Summary
Mark Sisson has a great new book out called Primal Endurance and if you re an endurance athlete, if you're on marathons, triathlons, or do obstacle course races, this episode is for you! In this episode, Mark and I discuss some of the myths about training for endurance events, some of which are: You don't need a carbo load the night before your event, you don t need to eat pasta the day before your race, and you shouldn't be running faster than you should be running.

brett mckay here and welcome to another edition of the art of manliness podcast so you probably
00:00:18.660
heard of the paleo diet primal living etc it's got a whole bunch of different types of names
00:00:22.080
one of the driving forces behind this movement is a guy named mark sisson he's got a website
00:00:26.060
called mark's daily apple if you haven't been there go check it out there's a lot of great content on
00:00:30.680
fitness and just health in general anyways mark's got a great new book out called primal endurance
00:00:36.000
and if you're an endurance athlete if you're on marathons triathlons do obstacle course races this
00:00:40.160
episode is for you today on the show mark and i are going to discuss some of the myths about training
00:00:46.500
for endurance events some of those being you don't need a carbo load right have the big bowl of pasta
00:00:52.480
than the night before your event in fact that can actually hurt your uh your progress and your
00:00:57.680
performance we also discuss how you know training for endurance events and how you probably shouldn't
00:01:01.800
train as hard as you are training in fact you're gonna have to run slower than you think you should
00:01:06.000
run and sometimes may even have to walk uh today on the show mark's gonna explain why that is and
00:01:11.400
give specific ways examples protocols on how to train how to eat what to do for recovery so you can
00:01:18.820
have you perform your best not only perform your best but enjoy your endurance sport for as long as
00:01:23.920
you can uh so great show make sure to check out the show notes after the podcast is over at aom.is
00:01:30.640
slash sisson where you find links to resources and things we mentioned throughout the show
00:01:35.740
mark sisson welcome back to the show thanks brett back after how many years uh since 2009
00:01:46.400
it's a long time pal we've been growing we have you've grown phenomenally since then like last
00:01:51.840
time we talked uh your blog mark's daily apple had just gotten started all about primal living
00:01:58.300
um and you're out with a new book uh for endurance athletes for people who do triathlons marathons
00:02:05.780
long distance bicycling those crazy people who do the ultra marathons um it's called primal endurance
00:02:12.240
and the latest one obstacle racing obstacle racing i'm a big fan of the obstacle racing
00:02:16.260
yeah i'm i don't like just running i like being i have my running interrupted with peg boards and the
00:02:23.220
like i'm hip i mean if if that had existed you know 40 years ago when i started competing at an elite
00:02:28.900
level that would have been my sport i guess but anyway here we are here you are but so yeah primal
00:02:34.280
endurance this is interesting because you're going back to your roots with this book you started off
00:02:38.900
uh your career your athletic career as an endurance athlete uh for our folks who aren't familiar with
00:02:44.380
that tell us about your background as an endurance athlete what did you do uh i was a distance runner
00:02:49.720
uh primarily a marathoner and uh started out of necessity i grew up in a small fishing village in
00:02:55.340
maine i had to had to hike or walk or run two miles each way to school um and just figured that running
00:03:03.180
would get me home faster so i i started running at you know 11 12 13 years old and
00:03:08.380
joined the high school track team wound up doing pretty well in the mile in the two mile events
00:03:12.940
um rolled that over into college where i was captain of the cross-country team started doing road races
00:03:18.980
in the summer uh got out of college was uh good enough at running that i thought i would train for
00:03:24.160
the 1980 olympic trials so i spent the next several years focused on running uh putting in 100 miles a
00:03:30.740
week for many years uh got to be pretty good i finished fifth in the u.s national championships in 1980
00:03:35.440
and um so yeah i was uh i was down this path of um of human performance but ironically i started down
00:03:44.100
that path with an eye toward improving my health and longevity and as i got further and further down
00:03:50.680
that path it became fitter and fitter and more uh able to able to run faster and compete at a high
00:03:57.960
level i found that my health was suffering and that was a little bit of a disconnect because i'd assumed
00:04:03.120
all along that the more you ran the healthier you became and the better your heart was and the
00:04:08.380
stronger your joints were and so on and so forth but that wasn't the case so uh at the end of uh
00:04:15.780
around 1980 i um i was forced to retire from marathoning my injuries i had osteoarthritis i had
00:04:23.180
tendinitis had all sorts of injuries that had piled up and i was getting sick a lot and i had irritable
00:04:28.120
bowel syndrome and i was just a wreck really so i retired from that that high level competition
00:04:34.240
and and devoted kind of myself to figuring out ways in which i could i could be fit and and healthy at
00:04:40.840
the same time and and that's what i've spent the last 36 years investigating and doing and ultimately
00:04:47.800
i came to this point um about four years ago where i realized there is this this convergence of
00:04:54.680
technology now where we find that we can create the ultimate sort of high performance athlete and
00:05:00.680
not sacrifice health and that became the impetus for my new book primal endurance okay and what's
00:05:07.120
interesting is that primal endurance it shows athletes how to like you said be the optimal athlete but it
00:05:14.000
breaks or shatters a lot of myths it goes against the grain from what you've heard if you grew up in
00:05:20.060
