Welcome to Huberman Lab Essentials,

0:02

where we revisit past episodes for the

0:04

most potent and actionable science-based

0:06

tools for mental health, physical

0:08

health, and performance.

0:11

I'm Andrew Huberman and I'm a professor

0:13

of neurobiology and opthalmology at

0:15

Stanford School of Medicine. And now for

0:18

my discussion with Jeff Cavalier. Jeff,

0:21

such a pleasure for me to have you here.

0:23

>> I'm glad to be here. It's amazing.

0:25

>> I'm a longtime consumer of your content.

0:28

I've learned a tremendous amount about

0:31

fitness, both in the weight room,

0:33

cardio, nutrition, things that I've

0:35

applied for over a decade. One of your

0:38

mantras is uh you know, if you want to

0:40

look like an athlete, train like an

0:41

athlete. And I think that's something

0:42

really special that sets aside what you

0:45

do from what a lot of other um very

0:48

well-qualified people do. What's the

0:50

sort of contour of a basic program that

0:53

anybody could think about as a starting

0:55

place? I I think it's like a 6040 split

0:58

which would be leaning towards uh weight

1:00

training you know strength and and and

1:02

uh and then you know the conditioning

1:04

aspect be about 40%. So if you look at

1:06

it over the course of a training week, I

1:08

mean five days in a gym would be a great

1:10

task. And obviously not in the gym, it

1:12

could be done at home, but three days

1:13

strength training Monday, Wednesday,

1:15

Friday, conditioning, Tuesday, Thursday,

1:17

you know, two days. It's a it's a pretty

1:19

easy roundabout way to split that up. Of

1:22

course, depending upon training goals

1:23

and as you said, the aesthetic goals

1:25

like that will shift dramatically. But

1:27

if you want to see the benefits of both,

1:30

that's probably the the effective dose

1:32

for strength training and the effective

1:33

dose for conditioning at the bare

1:35

minimum level. If we try to keep our

1:36

workouts to an hour or less, if

1:38

possible, now depending upon the split

1:40

that you're following, if you're on a

1:41

total body split, there's just going to

1:43

be more that has to be done in a given

1:45

amount of time. But in general, when

1:47

you're not focused on that one aspect,

1:49

but the overall health picture, then you

1:52

can get the job done in in under in

1:54

under an hour. And again, I always say

1:56

on top of if if you want to look like an

1:57

athlete, train like an athlete, is you

1:59

can either train long or you can train

2:00

hard, but you can't do both. As you

2:02

start to get older, it's the length of

2:04

the workout that actually causes more

2:07

problems than the intensity of what

2:08

you're doing. Particularly if you're

2:10

warmed up properly, like you said, I

2:12

found personally that my warm-up has had

2:14

to become more of an integral part of my

2:15

my workout than it ever has before. In

2:18

terms of splits, you mentioned splits.

2:19

And so for those who aren't familiar

2:21

with this uh term splits, it's really uh

2:23

which body parts are you training on

2:25

which days. I've seen you discuss, you

2:28

know, three days a week, whole body

2:30

workouts. I've heard of splits like a

2:32

pushing one day, uh pulling another day,

2:35

legs another day, a day off, repeat. I

2:37

mean, there's so many variations on

2:38

this. What's governing the the split? Uh

2:41

>> for me, the first rule is will you stick

2:43

to it? I don't particularly like full

2:45

body splits. I don't necessarily like to

2:48

have to train everything. Now, of

2:50

course, the volumes will come down per

2:51

muscle group. But if you don't like to

2:54

do that and you actually don't look

2:56

forward to your workout because you're

2:57

dreading having to do everything and

2:58

feeling maybe too fatigued by the time

3:00

your workout's over or the fact that

3:02

those generally do take a little bit

3:04

longer and don't fit into your schedule,

3:05

I don't care how effective the split is.

3:07

A split not done is not effective. So,

3:10

you need to find one that fits. So maybe

3:11

you go into an alternative option like a

3:14

um a push pull legs like you mentioned.

3:16

That could be done either one cycle

3:18

through the week on a Monday, Wednesday,

3:19

Friday split or it could be twice in a

3:21

week. So you're actually training six

3:23

times, you know, where where you repeat

3:25

it. You know, pull push legs, pull push

3:26

legs or or you know, uh you know,

3:28

however you want to do it with either a

3:30

day off in between the three days or at

3:32

the end of the six days. Um and again,

3:34

that actually impacts your schedule.

3:36

I've broken that down before where it's,

3:38

you know, if you put it in between the

3:39

three days, it's good because you're

3:41

giving yourself an extra rest day in

3:42

between, but it starts to shift that day

3:44

off every week as we wrap around. So,

3:46

for those guys that were choosing that

3:48

seven-day schedule out of convenience in

3:49

our heads, you know, it starts to mess

3:51

with that off day. So, others like to

3:53

just keep it predictably, let's say on a

3:54

Sunday and train six days in a row. Um,

3:57

but that's a but that's a a better way

3:59

to maybe group similar muscle actions

4:03

together, which I think I I definitely

4:05

prefer that because if I'm going to be

4:07

training, you know, pulling movements,

4:09

at least there there's a synergy between

4:11

them and I feel like I'm looking to

4:14

achieve one goal that day. Um, and then

4:17

I mean quite honestly, you can go back

4:19

to the bros split days and those those

4:22

still work effectively. There's a reason

4:23

why they worked in the past. Like I

4:26

think that science shows that there's

4:27

smarter ways to do them these days. Like

4:29

you can you can come back and hit a

4:32

related muscle. So you could do let's

4:33

say biceps on one day and then come back

4:36

two days later and do back realizing

4:38

again synergy between the the exercises

4:41

there. Your biceps are going to get

4:42

reimulated again. So you could figure

4:44

out ways to make that work. But the

4:46

thing that I think is is effective there

4:47

is that tends to be one of the ones that

4:49

people like the most because they can go

4:51

in, they get their pump, they feel good

4:53

that it's it's pretty solely focused on

4:55

one muscle group.

