00:00If you're really committed to developing your cardiorespiratory fitness,
00:04you know, I think I talked about this on one of the podcasts, maybe it was on Tim's podcast.
00:09You're trying to maximize the area of a triangle, right? So the triangle has a base
00:14and the triangle has a peak. And the goal is how big an area can I get? Not how wide,
00:21not how tall. You don't want one that's this wide and this tall, and you don't want one that's this
00:25tall and this wide. You want the max. The base is your zone two. The peak is your VO2 max.
00:33From a training perspective, the rule of thumb that is applicable for people like us, i.e. normal
00:39people, and the best athletes in the world is roughly 80-20. 80% of your volume is down here,
00:4820% of your volume up here. In fact, some of the really, really elites are probably closer to 90-10.
00:54So you're saying no matter if you're just an ordinary athlete or you're the best of the best,
01:00it's still roughly the same?
01:03Tadi Pogacar, who's the greatest cyclist on this planet, two-time winner of the Tour de France,
01:10you know, absolutely mopping up the field of cyclists like they're children,
01:15that guy's doing 80% to 90% of his training at Zone 2. And I know that for a red fact because we
01:21know who his coach is. So then let's maybe talk about that pyramid. So maybe let's just step back
01:26and say... I didn't answer your question, by the way, about VO2 max, which we can come to, but...
01:29Yeah. So maybe I was just going to say, maybe let's just cover the whole pyramid. So what's
01:32the training of the whole pyramid? If you know it's kind of 80%, 20%, let's break out what that looks like.
01:36So I just start with how much time am I willing to put into this? Now, I got to be honest with you.
01:40I wish I could be putting 10 hours a week into cardio. I do. I mean, historically, I've put in
01:4714 to 20 hours a week into cardio up until 10 years ago. So like, I really miss those days. I miss
01:54being insanely fit. You know, I miss that terribly. And I miss the joy of that much training.
02:01Um, it's simply not possible today. I, you know, for all of the obligations that I have, and
02:08there's, I've done the math 10 ways to Sunday, I'd have to give up something I'm not willing to give
02:13up. I've had to give up archery or give up driving or give up my kids or something like,
02:19I'm just, I'm not willing to give any of these things up. So yeah, I basically start with what's
02:23the most amount of time I can put into dedicated cardio. And for me, it's like four to five hours a
02:28week, not including rucking. I sort of keep that in its own bucket. So then it's a very simple
02:33calculation. 80% of that time is zone two and 20% of that time is VO2 max. And how are you breaking
02:40out? Let's just start with zone two. How many? I divide it into four workouts a week. So four?
02:47Tuesday, Thursday, Saturday, Sunday. And do you always recommend doing it over? Like,
02:55let's say you could do four hours in one day. Is there the same benefit of doing all your zone
03:01two in one day versus spreading it out? No, I think, you know, I've talked about this
03:05within you go. His view is if you can get at least 30 to 45 minutes, you should spread them out. So
03:11again, if you're only able to commit an hour to it, it might be one hour once or 30 minutes twice.
03:17Um, but I'm sort of doing 45 to 45 minutes to 60 minutes each time is what I do.
03:26And are you doing zone two VO2 max on the same day?
03:31One of those days. So Saturday, uh, sort of Tuesday, Thursday is just zone two, uh, and then
03:39two long sessions of, uh, stability training. So it's like, call it an hour of zone two,
03:46an hour of stability. Actually, why don't I just walk you through the whole week? That'll be
03:49easier. So Monday is just strength training. So that's about, uh, 90 minutes to two hours when
03:56you include the stability training that I do as well. So movement prep, stability training,
03:59strength training, and that's all lower body. That's Monday. Uh, Tuesday is zone two followed
04:06by dedicated hour of stability. Wednesday is, uh, upper body strength and stability. Again,
04:1590 minutes to two hours. Thursday is a repeat of Tuesday. Friday is a repeat of Monday. Saturday
04:23is zone two in the morning, upper body strength, repeat of Wednesday in the afternoon. Sunday
04:33is zone two followed by VO2 max. And will you ever do VO2 max before you do zone two?
04:41Um, I generally don't just because I like to have a lot of reps before I go for broke. So even when I
04:53was like a cyclist and doing two zone VO2 max workouts a week, they were always preceded by a long,
05:01uh, the metric we would use, um, on a bike was kilojoules. So it was how many kilojoules of work
05:07would you do before you would do the super hard sets? And it had to be at least a thousand kilojoules,
05:12which would translate to at least a thousand calories of work. And for zone two, I know you
05:19said you kind of like to break it up is if someone is like, Hey, you know, I can do four days a week
05:25of zone two, but I can only do 15 minutes a day. Would you say? Then I'd compress it. I would say do
05:31two thirties. So, so in your zone two sessions, you like to do at least 30 at a minimum. Yeah.
05:39And now when you're in those zone twos, are you like when you hit the bike and the clock starts?
05:45No, I take 10 minutes. I'm on, I do it all mine on a bike. Um, sometimes on a treadmill, but what I
05:51do is there's a, like a little, it's a, it's, it's the, the computer is programming to the Wahoo
05:58kicker, which is the device I'm sitting on. So it's, it's taking 10 minutes to ramp me up
06:02and maybe just walk through what modalities can people do zone two on treadmill by anything that
06:10is steady state. So, you know, swimming is a great way to do it because you can really swim in a pool
06:17at a steady state. Um, running is a great way to do it because you can pretty much run at a steady
06:22state. Cycling outdoors is generally hard. Um, unless you have specific, like Fiesta Island was
06:30a great place to train. I used to train at Fiesta Island because for people who don't know where that
06:34is in San Diego, it's where all with a time trial bike races were, and it's just a seven kilometer
06:39loop that you can ride on without lights or any, like there's no traffic or anything that gets in
06:44your way. But for the most part, like I wouldn't be able to do zone two outside here in Austin.