the 80s and 90s about what you need to do to be an endurance athlete and i think it's interesting
00:05:26.020
too like you said you had these you were you were fit like you could run long distances quickly um but
00:05:32.160
you felt terrible and but this this is something that's common in the endurance uh world or was common
00:05:37.980
is becoming less common now uh what is it about endurance training the way people typically do it that
00:05:44.240
makes them feel terrible well first of all it's this um you know it's like a badge of courage to tell
00:05:51.880
somebody you're a marathoner or a ironman triathlete or or some ultra runner that uh people go oh my god
00:05:57.500
you must what discipline you must have and what strength you must have and and that's pretty much
00:06:02.420
true because it you're it's half the time you're out there most of the time you're out there you are
00:06:06.340
managing pain you know you're uh you're struggling through these workouts and you're and you're and you're going
00:06:12.180
to the well in these races digging as deep as you can um it's it's never you know i don't know of
00:06:17.820
anyone who's an elite level racer whoever says oh i was having so much fun out there right um and yet
00:06:23.520
you talk to elite basketball players elite football players elite soccer players they'll tell you what a
00:06:27.520
blast they were having on the pitch but with endurance athletes it's more of this um stoic kind of uh
00:06:33.300
management of pain and and it was an assumption that we all had that in order to race fast you had to a
00:06:39.500
train fast b you had to practice suffering i mean that was really what it was like in the mindset was
00:06:46.600
you know if i didn't suffer today in my workout the workout was not worth doing and so for decades we
00:06:53.600
went out and we put all these miles in and we raced we ran literally as many miles as we could at the
00:07:00.240
highest possible level we could with the heart pounding as high as we could sustain um and with the joints
00:07:08.100
being able to maybe keep pace uh without getting injured so it was really what's the you know
00:07:13.520
what's what's the highest amount of pain threshold i can create for myself in my training and sort of
00:07:18.360
practice that on a daily basis so that when i get into a race i'll be able to you know recreate all
00:07:24.940
this uh uh pain but management manage it in a in a better way and it's foolish to think that that
00:07:30.840
that's that's kind of how we train now ironically we also um we we sort of understood through
00:07:37.920
conventional wisdom that the way to fuel all this activity was to take in lots of carbohydrate because
00:07:42.500
the understanding was that when you manage your carbohydrate intake and you manage your glycogen
00:07:47.240
stores that's how you become an elite racer that's how you become a better at at racing at whatever
00:07:53.780
level you're at so that that sort of begat this whole concept of carbo loading and all of the gel
00:08:00.580
packs and all of the drinks the the pre-race drinks the the during race drinks and all that stuff was
00:08:06.200
was basically contemplated to get more and more sugar into your system so that you could you could
00:08:12.060
burn more glucose and sort of put off hitting the wall for as long as you could well those two things
00:08:18.280
the the intense mileage and the uh focus on carbohydrates and particularly on sugar kind of
00:08:25.360
overlooked the the main focus of what we should be looking at with endurance training which is
00:08:30.980
how do i manage glycogen by burning fat really well how do i become more efficient at burning fat so
00:08:37.400
that i don't have to put in a lot of carbohydrate that i don't have to put in a lot of sugar and once
00:08:42.480
you realize that fat is the preferred fuel for humans in general and that it becomes a preferred
00:08:49.360
fuel for humans who are competing uh once you understand this you can then begin to take on a
00:08:55.920
program a training program that reconfigures your fuel partitioning so that you get most of your energy
00:09:03.300
from fat at reasonably high levels of output uh that you spare glycogen that you don't put so much
00:09:11.100
of this inflammatory carbohydrate and sugar and and grain stuff through your through your digestive
00:09:17.900
track and your body and lo and behold you become a more efficient runner because you're burning fat
00:09:23.700
at a higher rate and you become a less injured runner because you're not getting that inflammation
00:09:28.300
that chronic inflammation that consistently goes with with the training and because you can do so on
00:09:34.540
on a uh on slower training and we'll get to that a little bit and it turns out that we were
00:09:40.460
training at way too high way too high a heart rate and too fast a pace to become efficient the only way
00:09:46.040
you become efficient at endurance training is to manage your heart rate in a in a completely aerobic
00:09:52.500
zone which means at a much more comfortable pace so now all these things come together now you're
00:09:57.840
you're actually you become a better racer by training slower strategically of course uh by adapting your
00:10:05.080
athlete your diet so that you become better at burning fat and when you become better at burning fat
00:10:08.960
you burn off your stored body fat so now we get to the point where you've got an ideal body
00:10:14.760
composition so many runners i see at the beginning of a marathon brett and they're like seriously dude
00:10:20.600
you got 25 or 30 pounds to lose and you're entering this marathon and you tell me you're training 30 40
00:10:25.560
50 miles a week how come you're not losing the weight well that's because they haven't become good at
00:10:30.400
burning fat so we we're training at a much kinder gentler pace we're eating the sorts of foods that
00:10:37.320
encourage us to burn off fats we're getting injured less often and sick less often because of this
00:10:42.900
reduction in inflammation and and oxidative throughput and it all comes together to make
00:10:47.880
for a strong lean fit happy healthy productive athlete yeah that's fantastic there's a lot to