4:56

>> Is that the definition of a bro split?

4:58

One

4:59

>> one muscle group a day. Yeah.

5:00

>> I see. So it's very much geared towards

5:02

strength and aesthetics. Really

5:03

maximizing chest.

5:05

>> Probably probably more more aesthetics

5:06

than strength. Yeah. in terms of the

5:10

mixing up of cardiovascular training and

5:14

resistance training. Um, same day,

5:16

different day, which one should come

5:18

first, which one should come second? So,

5:21

again, I I I think that the, you know,

5:22

the bare minimum is probably twice a

5:24

week in terms of cardiovascular if you

5:26

want to have some semblance of

5:27

cardiovascular conditioning, but I think

5:29

most people who actually need it more or

5:31

want to pursue it more than that are

5:33

going to need more time to do that. So,

5:36

um, at some point it can't just be

5:37

relegated to a day off or a day off from

5:40

the from the weight training workouts.

5:42

So, at some point it has to occur on the

5:44

same day, you know, and in that case I

5:46

just like to put it at the end of the

5:48

workout because you don't want to in any

5:49

way compromise the weight training

5:51

workout. The intensity of those workouts

5:53

is important. I just like to, you know,

5:55

put that at at the end realizing that

5:58

even if my effort level is lower or my

6:02

output is lower, if it's still placing a

6:04

demand on my cardiac output to get that

6:08

conditioning effect because I'm

6:09

fatigued, it still has a demand on my

6:11

cardiac output. So, it's still achieving

6:13

its goal, but it didn't interfere with

6:15

my main goal of being able to increase

6:17

my performance in the gym. And in terms

6:18

of the form of cardiovascular training,

6:20

I've seen you um do a number of I have

6:24

to say very impressive high-intensity

6:26

interval type work rather than uh on the

6:29

treadmill or out jogging for 30 45

6:31

minutes. Is that because you prefer

6:33

higher intensity um higher heart rate

6:35

type um training? If if we could blend

6:39

function across these realms and not

6:42

have such a delineation between this is

6:44

my weight training and this is my

6:46

conditioning but figure out a way to to

6:48

blend them together. I always think that

6:50

you've get you've got a better

6:51

opportunity to get that more

6:52

well-rounded result. And I like to kind

6:56

of mix up that straight conditioning

6:58

work and also some of the footwork, you

7:00

know, drills. Like we have we we have

7:01

some high expectations for guys that

7:03

come into our programs like to just do

7:05

some footwork drills

7:06

>> like ladders

7:07

>> like ladders or or line drills or

7:09

something and you know what happens

7:10

people become intrigued and interested

7:12

like I never I haven't tried this since

7:13

uh high school you know and they become

7:17

interested in just the challenge of it

7:18

and as we become almost distracted by

7:20

the challenge we're now like finding

7:22

ourselves conditioning you know and and

7:24

I always think that's an important part

7:26

that sometimes you got to draw people in

7:28

um to get to show them what they might

7:31

be interested in and from the output or

7:33

the effect of it. I just think that when

7:35

you're able to blend some of some, you

7:36

know, still maintain some of that

7:38

strength training into the exercise. So,

7:40

as you mentioned, let's say I'm doing

7:41

some kind of a push-up or a burpee. I

7:43

mean, there is there is a um an anorobic

7:46

component to that that is going to be

7:47

helpful um that then rather than just

7:50

walking or just jogging. Um not to not

7:53

to say that that isn't an effective

7:55

means for strict cardiac conditioning.

7:58

It's a it's one of the ways that we've

8:00

had for, you know, centuries, you know,

8:02

to do it. But I just think that if we

8:04

can blend it, then it becomes maybe a

8:06

little bit more interesting and you get

8:08

some of those crossover benefits and it

8:10

doesn't become so segmented in terms of

8:11

what we're trying to do. One of the most

8:14

important things I learned from you so

8:17

over the years was that if you can flex

8:19

your bicep to the point where it hurts a

8:22

little bit, like it almost feels like a

8:23

cramp or a cramp, or you can flex your

8:24

calf to the point where it really cramps

8:26

up a little bit, almost feels like it's

8:27

nodding up, that's a pretty good

8:29

indication that you're going to be able

8:31

to stimulate that muscle well under load

8:34

if you're doing the movement properly.

8:36

How did you arrive at this kind of cramp

8:37

test, the cavalier test as I'll call it?

8:40

during my workouts, even as a as a young

8:43

kid just starting out, I wanted to know

8:45

what was supposed to be doing the work.

