personal trainer whom I had the horror honor of helping to carry for the last mile on Saturday, when he was suddenly designated a “casualty” by cadre fiat. I trudged up the Rock of Faeries shoulder-carrying the 150# sandbag.

You’d expect the climbing to be the worst part, and you’d be right, but I was surprised by just how hard–I’ll bet the last 150 vertical feet took close to an hour. And it wasn’t much easier to lift the bag onto the shoulder in the first place. In both cases, the golden rule seems to be keep your hips directly under the bag. “Duh,” right? But you can let the hips drift without noticing, and even a couple of inches increases the stress and heart rate.

I’ll do this one again, but not on rocky slopes. I have plenty of good training ideas that don’t risk falling on igneous rock, and if I had attempted this in the shallowly-treaded Goruck boots, I’d be blogging from Valhalla right now.

D-Day

Today’s the day, friends. 24 hours, 40+ miles, with logs, sandbags, PT beatdowns, and surf torture along the way.

Wherever you are today, get after it! Hammer along with me and (I’m completely serious about this), please remember my team and me in your thoughts and prayers. I may be Buddhist, but I’m not choosy about where I get my numinous intercession.

The Tao of the Lazy Badass

“Like water, volume is soft and yielding. But volume will wear away rock, and it beats the crap out of excess fatigue. As a rule, volume wins over fatigue. This is another paradox: what is soft and voluminous is strong.”

from the lost training manual of Laozi (Lao-Tzu)
A difficult book, but the most important one I know.

In the most original book on training in decades, Pavel Tsatsouline describes a certifiable badass, a special operations ninja-type whom he pseudonymously calls “Victor.” Victor combines a pair of already-extraordinary feats into an extra-extraordinary combination: he runs ultra-marathons of up to 100 miles AND he does pullups with an extra 160# hanging from his waist. That’s a freakish level of endurance and world-class strength, a combination so rare as to seem impossible. (As we have said before, strength and endurance are rivals.) That is what makes Victor an elite among the elite, a certifiable badass.

To reach those heights, Victor trains in a very special way: lazily. Or to be more precise, with low fatigue. From his amazing accomplishments, you might suppose that he spends all day exercising and puking his guts out. Nope. Most days he works out for all of 30 minutes, much of it with a 24kg kettlebell, which is strictly a “Joe Average” weight, and some pushups and pull-ups and yoga. He left behind even low-key barbell training long ago, explaining that when he deadlifted, “I felt my ego pushing me harder and faster than my body wanted to go. So I decided to limit myself to one kettlebell and two [steel exercise] clubs …”

As the core of his lethargic-looking super-routine, Victor runs … sloooooowly. Slowly enough to breath only through his nose, with rhythm and relaxation. He writes:

“The key is … the LOW INTENSITY. I use a heart rate monitor, and I stay at 60% to 65% of my [max heart rate]. This means that I am often walking on the hills. If I ran [faster], my recovery time would be much longer.”

Allyson Felix knows the Tao of the lazy badass. Her coach, Barry Ross, keeps his athletes fresh and unfatigued in training. See Easy Strength.

Pavel and Victor are insistent: Victor is not succeeding in spite of his low-key training but precisely because he throttles back. Victor has perfected one way of applying the near-magical formula for productive and happy training: do as much work as possible while staying as fresh as possible.

Are those twelve words too much to remember? Then stencil this on your kettlebells, barbells, and running shoes: Volume Without Fatigue. That is the red thread that runs through many of the successful training philosophies out there, connecting disparate-looking approaches whose only apparent link is that they work well, and it is the subject of our next series, “Farewell to Fatigue: The Way of the Lazy Badass.”

Your author. Not a badass, but I make up for it in laziness.