00:10:54.580
unpack there and i thought that was interesting that statistics i've read that other where other
00:10:57.540
places where they did a survey and they found that 30 of all marathon uh participants like they're
00:11:03.700
overweight which is that crazy you think like these like marathon they can run 26 miles they're probably
00:11:09.200
the fittest people in the world but a lot of them are overweight correct and they're overweight by the
00:11:13.240
way they're overweight because they're stuck in this carbohydrate paradigm and the way it here's how it plays
00:11:18.220
out you know you train really hard but because you're not burning fat at a high level you're still
00:11:22.900
burning through all of your glycogen every every workout you do uh you get home the brain says hey we
00:11:29.060
just depleted all the glycogen we better build back our glycogen stores we better eat all the
00:11:33.360
carbohydrate we can get our hands on so you carbo load that night and then the next day you go oh well
00:11:38.400
i carbo loaded i better go out and train again train hard and it's this vicious cycle well the brain
00:11:43.180
sort is telling you to overcompensate by replenishing the carbohydrates after a fashion and it gets to the
00:11:50.960
point where every excess carb that you take in raises insulin and is sort of presumptively going
00:11:57.240
toward fat stores once the glycogen stores are filled and you have this this vicious cycle where
00:12:02.480
you think wait a minute i just sweated off 500 calories today and and every day for the last uh
00:12:07.600
you know year and a half you're telling me i haven't lost any weight what's wrong with this picture well
00:12:11.980
what's wrong with this picture is you haven't become good at burning fat yeah that's the chronic
00:12:16.480
cardio that you talk about in the book exactly so let's let's talk about let's get into this difference
00:12:20.640
so the difference between aerobic and anaerobic training because i think most people think oh yeah
00:12:24.600
yeah running bicycling those are aerobic activities and they think of like lifting weights as an
00:12:29.700
anaerobic activity but what you argue in the book is that many endurance athletes who think they're
00:12:35.980
training aerobically are actually training anaerobically right so we're always doing a mix
00:12:43.080
of aerobic and anaerobic energy production so at the very lowest levels it's 99 aerobic using oxygen
00:12:51.700
using oxygen to burn fat so walking around the house uh uh easy easy jogging easy swimming whatever
00:12:58.660
when your heart rate's just creeping up there you're in a mostly aerobic zone uh as you start to increase
00:13:06.560
the speed the pace as you start to increase the workload as the heart starts to beat harder you
00:13:11.900
enter a little bit more of an anaerobic contribution and that is the uh the burning of glycogen uh through a
00:13:19.680
process known as glycologist glycolysis and so there's a little bit of fat burning and then some
00:13:24.820
glucose glycogen uh burning and as you increase the pace and increase the the rate of heart rate
00:13:30.740
it becomes less aerobic and more anaerobic and that's that part that starts to the anaerobic part is what
00:13:37.860
we see when we start to build up lactic acid and we start to get out of breath because we can't
00:13:42.880
we can't keep up aerobically we can't bring in oxygen enough to just do this with an aerobic oxygen
00:13:50.540
based uh level so where we see so much happening with uh with endurance athletes is because they can
00:13:58.900
train at a high heart rate uh they choose to do so thinking that at the higher heart rate that i can
00:14:04.820
maintain in my training for an hour hour and a half whatever the better that must be for me but what
00:14:11.080
it's doing is it's reinforcing this anaerobic type of training which is that training which puts you
00:14:16.980
into that lactic acid buildup phase that that takes you away from the aerobic training so the first sort
00:14:27.120
of lesson that we learn in primal endurance is where's that sweet spot where i can train my heart at
00:14:33.760
its highest possible rate but still mostly aerobic and it turns out that it's a number that's proven
00:14:41.220
empirically over the last 20 years to be 180 minus your age plus or minus a few beats based on genetics
00:14:47.920
and and and predispositions and and perhaps your your your athletic history but 180 minus your age
00:14:54.820
so in my case i'm 62 uh so 180 minus 62 is 118 so 118 is the highest heart rate that i
00:15:03.480
should be holding in long uh endurance efforts if i'm on the bike if i'm hiking if i'm jogging if
00:15:10.260
i'm um you know wandering around the house quickly or whatever i'm doing 118 is that heart rate for me
00:15:17.740
at which i'm putting mostly oxygen through my body and i'm not entering into any anaerobic
00:15:23.120
contribution now what a lot of people find is because they've trained so hard for so long
00:15:29.260
that and like i'm a person i could if i wanted to brett i could go hold 165 beats a minute on the
00:15:36.140
bike for 20 minutes or 30 minutes or maybe longer but it's not efficient at that at that rate i am not
00:15:43.620
burning mostly fat i'm burning mostly carbohydrate and i'm and i'm reinforcing that whole energy system
00:15:50.300
of carbohydrate dependency and i'm not becoming more efficient at burning fat so with that 180 minus
00:15:56.300
your age which in my case is 118 beats a minute that's the maximum heart rate that i can go at now
00:16:00.980
if i people say well mark i tried your program and i can usually run 7 30 miles but you know
00:16:07.820
when i met when i limited my heart rate i wore a heart monitor and i didn't let my heart get above
00:16:12.820
say 140 for a for a 40 year old i was going like 13 minute miles what's up with that i can go a lot
00:16:20.420
faster than that well what's up with that we just proved that you are not very good at burning fat
00:16:25.500
we just proved that you are not very aerobically efficient so in primal endurance in the book we
00:16:30.920
talk about one of the strategies for becoming more aerobically efficient is to limit your heart rate to