8:48

Once you do that and you start to seek

8:50

that out and say, "Okay, well, if the

8:51

bicep is what's supposed to be doing the

8:53

work, then I want to make sure the

8:54

biceps doing the work, right?" So, I

8:56

would seek out ways to make that happen

8:59

better. And when I was able to do that,

9:01

I could feel the stronger contraction. I

9:03

was no visionary. I just felt like I I

9:05

knew that that was going to be better

9:06

for me if the muscle I was trying to

9:08

grow was being stressed more. When I was

9:11

attempting to do this across different

9:13

exercises, I would notice that what I

9:16

could do potentially on a curl where my

9:18

arm is up, you know, where you asking me

9:20

to flex my bicep, that position I

9:23

couldn't do if I was, you know, doing a

9:25

concentration curl or I couldn't carry

9:27

over to a cable curl. And that shouldn't

9:30

really change, right? Because the

9:32

function is still largely the same.

9:34

there's still elbow flexion, there's

9:35

still supernation. Like, why am I not

9:37

able to do it there? And that's when it

9:39

sort of clued into me that like your

9:41

mind muscle connection on not just your

9:45

mind with one muscle, but on every

9:46

exercise matters and it varies from

9:49

exercise to exercise. There's a term I

9:51

like to call muscularity, you know,

9:53

which is a difference, right? It's the

9:54

level of sort of resting tone in the

9:56

muscle that improves dramatically. You

9:58

know, if you can learn how to just start

10:00

to engage that muscle better, the

10:04

muscularity, the the resting tone of

10:06

that muscle is harder. It's more alive.

10:09

It's all driven from being able to

10:11

connect better neurologically with the

10:12

muscle that you're trying to train. When

10:14

you're trying to go and create muscle

10:16

hypertrophy or even this muscularity

10:17

that I talk about, you need to seek ways

10:20

to make it feel more uncomfortable,

10:21

right? If you don't feel the discomfort,

10:23

then you're doing something wrong. And

10:25

uh I struggle to this day on certain

10:27

muscle groups to still do that even

10:28

knowing what I'm trying to work. It's

10:30

very difficult for some muscles and for

10:32

certain people to do this on certain

10:33

muscles. But as you mentioned, practice

10:36

does help. And the more you become, you

10:39

know, consistent and deliberate with

10:40

what you're trying to do, the more of an

10:42

of a result you actually get. How do you

10:45

assess recovery at the local level,

10:47

meaning at the level of the muscles? So

10:48

we'll talk about soreness and getting

10:50

better, stronger, more repetitions, etc.

10:53

And then at the systemic level, at the

10:54

level of the nervous system,

10:56

>> different muscles recover at different

10:57

rates. You may have a bicep that's able

10:59

to be trained that can be trained again

11:02

the next day, you know, and then the

11:04

next day and then maybe you need a day

11:06

off after that. That can vary from

11:07

person to person for sure and it can

11:09

vary from muscle to muscle in that

11:11

person over the course of time as you

11:13

mentioned because the systemic recovery

11:15

is going to impact all those muscles

11:17

anyway. But let's say you're

11:18

systemically recovering, every muscle

11:20

itself is going to have a recovery rate.

11:22

And I think that using muscle soreness

11:25

as a guideline for that is is one of the

11:28

only tools we have in terms of the local

11:31

level. That's the one that most people

11:32

can relate to and easily identify and

11:34

then use that as a guideline. And if

11:35

you're training when you're really sore,

11:37

um it's probably not a great idea. But

11:39

as far as the the uh the systemic, you

11:42

know, recovery, grip strength is very

11:44

very much tied to performance and

11:47

recovery. And when I was at the Mets, we

11:50

used to actually take grip strength

11:52

measurements as a baseline in spring

11:54

training all the time. Now, obviously,

11:55

as a baseball player, you're gripping a

11:56

bat, your pitcher, you're gripping a

11:58

ball. Like, you know, grip having good

11:59

grip strength is important. So, if we

12:00

notice somebody had a very weak grip,

12:02

it's just a good focal point of a

12:04

specialized training component for their

12:06

>> You do this every day with those guys?

12:07

No, we would do in spring training, we

12:09

do sort of a baseline entry level

12:11

measurement and then we would we would

12:12

measure it throughout the season, maybe

12:14

once every two weeks or three weeks and

12:15

and and you know the idea there was to

12:18

measure the recovery. We have found that

12:20

with one of those scales, those

12:22

old-fashioned bathroom scales, it's a

12:24

great tool for just squeezing the the

12:26

the uh the scale with your hands and

12:28

seeing what type of output you could

12:30

get. Imagine the last time you were sick

12:32

or when you or just try this, you know,

12:33

the next time you wake up in the

12:34

morning. When you first wake up in the

12:35

morning, you're still groggy. Try to

12:37

squeeze your hand. Try to make a fist as

12:39

hard as you can. You're going to sit

12:40

there angry at your fist because it

12:42

won't contract as hard as you know it

12:44

can. You don't have the ability to just

12:47

create the output. And that is because

12:49

in that state, you're still sleepy.