06:49It's just, it's too hilly and there's too much traffic and it just, it, it's, it's, it's fits
06:56and starts. I can do my VO two max here because I go to a hill and that's my favorite way to do VO two
07:01max is on a hill that's about a mile long and just do very hard up the hill and then easy down the hill.
07:08But, um, a treadmill is another great way to do it. Just kind of a walking incline typically
07:14rowing machine. If you're really a good rower, um, you have to be efficient enough. Most people
07:22are not efficient enough and they just, they don't have the strength. They don't have the
07:26stability to row really well for 45 minutes. Stair climber is another really good one. Um,
07:33but you know, it depends again, if you're, if you're starting out brisk walking is probably
07:40good enough too. Yeah. And we, we don't have to get into all the reasons of the benefits of zone
07:46two, because we have so many podcasts with Inigo, San Milan, people can listen to, but you kind of
07:52hinted at another thing there, which is, you know, when you start your zone two workouts, you'll ramp up.
07:57But also a lot of times we get questions where, you know, Hey, I did a 90 minute workout and I was
08:04in zone two for 45 minutes of it. Is that, am I good? No. I mean, what I think what you mean in
08:11that question is, you know, like I went out for a three hour bike ride today. And, um, when I got
08:17back, my computer told me I was in, I did 44 minutes of zone two. So two issues there. One is that's just a
08:22zone two based on heart rate. That's generally the worst approximation of zone two. So zone two
08:27two really is more based on lactate. If we're going to be purely accurate or at a minimum, um, RPE.
08:33But even if you posit that, that 45 minutes of zone two from your heart rate is roughly accurate,
08:40it's not the same physiologically. Cause usually you're passing in and out of zone two in that
08:44situation. And so you're not getting kind of that constant steady state churn, which you're looking
08:50for. What we're really kind of looking for is the harnessing of mitochondrial efficiency.
08:54And to do that, you just, you have to be able to push oxidative phosphorylation right
09:00to its limit before you trip into glycolysis. And you're just, you're at the limit of that
09:07glycolysis being the dominant energy source. Whereas if you're on that ride, you're going
09:12into and out of glycolysis constantly. So it's not that you're so much in zone two for 45 minutes
09:17is that you passed through zone two for a sum total of 45 minutes, which again, that's the
09:23still, there's still value in that, but not for what we're talking about.
09:27Yeah. And what about VO two max? What modalities can you do VO two max training on?
09:33Uh, you know, here, I think it's, it's probably easier in a way, right? Because it's pretty much
09:37anything that gets your heart rate up and gets you very tired. Um, so, you know, look, it could be, uh,
09:44uh, you know, an air bike, it could be a regular bike. It could be a stationary bike,
09:49stair climber, treadmill running outside, you know, the sky's almost the limit. You know, it's,
09:56it's hard to do it on, you know, it's hard, it would be hard to do it.
10:01I'm trying to think, I mean, heck, you could probably do it with something like burpees is
10:06probably pretty tough. Once you get into something that intense, like jumping, because the sweet spot
10:12for VO two max is kind of three to eight minute intervals. So you don't want to be doing things
10:17that are so intense that you can't do them for at least three minutes. Um, and, and so that's why
10:23I'd kind of hold off on that stuff. I mean, when I was young and I was really fit, I did, I did a lot
10:29of it with jumping, but like those, I mean, I can't jump for three minutes anymore. Like I don't have,
10:35it's just that, you know, I'm not that fit anymore. So I have to rely on easier things.
10:40And so what's your, what's your current VO two max workout? So you mentioned kind of
10:44three to eight minutes on, is it typically I do four on four off is sort of where I spend most of
10:51my time, sometimes three on three off on a rowing machine. Um, I got into that quite a bit last
10:57summer, but these days, um, and sometimes by the way, I just am in a bit of a rush and I'll just do
11:04one minute on two minute off at a much higher intensity on the stair climber. So I have one
11:12of those like industrial grade strength climbers. And sometimes I'll just go sprint for a minute up
11:18the stairs. And then it takes me two minutes to get my heart rate back down to about a hundred
11:23and then repeat that for 20 to 30 minutes. So that's kind of like my poor man's cheating VO two max
11:30workout. Um, but what I really like to do is four minute repeats, four minutes on four minutes off.
11:36And on the four minutes on, are you going a hundred percent for the full, like how,
11:41how should someone think about? Yeah, this is one of those things you have to,
11:44you have to play with this. There's a, this is years and years of practice to know what that feels
11:49like. Um, so again, I'm doing this on a bike. So I'm looking at wattage and, um, my Watts are so low
11:55now I'm embarrassed. I'm not going to tell you what the Watts are because there's so much lower than
11:59they used to be, but I know I have a sense of what I need to average my wattage over those four
12:05minutes. So I might go out at 105% of that wattage and it feels pretty easy for the first minute.
12:16If it doesn't, I've gone too hard by three minutes. I'm very uncomfortable. And at a minute,
12:25I'm, I mean, with that, in that last minute, IE at four minutes, I'm, I don't have much left.
12:33So that's, you know, if you go out all out in that first minute, you're not going to get to
12:38four minutes. You're, you're just going to crash and you're, you're sort of not in that zone. You
12:42want to, so it's not, there's no question. I positive split the thing, meaning I do more work
12:47in the first half than the second, but I don't want it to be more than about 10%.