00:16:35.380
that number for most of your base training don't exceed it if you do not for not for very long
00:16:42.500
and over time you'll find that your efficiency improves so that same person who was running 12 or
00:16:47.060
13 minute miles over time is now going well wait a minute now it now at my 140 maximum heart rate
00:16:53.180
hey i'm doing 10 minute miles or i'm doing 9 30s and then a month later wow i'm doing 8 30s what
00:16:57.840
does that mean well what that means is that they're doing 8 minute and 30 second miles burning mostly
00:17:02.880
fat burning 97 98 fat so that when they go ramp up the next phase of their training to to become
00:17:11.640
faster and and uh and more and more powerful if you will uh they're starting at a much higher base of
00:17:19.060
fat burning which will benefit them when they get in a hard workout or they get a race against
00:17:24.680
somebody who's not as efficient as they are does that make sense that makes sense so you got to slow
00:17:28.240
down to speed up in the long run i mean that's the mantra and it's it's counterintuitive at first but
00:17:33.600
when you understand the biomechanics and the biochemistry of it uh you can see that if we're
00:17:37.780
talking about becoming more a more efficient fat burner and if we understand that fat is this preferred
00:17:43.540
fuel that we want to tap into so that we can we can better manage our glycogen stores and spare
00:17:49.720
glycogen because there is this science that suggests that once the muscles are out of glycogen
00:17:55.560
you hit the wall so now if i'm if i'm running at the same pace as the competitor next to me
00:18:02.020
but i'm burning at the pace that we're at i'm doing i'm getting 80 of my uh my energy from fat and 20
00:18:08.480
percent from glycogen and that person is getting 40 of his energy from fat and 60 from glycogen at
00:18:15.080
the same pace who's going to run out of glycogen faster he is now so that so if we if we go to the
00:18:20.620
same pace he'll die he'll hit the wall before i do but conversely if i want to match his his his fuel
00:18:27.080
uh uh partitioning and i want to go 60 uh or 40 fat and 60 glycogen i'm going to be going a lot
00:18:34.340
faster than he is from the get-go because i'm that much more efficient okay and so i mean i imagine
00:18:39.520
this when people hear this and they put it into practice first it's extremely frustrating like you
00:18:44.340
might be doing a lot of walking during your if you're a runner yeah yep right or as we say on
00:18:49.360
the bike you may be doing some paper boy up the hill um but uh then that's zigzagging back and
00:18:54.820
forth across the street with a with a bike full of papers back in the old days i don't know if that
00:18:58.380
means anything to your audience but uh it's a it's a cool visual for those of us who are over 50
00:19:03.060
um but it basically yeah i've had so many people uh report back to me exactly that wow i was so
00:19:10.460
frustrated when i first started doing this it's like i i wasn't going that fast i didn't feel like
00:19:14.920
i was doing much but i'll tell you what after you know a month of doing this i'm racing faster than
00:19:20.560
ever and i'm not even doing any speed work what's up with that what's up with that is you're racing
00:19:24.960
you're more efficient you're burning more fat so that when you do get to the high end
00:19:28.500
you've got more glycogen to spare than the guy sitting right next to you who hasn't been training
00:19:33.160
that way this is fascinating so before we get to the nutrition because that's connected to this
00:19:38.040
let's continue with the training because one of the other things you talk about in primal endurance
00:19:42.660
that sort of goes against the grain of what you're traditionally here in endurance sports is
00:19:48.040
this idea strength training should be an important part of an endurance athletes programming and not
00:19:54.040
just like any type of like i think most people when they think endurance athletes doing strength
00:19:57.920
training they think maybe some barbell you know some dumbbells some lunges but you're recommending
00:20:03.300
like barbell training like deadlifts and and uh squats i mean right so if you're a runner or cyclist
00:20:09.340
it would be those uh the lower body stuff that the the complex complex exercises like weighted squats
00:20:15.780
and deadlifts and the reason is uh it's to develop uh sustained power so what happens in a race a couple
00:20:24.780
things happen when you're when you're competing one of which is certainly that ability to produce energy
00:20:30.300
at a more efficient rate and to fuel the muscles but the muscles still have to have the ability to
00:20:36.220
withstand the demands of increased uh output whether it's uh sprinting whether it's climbing hills as a
00:20:43.640
runner or climbing hills as a cyclist and what we see happening over time particularly in the longer
00:20:48.700
events is that athletes may have a hundred percent of their max power on the first hill but then the
00:20:54.380
second hill rolls around and even though their energy production is is reasonably good the muscle
00:21:00.420
fibers themselves are starting to tap out because they haven't trained for this ability to sustain
00:21:06.480
power over time uh and so we see cyclists who'll maybe climb the second hill at 75 or 80 percent of
00:21:13.560
their max capacity or max power and then by the time the third hill rolls around they're at 65 percent
00:21:18.380
so how do we how what can we do in terms of training to increase that ability to sustain power over the
00:21:26.540
long haul and what we do is we load those those muscle fibers uh deeper and deeper we put more stress
00:21:33.500
on them in a short period of time through specific things that we do in the gym for example
00:21:38.240
uh we might do weighted squats and we might determine well what is my you know one rep max
00:21:45.960
on a squat and let's just say if you're an endurance athlete it might be say 100 or 200 pounds
00:21:51.100
well then we take 80 percent of your one rep max we call that 160 and instead of doing one rep and
00:21:57.500
stopping or conversely instead of doing say um 80 or 100 pounds 20 or 30 you know times 10 reps times