12:51

You're still fatigued. You know, you're

12:53

you're not even awake at the you know,

12:55

the whole level at this point. So, when

12:57

you start to measure that on a daily

12:59

basis, you can get a pretty good sense

13:00

of where you're at. And I think when

13:02

people start to see a drop off of 10% or

13:04

so or or even greater of of their grip

13:07

output, um you really should skip the

13:10

gym that day because I don't think

13:11

there's much you're going to do there

13:13

that's going to be that that beneficial

13:15

even if it is the day to train legs or

13:17

whatever day it is. I mean there

13:18

certainly are more sophisticated tools

13:20

too as a as a PT. You know, we have uh

13:22

uh hand grip dynamometers. You know, we

13:24

can we can measure one side at a time

13:26

table, but that comes at a cost. Those

13:28

are pretty expensive devices. But if

13:29

it's listen, if you were an athlete, you

13:31

know, the the 200 300 bucks it cost to

13:34

have one of those would be well worth,

13:36

you know, the added investment.

13:37

>> When's the best time to stretch for

13:39

particular types of results? And maybe

13:41

you could define some of the different

13:42

types of stretching.

13:44

>> In general, the two basic forms of

13:45

stretching are active stretching and

13:47

passive stretching. And your passive

13:48

stretching is done with the goal of

13:51

trying to create an increase uh in u the

13:55

flexibility of the muscle. So whether

13:57

you're actually increasing the length of

13:58

that muscle, you know, more so what

14:00

you're doing is increasing the resist or

14:02

decreasing the resistance of that muscle

14:03

to want to stay at a certain level of

14:06

flexibility. When we can sort of take

14:08

the brakes off and allow that muscle to

14:10

to allow us more range of motion, we're

14:12

inherently increasing flexibility

14:14

without necessarily having to increase

14:16

the length of that muscle. That is

14:18

usually done at a time far away from

14:20

your workout because there is a period

14:22

of recalibration that is needed after

14:26

doing this because you're disrupting the

14:27

length tension relationship of the

14:29

muscle that causes you to not

14:31

necessarily be able to rely on these

14:34

I've talked about before stored motor

14:36

engrams in your mind in terms of this is

14:38

the pattern for how I swing a golf club

14:40

say you know and now introducing a

14:43

little bit of flexibility or added

14:45

flexibility or range because of the

14:47

stretch stretching I did before. It

14:48

takes maybe a hole or two or three to

14:51

match up again. Oh, this is the this is

14:54

what he's trying to do. That golf swing

14:55

thing that I remembered again. Like it's

14:57

not remembering the every component like

14:59

I have to bend my right wrist back 10°

15:02

and then I have to bend my elbow and I

15:03

have to break like your body stores

15:05

these patterns for motor efficiency. So,

15:07

and when I have to start matching up

15:09

that stored pattern with what's feeling

15:11

new because of the increased range, I

15:13

can impair performance. And again, it

15:15

could happen even in a gym workout where

15:17

you're talking about your first, second

15:18

set, third set, um, where maybe the

15:21

repercussions aren't as big because I'll

15:22

just do a few extra sets. But in

15:24

performance, if you screw up your first

15:25

three rounds, you're playing on a PJ

15:27

tour and you shoot, you know, you're six

15:28

over after three, you're you're you're

15:29

done, you know? So we relegate that as I

15:32

mentioned sort of towards the end of the

15:33

day when it's not going to impact

15:34

performance but even maybe have the

15:36

additional benefit of creating the the

15:40

feeling of length or the increase or

15:42

decrease in resistance to this length um

15:45

at a time when I know my body is going

15:47

to try to tend to heal and heal shorter

15:49

never longer but heal shorter. So if I

15:51

can introduce a little bit of that extra

15:53

uh length or or decrease resistance to

15:55

to that length it's a better time to do

15:57

it. So I think it promotes a a better

16:00

recovery.

16:00

>> I'm intrigued by this concept of heal

16:02

shorter. So part of the healing and

16:04

recovery process means a shortening of

16:05

the muscles. This is the tensing up in

16:07

sleep. Could you elaborate just a bit on

16:09

that?

16:09

>> Basically, you know what what's been

16:10

shown is that when the the repair

16:13

process, muscular repair from, let's

16:15

say, strength training during the day,

16:17

the repair process usually results in a

16:19

muscle that is slightly shorter rather

16:22

than increased in length. you know,

16:23

muscles prefer to sort of ratchet their

16:25

way down into that that uh contraction.

16:28

So, when you're sleeping, it it tends to

16:31

air on the side of shorter rather than

16:33

longer when ideally, we don't really

16:34

want that. We want to maintain as much

16:37

of that length because with more length,

16:39

we actually have more leverage. So,

16:41

again, it's just making a a conscious

16:43

choice to do it at a time of the day

16:44

that makes a little bit more sense.