00:22:07.120
three sets and then walk away we take a we take a hybrid of that and we go okay 80 of your one rep max
00:22:13.200
we're going to do a couple of we do as many as we can uh right now do a quick 10 second rest uh don't
00:22:20.220
don't even re-rack the equipment or don't really walk away from it uh do a couple more uh maybe take a
00:22:25.740
short rest there do a couple more and we keep loading those fibers until we can't complete one more
00:22:31.360
rep with perfect form and form being the sort of main arbiter here so what we're doing is we're
00:22:37.720
we're loading the fibers and then we're backing off a little bit and then we're loading them again
00:22:42.980
and backing off a little bit but we're loading them maximally so we are we are recruiting fibers
00:22:49.860
deeper and deeper into that muscle tissue to the extent that those fibers become able to handle
00:22:54.960
uh the power demands that may be called upon in a sprint uh halfway into a bike race or a or a hill
00:23:02.760
climb a charge up the hill or heartbreak hill at uh at the at the boston marathon or something like
00:23:08.780
that so these are we're basically we're training the component parts of what a race consists of but
00:23:16.680
doing so in a way that rather than just practicing doing them we are breaking them down we're parsing the
00:23:22.860
entire uh the entire goal into its component parts so that we're dealing with the aerobic efficiency
00:23:30.580
we're dealing with maximum sustained power uh we'll talk later about sprinting and and how we look at
00:23:37.040
sprints as a form of interval training and then ultimately we'll look at how the diet is important
00:23:42.680
in in reconfiguring how we extract fat from uh from our stored body fat so uh how do endurance
00:23:49.400
athletes avoid the risk of bulking right while doing strength training because like you know
00:23:54.480
on cyclists runners like every little bit like if you if you sure you have more muscle and that muscle
00:23:59.860
can do more work but that's like more weight you have to carry around um so how do you uh address
00:24:05.460
well first of all yeah so if we're doing lower body training in the gym um you're not you know you're
00:24:12.520
not bulking up on top so you're not really carrying around any extra weight on top we're not having
00:24:17.640
you do biceps curls and you know and lat pull downs and uh you know deltoid raises and things like that
00:24:24.580
i mean you can if you want to but that's not the point here the point here is is how specific can i
00:24:29.480
get in my in the gym in the weight training so that i'm building power and not putting on useless mass
00:24:36.440
around my entire body so when we're talking about doing uh weighted squats or deadlifts um we're just
00:24:42.200
talking about the leg muscles and you will not bulk up it just it's impossible because if you're doing
00:24:46.920
the work running uh you're still going to be you're still going to be um leaning out that muscle
00:24:53.580
tissue it's just that what we've done is we've worked on your power we haven't worked on your
00:24:57.440
size we've worked on your power right so so it's not an issue bulking up is not an issue and i
00:25:02.680
defy you to show me one you know one cyclist who has complained about uh bulking up because of the
00:25:11.200
work he did in the gym most cyclists you look at their quads even if they're not doing gym work
00:25:16.120
their quads are pretty you know pretty uh big meat slabs because if because of the especially
00:25:22.060
the sprinters because of that work that they do right so nothing you do in the gym is going to
00:25:27.040
um hamper or hinder your your ability to race efficiently it's really about the power to weight
00:25:34.100
ratio that we're developing um cyclists in particular you know they look at this magic
00:25:38.560
number of six watts per kilogram and if you can get the six watts per kilogram over extended periods of
00:25:43.340
time uh you're going to beat the guy next to you uh given uh the same you know equipment and
00:25:49.120
everything else so let's talk about sprinting because that uh is an anaerobic activity um so
00:25:55.200
how does that help you i mean how does this fit in with the idea that you know we want to build an
00:25:59.080
aerobic base uh in our uh endurance uh training right so then sprinting comes in because a couple of
00:26:06.540
reasons um number one uh sprinting is another way to um to work on that uh sustained power that deep
00:26:14.280
power when we talk about sprinting we're not so much talking about the old school of the intervals
00:26:21.120
and if you're a you know if you're a marathoner you probably did a lot of um half mile repeats or mile
00:26:27.020
repeats or really longer intervals that we wouldn't really call sprinting to begin with
00:26:32.260
and it was rare at least when i was training that a that a marathoner would do 100 meter sprints or 200
00:26:38.740
meter sprints because it was like okay how does that that doesn't apply to what i'm doing in the
00:26:44.040
marathon i'm not i'm never running that fast so why should i train that fast well the answer is
00:26:48.160
because uh what we're training is we're first of all we're we're looking at how can we get
00:26:53.240
the most effective workout with the least amount of of pain suffering and sacrifice we call it the med the
00:27:00.580
minimum effective dose so when you're sprinting if i can show you that by doing
00:27:06.020
six to eight sets of 10 to 20 second sprints all out after a warm-up obviously you want to warm up
00:27:14.820
but all out maximum effort and then you're done uh you might go well you're crazy mark how does that
00:27:21.180
help me with a 10k or a or a marathon well what it does is it it works those completely anaerobically
00:27:28.400
which has its own metabolic um side effects that create the gene expression that builds power and
00:27:36.480
strength and speed but it also it's working at the level of the um the structure of the of the tendons
00:27:44.640
the ligaments and the muscles so you're doing a lot of work in a very focused period of time
00:27:50.280