16:46

Dynamic stretching is really not done

16:48

for that purpose of trying to create any

16:51

type of increasing the the potential

16:53

length as you said of the muscle, but

16:55

more so the readiness of the muscle to

16:56

perform and increasing, you know,

16:59

exploring the ends of that range of

17:01

motion in a more dynamic way. So you're

17:03

not hanging out there and disrupting

17:05

that length tension relationship, but

17:07

just sort of touching the ends of those

17:09

barriers so that when you feel movement

17:12

again, it feels looser, it feels more

17:14

ready. and and obviously at the same

17:16

time warming up, blood flow, all the

17:18

benefits we get from just warming up in

17:20

general. So like you know that's that's

17:22

a series you've probably seen a bunch of

17:24

times but like you know leg swings and

17:27

butt kicks and you know lunge walking

17:29

lunges and those are the drills that

17:31

people will do prior to training that

17:33

are both excitatory in terms of just the

17:35

nervous system but also helpful for just

17:38

the general warm-up of the body because

17:40

the blood flow but from a muscle

17:41

readiness standpoint not impairing the

17:45

performance while at the same time

17:46

exploring the increased ranges. When I

17:49

was working with Antonio Brown, I

17:50

remember like he would spend 20 minutes,

17:53

30 minutes on all dynamic work. And I've

17:55

never seen anybody spend that long on

17:57

their dynamic work, but like he said he

18:00

just didn't feel right and ready to go

18:03

unless he did a lot of that. And I mean,

18:06

you know, his his dynamic stretching

18:08

routine would be a workout for most

18:09

everybody. There's one exercise and one

18:12

particular motion that I'd like to um

18:14

discuss for a moment because I believe

18:17

that learning about this cautionary note

18:20

from you is one of the reasons that I've

18:24

maintained steady training for 30 years

18:26

with no major injury. Uh knock on wood.

18:29

Um and that's the upright row. I learned

18:31

from you that the upright road

18:33

compromises uh some important aspects of

18:36

our shoulder mechanics and could be

18:38

actually sort of a dangerous movement in

18:40

some ways. But so I've always made it a

18:42

point now on the basis of of this advice

18:45

to really strive for um external

18:48

rotation. M

18:49

>> please tell us about internal external

18:51

rotation. Why this is so important not

18:53

just for weight training but as in terms

18:56

of posture and mechanics and and not

18:59

looking like a a melted candle or

19:01

partially melted candle.

19:02

>> The shoulder has the most mobility in

19:04

the body of any of any joint, but it's

19:07

also got the least stability, right?

19:08

There's always that trade-off of

19:09

mobility and stability. So your

19:12

stability comes from, you know, certain

19:16

muscle groups. And one of the ones that

19:17

the only muscle group that actually

19:19

externally rotates the shoulder is going

19:21

to be the rotator cuff. Okay? And unless

19:23

you are devoted to training through

19:25

external rotation and exercises that are

19:28

going to externally rotate the shoulder,

19:30

you're not training that function. And

19:33

it's so easy for us in everyday life,

19:36

especially those that aren't training,

19:37

to not ever really undergo any of those

19:40

stresses that could be beneficial to

19:41

counteracting what happens freely and

19:44

naturally, which is internal rotation.

19:46

So when you think about the imbalance

19:47

created just by nature and how we live

19:49

our lives, internal rotation far far far

19:53

outweighs external rotation. So you need

19:55

to address it. And the reason why you

19:57

need to address it is because you need

19:58

to normalize those biomechanics of the

20:01

shoulder if you want their long-term

20:02

health. And one of the functions of the

20:04

shoulder is to raise our arm up over our

20:06

head. And if we do that from an

20:08

internally rotated position, we're going

20:10

to have a higher likelihood of creating

20:13

stress inside that joint. in order to

20:15

get normal mechanics and free up the

20:18

joint maximally inside, you need to

20:20

externally rotate as you raise the arm

20:22

up. So, if your muscles aren't firing

20:24

and they're not necessarily um as strong

20:28

as the internal rotation bias that pulls

20:30

them in, you're asking for trouble every

20:32

time you do that. Well, this exercise is

20:36

literally putting you in elevation in

20:38

internal rotation. And if you were to

20:39

walk into a PT office and someone said,

20:41

"I think he's got an impingement. Will

20:43

you diagnose him?" There's a test called

20:44

a Hawkins Kennedy test. And I would put

20:46

you in the position, I know we're not

20:48

visible at this point through the

20:49

podcast, but I'll put you in this

20:51

position here where I have your arm

20:53

elevated and your hand pretty much under

20:55

your chin, pushing downward on that to

20:57

create that internal shoulder rotation.

20:59

Pretty much the exact position that

21:00

we're in when we're holding a bar in in

21:02

an upright row. Some will say, "Well,

21:04

just don't go so high. Go only up to the

21:06

level of the chest." But you're still in

21:08

this internally rotated position. The

21:10

the thing that I think frustrates me the

21:12

most about the exercise is that I have

21:14

an alternative. And the alternative does

21:16

the same thing in terms of helping the

21:18

muscles grow by simply fixing the

21:20

biomechanics of the exercise, but just

21:22

allowing the hands to go higher than the

21:23

elbows. So instead of the elbows being

21:25

higher than the hand, which drives you

21:27

into internal rotation, if the elbow is

21:29

lower than the hand, the hand being

21:31

higher here, I'm in external rotation.

21:33

And I could do something called a high

21:35

pull and still get the same abduction of

21:38

the arm and still get the same benefits

21:40

of the shoulders, the delts, and the

21:41

traps without having to undergo any of

21:43

the stresses that would come from the

21:45

somewhat awkward movement of an upright

21:47

row. And people will argue, this is the

21:49

way they argue, that I've done this for

21:51

30 years and I've never hurt myself. And

21:53

I always say yet,

21:56

like listen, the goal is to not hurt

21:59

yourself ever. So even if you it's sort

22:02

of like you know the championship game

22:05

you know you might play the game of your

22:06

life but if you lose you lost and when

22:08

you get into the end of the you know the

22:10

record books you still lost. So even if

22:12

you had the game in your life you lost I

22:14

don't care if you do it for 30 years no

22:15

pain you're still doing it and there's

22:16

no pain. I'm giving you an option that's

22:19

going to give you the same results in

22:21

the exercise that you're seeking. That's

22:22

why you're doing the exercise without

22:24

the the possibility of having the you

22:26

know the bad outcome come from it. The

22:28

body is like a mirror image. The hip is

22:30

like the shoulder, right? The ankle is

22:32

the wrist. The foot is the hand. Like

22:34

they're they they fun. The knee is the

22:36

elbow. They're two hinge joints. They

22:37

function that way. Well, with the

22:39

shoulder, you've got that mobility that

22:41

comes from having all that freedom of

22:43

motion, but the stability is lacking.

22:45

Well, the same thing with the hip. like

22:47

you've got mobility, but if you don't

22:49

fully stabilize it by training all the

22:51

muscles of the hip and if you don't

22:53

strengthen the external rotation of the

22:55

hip, then you know you've you're you're

22:58

going to have issues like it's not

23:00

biomechanically going to work the same

23:01

way. If you think of the body as a

23:03

series of, you know, bands, you know,

23:06

pulling in different directions at

23:07

different levels of tension, you know,

23:09

you're being pulled into one direction

23:11

or the other just by the balance of

23:13

tension from one weak area to one

23:16

dominantly tight area. And you need to

23:19

make sure that you can sort of balance

23:20

this out in order to eliminate some of

23:22

the adaptations and compensations that

23:24

happen. One of the great uh tools that I

23:27

I picked up from your content which has

23:29

benefited uh I know a huge number of

23:31

people is I think I used to hold uh

23:33

weights sometimes in the in the tips of

23:35

my fingers as opposed to in the meat of

23:36

the palm of my hands and I had elbow

23:38

pain. Turns out toward the end of my

23:40

pull-ups or my bicep work I was letting

23:42

the weight or the bar drift into my

23:44

fingertips. and the mere um shift to

23:47

making sure that my knuckles were well

23:49

over the bar or that the weight was

23:50

really in the meat of my palms has

23:53

completely ameliated that for reasons

23:55

that you point out and maybe you could

23:57

just share with us why that is. When you

23:59

grip a bar, whether it be through a curl

24:01

or whether it be and this is mostly

24:03

pulling exercises because the tendency

24:05

for the bar is going to be to fall out

24:07

of your hand, not like with a pushing

24:09

exercise where it's kind of you you're

24:10

pushing your hand into the bar. So on a

24:12

bench press say um that bar can drift

24:16

just by gravity doing doing its thing or

24:19

fatigue of the the hand grip strength

24:22

can start to drift further away towards

24:24

the the distal digits right through

24:26

those through those last couple knuckles

24:28

that we have on our hands though our

24:30

hand can still hold it there the muscles

24:33

are not equipped to handle those types

24:35

of loads and it could start at dumbbell

24:37

weight you know 40 lb 30 lb you know

24:41

even 25 pounds for some depending upon

24:42

their overall strength levels. But then

24:44

when you start to apply it to something

24:45

like your body weight with a chin up,

24:49

right? Because that's natural for the

24:50

bar to somewhat kind of float down

24:52

towards your fingertips. And it actually

24:55

is a little bit easier to perform the

24:57

exercise with that sort of like false

24:59

grip, like a little hook grip at the end

25:01

because you're not going to engage the

25:03

forearms into the exercise. You're not

25:05

going to start pulling down.

25:07

But at the same time, while it could

25:09

help you to perform them better by

25:11

getting the back more activated, if you

25:13

have weakness in these muscles, because

25:15

it's not it's not a thing that happens

25:16

to every this not one of those upright

25:18

row type things where I think this is h

25:20

happening to everybody. This is

25:21

happening to people that have these

25:22

inherent weaknesses in in the these

25:24

muscles. You or or haven't done enough

25:26

of the gripping in the for in the meat

25:29

of the hand, you know, for long enough.