that allows you to spend shall we say less time on the ground and more time in the air if you're a
00:27:58.400
uh more efficient at at pedaling through the entire barrel of the stroke if you're a cyclist
00:28:03.900
and you know what i'm talking about um you know cyclist the idea to become efficient cyclist is to
00:28:10.000
be inside this cylinder that you're always trying to to pedal out of so you're pulling up on the top
00:28:15.380
you're pushing forward in the front you're pushing down on the on the on the downstroke and you're
00:28:19.420
pushing back on the backstroke you know what i mean so you're not just hoping the pedals get over
00:28:23.900
the top and then stomping on them but you're becoming more efficient well all of these things
00:28:27.940
whether you're sprinting as a runner or or as a cyclist and it works for swimming as well
00:28:33.460
that sort of training is now preparing you for uh that efficiency of the actual uh the actual work
00:28:42.940
being done by the muscle itself so not so much in terms of the uh the energy source but in terms of
00:28:50.120
the mechanical force that's being produced by that set of tendons and muscles does that make sense
00:28:56.500
yeah that that makes sense um so i mean i imagine in the book people can find out uh how this all this
00:29:02.200
training works together your period you lay out a periodization a suggested periodization program
00:29:06.480
um in the book and what i love about your book as well is that you know you give prescriptions but
00:29:11.740
it's not overly prescriptive i think the overarching um theme or idea in the book is like you got to just
00:29:16.740
like listen to your body do what works for you i mean my goal here is to make people intuitive about
00:29:22.420
their training and so how we do that or how i elected to do that is through some education this
00:29:28.640
is how the body works this is what's what what we've learned from the science in the past 20 years
00:29:33.300
that we didn't know 20 or 30 years ago here's how we can apply it if we want to but ultimately
00:29:38.100
you are the best coach for yourself and when you understand the ramifications of these choices
00:29:45.580
you're making and you wake up in the morning and you say well how do i feel today i had this plan
00:29:50.620
but if i don't feel like doing it i'm okay uh taking the day off i don't have to feel guilty
00:29:55.720
because i was supposed to go for a you know an easy 15 mile hike today or a easy 50 mile bike ride
00:30:04.120
or whatever but i don't feel like it and i'm i don't feel prepared then great now you become intuitive
00:30:09.960
and wait till you're ready for it and particularly true with a with a with a sprint day for instance if
00:30:15.200
you're not firing on all cylinders on a sprint day don't do it you'll you'll gain more by taking
00:30:20.600
the day off and resting than you will from slogging through a workout that may predispose you to injury
00:30:26.120
or may set you back because your immune system wasn't ready for you to dig that deep that day
00:30:31.560
okay so let's let's go back to nutrition because this ties in uh ties in tightly with uh the training
00:30:37.940
because the goal with uh primal endurance is you want to focus on aerobic training and that requires
00:30:43.620
fat it burns fat as fuel so i imagine the diet we want is to when we're training on the primal
00:30:51.980
endurance way is more fat focused as opposed to carb focused yeah correct it's more healthy fat
00:30:57.560
focused for sure um but we we look at uh you know how do we what are we trying to do here we're trying
00:31:03.300
to force the body to make changes to up regulate gene systems that will build a more powerful set of
00:31:10.120
muscles that will allow us to be able to access stored body fat and burn it more efficiently
00:31:14.520
that means um building more more mitochondria which is where the fats burn within the cells
00:31:19.580
making those mitochondria more efficient all of this happens as a result of gene uh genes turning on or
00:31:26.600
off in response to the signals we give epigenetics this is epigenetics and this is the key to everything
00:31:31.980
we talk about in in primal blueprint and primal endurance and everything primal paleo or ancestral
00:31:37.300
how do we harness the power of our genes through the epigenetic choices we make uh with the foods we
00:31:44.320
eat the types of workouts we choose to do the amount of sun we get the amount of sleep we get the amount
00:31:48.600
of play we we take on well one of the strongest uh sets of epigenetic um regulators is food and
00:31:57.100
the very fact that we could eliminate or cut way back on carbs is a powerful signal to the body that wait a
00:32:06.820
minute i've been i've been relying on carbohydrates my whole life because you've been feeding me every
00:32:11.200
two or three hours and now you change the rules now you're cutting back on the carbs you're not
00:32:15.380
feeding me as often you're feeding more me more fat i guess i have to adapt and so the body up
00:32:21.080
regulates these enzyme systems that are involved in taking fat out of storage it up regulates those
00:32:26.060
enzyme systems that are involved in building more mitochondria the mitochondria have their own dna
00:32:31.020
those mitochondria respond by getting more efficient at burning fat and lo and behold over time by having
00:32:37.500
reduced the sugars and the simple carbohydrates in your diet by having increased the amount of healthy
00:32:43.640
fats and pretty much kept protein steady uh you have reconfigured i say reprogrammed your genes
00:32:51.880
to become a fat burning beast to make you a fat burning beast to make you able to access stored body fat
00:32:57.740
um on a minute to minute basis so that you don't have to rely on carbohydrate at every meal you don't even
00:33:04.920
have to rely on three meals a day most people who are who are in this space right now are doing some form
00:33:10.960
of compressed eating window where they wake up in the morning they're not really that hungry because they're
00:33:15.600
so good at burning fat they're not they're they're literally not having fasted overnight because the body's been
00:33:20.740