25:31

But it starts to put that stress on

25:34

these muscles that are illquipped to do

25:36

this and it to handle this and it starts

25:38

to particularly on that fourth finger

25:41

you know which is part of the muscle we

25:42

call the FDS of flexor digitorum that is

25:46

just too much for it to handle and that

25:47

comes all the way down and meets right

25:49

at the medial elbow right on that spot

25:51

that you can say feels like someone's

25:52

knifing you right in the middle in that

25:54

medal elbow and and medial epicondilitis

25:56

or they call it golfer's elbow is

25:58

something that a lot of us deal with in

26:01

in the gym. It's one of the most common

26:02

inflammatory conditions people get from

26:04

the gym. And it all comes from this

26:07

positioning of the dumbbell or barbell

26:10

or hand on a pull-up bar over time. So,

26:12

the easiest thing to do is just grip

26:15

deeper so that what you're doing is

26:16

you're using, you know, more leverage

26:18

from the palm to encapsulate the bar or

26:21

the dumbbell or whatever. and you're not

26:23

putting that pressure really distally

26:25

right on that last digit because that's

26:28

where the that FDS muscle is most

26:30

strained. So you you're just almost

26:33

eliminating that from the equation. and

26:35

and and it's one of those exercises that

26:38

the load can exceed its capacity pretty

26:40

quickly. So that like, you know, maybe

26:42

it's only capable of handling 30 lb and

26:45

then when you're doing a chin-up and it

26:46

goes and it drifts so far that it's now

26:49

you, let's say you're a 200lb guy,

26:51

you've got, let's say, 100 lb through

26:53

one arm and 100 lb. This is simple

26:55

simplified math that obviously is offset

26:57

by other muscles, but 100 lb through one

26:58

arm, 100 lbs to the other. 100 lbs off

27:01

of a muscle that can handle 30, it's not

27:03

going to take many repetitions to strain

27:04

it. and you're going to feel that maybe

27:06

by the time that sets over or certainly

27:08

by the time that workout's over or the

27:10

next day you wake up and you've got that

27:11

notable stabbing pain. Whenever someone

27:14

feels that, the best thing would be to

27:16

determine, okay, what exercises would I

27:18

do that were pulling and where the bar

27:20

could have drifted deeper into further

27:23

from the meat of my palm into my fingers

27:26

and figure out a way to deepen that

27:27

grip. When that happens though, the best

27:29

thing to do with most of these

27:31

inflammatory conditions is not do any of

27:33

that stuff for a little while. There's

27:35

so many other options that you can do

27:37

that will train similar muscles or even

27:39

the same motion and not cause that

27:40

stress. So, I mean, a cable curl would

27:43

be much easier to do that on than, let's

27:45

say, a chin-up where you don't have the

27:47

control over the weight like you do by

27:49

moving a pin on a stack. I do have a

27:51

question about precision of

27:53

recordkeeping. Do you keep a training

27:55

journal? Uh, do you recommend people

27:57

keep training journals? I think that

28:00

anything you can do to increase your

28:01

awareness of your performance and also

28:04

give yourself some objective goal.

28:07

Whenever we have an objective goal, it's

28:08

a lot easier to actually obtain it. When

28:10

you're just there to get a pump and

28:12

you're just there to lift how you feel

28:14

that day, um you have to be incredibly

28:17

disciplined in all other aspects of your

28:19

workout in order to make that effective.

28:21

Anything you can do to increase your

28:23

awareness of it and keep you on track

28:24

with that is like I'm endorsing fully.

28:27

Maybe we could talk about principles

28:28

around nutrition. What tends to work?

28:31

What tends not to work? And um yeah, how

28:33

should we think about nutrition?

28:35

>> My approach is like I've always been

28:36

sort of a low sugar

28:38

lower fat guy. That is the best approach

28:41

for I believe again in my opinion

28:44

personally for the overall big picture

28:47

because though the people can take

28:49

exclusionary approaches to nutrition and

28:51

taking carbs out or you know you know

28:54

eating only fats and proteins or again

28:57

I'm not saying it doesn't work for you

28:58

and if it's the first thing that

28:59

actually allowed you to gain control of

29:01

your nutrition to the point where you

29:02

actually saw results and got to a

29:03

healthier weight then I always say then

29:05

do it. then do it. But just make sure

29:07

it's something you can do forever and

29:08

doesn't bring upon other repercussions.

29:11

I think that non-exclusionary approaches

29:14

to diets are the the most sustainable

29:17

for the rest of your life. And when I

29:19

and all I'm interested in from a

29:20

nutrition standpoint is something that's

29:22

sustainable in terms of what you do eat.

29:24

How do you structure that? Um, in terms

29:26

of when you look down at a plate, you've

29:28

done these, you described this before,

29:30

but I think it's just a beautifully

29:31

simple description because I think a lot

29:33

of people don't want to do calorie

29:34

counting and all this. And

29:35

>> I have what I like what I call a plate

29:37

method. And it's just it's just simple

29:38

because it works for me. When you have

29:40

your plate, you just simply look at it

29:42

as like a like a clock, right? And um if

29:46

you just make a 920 on the clock, so one

29:50

arm goes over to the nine and one of the

29:52

arms goes over to 20. because you know

29:54

you're going to make a line towards

29:55

12:00 too. And the largest portion is

29:57

going to be your fibrous carbohydrates.

29:59

So that's the the the you know the green

30:02

vegetables, right? So whether it be

30:03

broccoli or Brussels sprouts or

30:05

asparagus, those are the ones that give

30:07

us a lot of the micronutrients we need.

30:09

They're the ones that are generally you

30:10

know accepted as more healthy. Um and

30:13

they're also going to provide the fiber

30:15

that's going to be both beneficial in

30:16

terms of its uh impact on insulin and

30:18

also just through filling you up, right?

30:21

And then I take the next largest portion

30:24

of that and I devote that towards

30:26

protein. And I think it's really

30:27

important especially for anybody active.

30:29

Um the more active you are, the more you

30:31

embark on trying to build muscle, you're

30:33

going to need to have protein in every

30:35

meal. So I have that. And again, you

30:37

know, we're talking cleaner sources of

30:39

protein, but like I I am you'll never

30:41

find like boiled chicken on my plate.

30:43

I'll have some sort of fish or chicken

30:45

or but I they'll it will be it will be

30:47

cooked in a way that's that's like, you

30:49

know, it's got maybe some sauce on it or

30:51

it's got some maybe it's tomato sauce,

30:53

anything to just make it a little bit

30:54

more palatable and interesting without

30:55

blowing the value of the meal. And then

30:57

that last portion is where I put my

30:59

starchy carbohydrates. And again, that's

31:01

the part that some people will say

31:02

exclude them entirely because they're

31:03

not healthy or they don't work for you

31:05

or they're not, you know, beneficial

31:06

long term. For me, like most people, my

31:10

body craves those carbohydrates. I

31:12

choose things like sweet potatoes, which

31:14

is my favorite, you know, or I'll have

31:16

um rice or I'll have pasta. I will have

31:19

those things. I'm not excluding them,

31:20

but I don't put them in the portions

31:22

that you would generally find. No plan

31:24

is going to work if you're eating stuff

31:25

you don't like. It's not going to work

31:26

forever. Nothing will. You have to

31:28

really enjoy what you're eating. As long

31:30

as these these uh variations of this

31:33

meal are something that you really enjoy

31:35

and there are limited versions of them,

31:38

the reproducibility of that is simple.

31:40

If everyone listening to this podcast

31:42

can figure out their nutrition issues,

31:44

this whole world will be different. That

31:45

is like one of the largest sources of

31:48

disease and and pain and discomfort

31:50

because people really struggle with

31:51

nutrition. What are your thoughts in

31:53

terms of the the nutrition science, the

31:55

train the training related effects of um

31:58

the post-training meal? Is it something

32:00

you think people should pay attention

32:01

to? I'm not very dogmatic about what

32:04

specifically to eat pre or post, you

32:07

know, workout, but I do think you should

32:09

have protein um surrounding your your

32:12

training, whether that be ahead of time

32:14

or after. Protein could be a little bit

32:16

hard to digest for some people. So, if

32:19

you do that pre-workout and then you're

32:20

finding your workouts slogging because

32:22

you don't feel good, then certainly you

32:24

put that after your meal. But this whole

32:27

concept of the urgency of time has

32:29

thankfully been removed and we can just

32:32

learn to eat a little bit more uh you

32:35

know responsibly. And even as far as

32:37

pre-workout supplements, a lot of people

32:39

don't take them. A lot of people don't

32:40

like them. They don't take them. They

32:41

don't like they're not necessarily even

32:43

being used as the nutritive side of the

32:46

pre-workout. They're just more used to

32:49

fuel the workout. Um

32:51

>> for me it's water and um some form of

32:54

caffeine.

32:54

>> Yeah. I mean it's whatever you know

32:56

again I think it's important I do think

32:58

it's important to maintain a high level

32:59

of output. So if your pre-workout

33:02

nutrition requires a stimulant in order

33:04

to help you do that or if your

33:06

pre-workout nutrition is causing you to

33:09

have a harder time to train because

33:10

you're feeling full or stomach ache or

33:13

something else then then that that's not

33:14

achieving what you're trying to do. The

33:16

ultimate goal is to still be able to

33:17

perform at the highest level. So,

33:19

whatever your nutrition is required to

33:21

allow you to still do that, that is

33:23

probably the most important factor of

33:24

all of it. I hate to say, but it's a lot

33:26

less scientific than we want to make it.

33:29

And as it seems to be, coming back often

33:32

times like the thing that works for you

33:34

is really the most important thing

33:35

because ultimately getting your ass in

33:37

there and doing what you do is is really

33:38

the thing that provides the best

33:40

benefit. I think when you hear things

33:42

like this that like hey that will work

33:44

and that will work too and that this

33:46

will work too you know rather than the

33:48

dogmatic one way only approach um which

33:51

can become discouraging for people um

33:54

then I think it becomes a little bit

33:55

uplifting like well I've never tried

33:57

that I've actually never tried a total

33:59

body split I've never tried you know

34:00

that style of eating like it becomes

34:03

encouraging you might want to explore

34:05

and then you might finally get locked in

34:06

and say I really like this and then

34:07

you're off and running

34:09

>> on behalf of myself and all the

34:11

listeners, I really want to thank you.

34:13

And what I love about all of this now

34:16

that you've given us is that there's a

34:17

there's a backbone of logic, you know,

34:20

and and some consistent themes indeed

34:21

about consistency. And but the the the

34:24

logical backbone, I think, is what um

34:26

will enable people to really show up to

34:28

the table and stay there uh for training

34:31

consistently over time. I'm happy I was

34:32

able to make it work cuz I really I've

34:34

been watching your stuff for a while and

34:35

I really I love the science of it. I

34:37

like the way you think. I'm just really

34:39

fortunate that I was able to do it.

34:40

>> Well, I feel very gratified in hearing

34:42

that and and honored to have you here.

34:44

So, thank you so much.

34:45

>> Thank you.

Interactive Summary

This episode of Huberman Lab Essentials features a discussion with Jeff Cavalier, focusing on actionable science-based tools for fitness, mental health, and performance. They delve into training splits, emphasizing the importance of adherence and finding a program that fits an individual's lifestyle. The conversation also covers the integration of cardiovascular and resistance training, the nuances of stretching (active vs. passive, dynamic vs. static), and recovery strategies. A significant portion is dedicated to understanding muscle activation through the "Cavalier test" (inducing a muscle cramp to ensure proper engagement) and the concept of "muscularity." They also discuss injury prevention, highlighting the risks associated with the upright row and emphasizing shoulder mechanics, external rotation, and proper grip techniques to avoid elbow pain. Nutritional advice is provided through the "plate method," focusing on fibrous carbohydrates, protein, and starchy carbohydrates in balanced proportions, with an emphasis on sustainability and enjoyment. The importance of pre- and post-workout nutrition is also touched upon, with a focus on protein intake and listening to one's body.