taking its energy from stored body fat so you wake up you're not hungry and i say if you're not hungry
00:33:25.800
why do you want to eat uh you know you you're good at burning fat become more efficient at burning fat
00:33:30.700
so a lot of these people who are doing this type of training don't eat until noon or one o'clock it's
00:33:36.480
what we call a compressed eating window or intermittent fasting so they have their first meal at one and
00:33:41.060
then they have their last meal of the day at 7 p.m and starts that cycle all over again but in between
00:33:46.900
in those uh 18 hours in between they're burning a lot of fat and they're training their body to burn fat and
00:33:53.960
that translates directly to how they access fat when they go out and do that aerobic threshold training
00:34:05.460
yeah i love the analogy you made about the book about between carbs and fat
00:34:17.180
but not not very efficient not very clean whereas fat is more like solar power
00:34:22.600
exactly yeah i mean and solar power is unlimited and and you know fats are virtually unlimited i mean i
00:34:29.480
think back to the original premise that we we opened this discussion with which is that for the longest
00:34:34.620
time we thought that that that what determined your success in a race was uh how you manage glycogen but
00:34:42.640
when you realize that the body can only hold about 2 000 calories worth of glycogen uh at any one time
00:34:50.260
and of those 2 000 calories 400 sort of reserved in the liver for the brain that leaves 1600
00:34:57.040
and the muscles will never uh willingly run out of glycogen completely down to zero
00:35:03.860
so maybe you've got you know 1200 calories accessible for this race that you're going to do that's 300 grams
00:35:11.140
total of carbohydrate well your body you can store even on a lean athlete
00:35:16.140
uh you can store 30 or 40 000 calories worth of fat and in some cases more uh and that's enough to
00:35:23.140
to to jog easily 300 miles uh big difference there between the these two uh sources of energy so
00:35:32.040
back to the the more you can become efficient at burning fat the more you can reduce your reliance
00:35:38.120
on carbohydrates and and this glycogen reserve that you have the better you will compete the less
00:35:45.060
sugar you'll put through your system and we didn't even talk about you know the sort of devastating
00:35:49.480
effects of a lifetime of consuming high amounts of sugar right i mean it's terrible i mean like i mean
00:35:56.260
you talk about some of it some of it's just it's fascinating what what the sugar does to our bodies
00:36:00.560
yeah i mean it's it's clear that uh of the 35 million people that are either currently diagnosed
00:36:06.940
or will be diagnosed with type 2 diabetes in this country it's it's that inability to manage large
00:36:12.740
amounts of glucose coming into the body whether it's from sugar or whether it's from uh even sometimes
00:36:17.580
quote-unquote healthy sources of carbohydrates like grains and whole grains or refined grains and
00:36:23.060
things like that so the uh the excess sugar is very toxic to the body the body does has a lot
00:36:30.040
of ways of getting rid of excess sugar which is another kind of red flag when people say well
00:36:37.020
wait a minute glucose is the preferred fuel of the body if it were so why would the body have all these
00:36:41.760
mechanisms to limit the total amount in our bloodstream to uh what amounts to a teaspoonful
00:36:47.420
at any point in time and uh why would it allow us to to store unlimited amounts of this other uh very
00:36:54.620
efficient fuel that we call fat uh too much sugar is inflammatory and that was one of
00:37:00.020
my biggest issues with uh with my uh heyday of my of the training when i was consuming
00:37:06.400
700 to a thousand grams of carbs a day to be able to fuel my 100 miles a week of training
00:37:13.120
uh it turns out that that was very pro-inflammatory the just the pure sugar that was in the drinks and
00:37:19.400
the and the sweet stuff that i was taking in but also in the form of uh the grains that i was consuming
00:37:25.500
i mean i found in my case that i had a big issue with gluten and gluten analogs that exist in other
00:37:32.840
grains to the extent that when i eliminated all the grains from my diet um the the major source of
00:37:39.320
inflammation throughout my body went away and that was life-changing i mean the arthritis that i had in
00:37:44.260
my feet for 30 years that went away the the arthritis that i just recently started to develop in my
00:37:51.660
early 40s in my fingers went away and i thought well that's how could that possibly be that's just
00:37:57.280
normal arthritis isn't it no it was completely related to the foods that i was eating uh so when
00:38:03.540
you see the the immediate effects of uh reduction in pain from from inflammation i mean my ibs went away
00:38:11.200
that was a huge thing for me so all these all these pain elements in my body went away uh that were
00:38:17.680
largely determined by inflammation i started to think in terms of of the the late the latest
00:38:25.060
philosophy in heart disease which is that heart disease is not a factor of of cholesterol and and
00:38:31.600
and saturated fat per se but it's a disease of inflammation uh and it's really the cholesterol
00:38:38.080
that's acting as a band-aid within the um the blood vessels that's that's caused by the inflammation
00:38:44.820
that becomes the issue if you don't have the inflammation then you don't have the issue and i
00:38:49.540
thought i started to think well wow that's maybe all of the stuff that was obvious to me from the
00:38:55.040
inflammation in my fingers the arthritis the ibs um you know maybe i just dodged a bullet here because
00:39:01.520
that same inflammation was happening in my arteries and now it's i can visualize that it's not
00:39:07.280
happening at all because i i i removed those uh inflammatory offending ingredients yeah
00:39:14.480
and it's i mean yeah you're right during i remember like during the it was like during the 80s and 90s
00:39:18.340
the whole cholesterol fat is bad for you and that's when the whole like low fat foods came out
00:39:24.220
and were snack well cakes fat-free margarine and now we're like we have research that's coming out
00:39:30.660
even like the i guess it's what health organization with the government is saying that oh yeah like
00:39:35.700
that's what we said 20 years ago you can ignore that well i wish they'd say that but they don't quite
00:39:41.660
say that they say um you know maybe some of the research on saturated fat isn't as uh overwhelmingly
00:39:48.600
negative as we've been telling you for 40 years so they're slowly backtracking but uh it's still
00:39:54.540
frustrating to see the the guidelines at least by the u.s department of agriculture and the fda and
00:40:00.240
and uh and the departments of health that are clinging to this notion that well we should still limit
00:40:07.100
fats to a very low number and we should still make uh complex carbohydrates the base of our of our food
00:40:13.760
pyramid um yeah it's frustrating but so so the sum up we're what we said your nutrition primarily you
00:40:20.220
want to go fat so we're talking about good fats here we're not talking pending pounding back you
00:40:24.060
know uh state fair corn dogs and waffle that's right we're talking like avocados olive oil state fair
00:40:31.860
corn dogs i like that yeah no we're yeah exactly so we're we're eliminating the industrial seed oils
00:40:36.960
so we're getting rid of soybean corn oil canola for sure and all of these industrial seed oils that
00:40:43.840
have been uh permeating our food supply for the last 40 years so when you buy a processed food which i
00:40:50.540
hope you don't check the packaging uh and if it has any of those offending oils don't buy it but
00:40:56.120
absolutely take in uh avocado oil um coconut oil butter ghee lard um nuts nuts have a lot of fat in it
00:41:06.320
yep yep um uh you know and things like that and then and then um grass-fed animals if you're
00:41:13.580
inclined to get your sources of protein from from uh animals uh either pastured chicken uh you know
00:41:20.500
grass-fed beef uh line caught wild salmon things like that and your carbs should probably be like
00:41:25.060
vegetables we're talking like broccoli sweet potato so you're not saying like i mean you do talk about
00:41:29.520
the book you could go like no carb and go to like a ketosis uh which is even like cleaner than fat
00:41:35.920
but you don't have to do that you could right you don't have to and that's sort of the next level
00:41:40.760
stuff that we talk about the ketosis and i'm giving a talk in a couple weeks on on ketosis and you know
00:41:47.240
how as an athlete you can use ketosis to your advantage uh but it's a it's a commitment uh and i'm not
00:41:53.400
even spending that much time in ketosis even though i'm a big fan of it as a tool for enhancing your
00:41:58.220
ability to burn fat i'm a i'm a fan of cyclic uh ketogenesis which means you go into ketosis for a
00:42:03.260
couple of days or a week then you go out for a while and when you're in ketosis you're giving
00:42:08.020
your body those signals so it's it's improving the efficiency of the mitochondria it's doing a lot of
00:42:12.600
good things and then when you go out of ketosis as long as you don't start cramming down you know
00:42:18.480
sugar and and increasing your carbs dramatically you'll you'll retain that metabolic machinery that you
00:42:23.760
just built so there's a way to i was gonna say have your cake and eat it too but i wouldn't say
00:42:28.500
that um have your olive oil yeah well have your yeah have your um cheesecake or whatever not cheesecake
00:42:36.100
yeah you're you're whatever there's a way there's a way to do this and and get the benefits of uh of
00:42:41.320
all the um the tools of and strategy that we're talking about here you don't have to really commit
00:42:46.000
to being in ketosis uh for long periods of time or for the rest of your life as some people i'm talking
00:42:51.680
to are they're so enamored of it that they're uh they're saying this is you know this is the way to
00:42:56.920
uh a really long life i just to be honest with you i just like to eat such a wide variety of foods
00:43:02.620
that i don't want to eliminate so much from my diet that uh that my uh gustatory pleasure
00:43:09.480
is compensated for gustatory all right um so besides the diet and the nutrition what other lifestyle
00:43:15.860
changes should endurance athletes make to perform better you know with a lot a lot of stuff we talk
00:43:21.660
about the book is um find ways to move throughout the day every every time you're moving throughout
00:43:25.980
the day you're contributing to your aerobic efficiency so if it's um a stand-up desk uh my
00:43:32.100
at my office all my employees have the option to get a treadmill at their stand-up desk if they want
00:43:37.100
uh so some people are putting in eight nine miles a day of easy walking while they're doing their work
00:43:42.740
uh but find ways to move uh take a take a lunch break with with your um work mates uh have a meeting
00:43:51.160
on during a walking session uh there's sort of the new thing among the the we work crowd and the
00:43:56.700
millennials is having uh walking meetings um let's see uh you know i i like um i get a massage once a
00:44:05.220
week uh i'm a big fan of deep tissue massage so i get if i get uh get worked on i get the kinks worked out
00:44:12.120
uh get get sort of actively uh stretched or passively stretched i should say um in that process
00:44:19.700
um i like cold cold therapy so i do a little cryotherapy i have an unheated pool every night
00:44:25.800
before i go to bed i might jump in the pool spend uh two or three minutes cooling down and uh then towel
00:44:32.480
off and go to bed and i sleep like a baby uh sleep is another important part of our ability to perform
00:44:39.280
better we we only perform well when we recover and improve from our workouts and sleep is that time
00:44:45.940
at which the body is doing its its greatest amount of restoration and and repairs so it's critical that
00:44:52.620
anybody intent on improving performance manages sleep to the extent that they're getting
00:44:57.440
seven and a half eight hours minimum per night well mark this has been a fascinating discussion
