This episode challenges the intensity-first mindset in fitness and reveals why complex movement—rather than harder movement—delivers the biggest cognitive rewards. Drawing on a major umbrella review, we explore how mind–body practices outperform traditional aerobic and resistance exercise for executive function, stress regulation, and long-term neural protection. By shifting the focus from blood flow to neurological complexity, we uncover how movement patterns that demand coordination, attention, memory, and emotional regulation stimulate the brain at a deeper level.
We break down the research on Tai Chi, highlighting its measurable gains in executive function and its ability to slow dementia progression. We examine dance as a multi-layered stimulus—movement, memory, rhythm, and social interaction—while showing why ballroom dance stands out thanks to improvisation and partner coordination. We also discuss how yoga strengthens interoception, stress control, and cognitive flexibility, offering consistent benefits across age groups.
You’ll learn how these practices combine into a five-pathway cognitive “cocktail”: motor learning, focused attention, relaxation, social connection, and complex movement patterns. The episode concludes with practical guidance on how to train complexity for better longevity and sharper thinking.

SPEAKER_00 (00:00):
Welcome back to the deep dive.
Today we are looking at somereally, I mean, truly
exceptional research you sharedwith us, all about cognitive
fitness.
SPEAKER_01 (00:09):
It's a fantastic stack of material.
SPEAKER_00 (00:10):
Yeah.
We're going to get into memory,longevity, and maybe uncover
some surprising habits that,well, that seem to be the most
effective for your brain.
SPEAKER_01 (00:19):
And what's so fascinating is how it really
pushes back against theconventional wisdom.
You know, for decades, theadvice has basically been the
same for your brain as for yourheart.
SPEAKER_00 (00:28):
Right.
Go hard, get your heart rate up,sweat.
SPEAKER_01 (00:30):
Exactly.
Push the intensity.
And what these sources suggestis that, well, while that's
definitely good for you, itmight not be the best path for
pure cognitive power.
SPEAKER_00 (00:39):
Aaron Powell Okay, let's unpack this then.
Because the common assumption, Ithink, for most of us is that
high-intensity training or, youknow, lifting heavyweights,
that's what gives you thebiggest neurological bang for
your buck.
But these reviews, they seem tobe pointing to a new champion.
And it looks a lot less like asprint and well, a lot more like
a slow-focused dance.
SPEAKER_01 (01:01):
It does.
And our mission today is tofigure out why, to really
dissect why these mind-bodyexercises, we're talking about
tai chi, yoga, certain kinds ofdance, why they seem to show the
largest effects when you putthem head to head with
traditional exercise.
SPEAKER_00 (01:14):
It feels like a fundamental shift in how we
should be thinking about this.
SPEAKER_01 (01:17):
It really is.
SPEAKER_00 (01:18):
So let's start at the highest level.
You sent over an umbrellaumbrella review, which, just to
be clear for everyone listening,that means they didn't just look
at one study, they looked atfindings from 20 other
meta-analyses.
SPEAKER_01 (01:32):
Yeah, this is the 30,000-foot view.
SPEAKER_00 (01:34):
So this is the big picture
practices against aerobic andresistance training.
What did that massive comparisonfind?
SPEAKER_01 (01:42):
Aaron Powell Well, the outcome was uh surprisingly
consistent.
The researchers looked at thepercentage of people in each
group who ended up with bettercognition than your average
sedentary person.
SPEAKER_00 (01:51):
And we assumed cardio would be at the top of
that list.
SPEAKER_01 (01:54):
You would, but that's not what the data showed
at all.
SPEAKER_00 (01:56):
Okay, so give us the numbers.
SPEAKER_01 (01:57):
All right.
So for the people doing aerobicexercise, about 57% showed
better cognition than thenon-exercisers.
SPEAKER_00 (02:04):
Aaron Powell 57.
SPEAKER_01 (02:06):
Okay.
The resistance exercise group,they did a little better.
They came in at around 60%, butthe mind body exercise group,
they just blew the others' way.
SPEAKER_00 (02:14):
And what was their number?
SPEAKER_01 (02:15):
It was approximately 68%.
So nearly 70% of thoseparticipants showed superior
cognitive outcomes.
unknown (02:22):
Wow.
SPEAKER_00 (02:23):
Okay, I have to push back a little on that because
that's that's kind ofconfounding.
We know for a fact that aerobicexercise is incredible for blood
flow, for producing BDNF.
Trevor Burrus, Jr.
SPEAKER_01 (02:34):
Brain-derived neurotrophic factor.
SPEAKER_00 (02:36):
Right, brain fertilizer, basically.
So if cardio is creating allthis growth, why on earth is it
coming in third place forcognitive gains?
SPEAKER_01 (02:44):
Aaron Powell And that is the absolute core
question, isn't it?
It tells us that while intensityand blood flow are, well,
they're necessary, they're justnot sufficient.
Trevor Burrus, Jr.
SPEAKER_00 (02:52):
So they're just one piece of the puzzle.
SPEAKER_01 (02:53):
They're one key.
But mind body practices are thewhole keychain.
That gap, that differencebetween 57% and 68%, it suggests
that things like complexity andfocus and the constant demand
for motor learning, that stuffmatters way more than just raw
cardiovascular output.
SPEAKER_00 (03:08):
Aaron Powell It's not just about pushing oxygen,
it's about pushing neurologicalcomplexity.
That 11% gap is huge when youthink about it in terms of
public health.
SPEAKER_01 (03:18):
It's a massive opportunity.
It suggests that for keepingyour brain sharp, you really
need to be doing things thatintegrate physical control,
spatial awareness, and attentionall at the same time.
SPEAKER_00 (03:29):
This is where it gets really interesting because
when we drill down into specificpractices, the effects get even
bigger.
Let's talk about Tai Chi.
SPEAKER_01 (03:37):
Yes.
SPEAKER_00 (03:37):
It shows these incredibly robust results,
especially for executivefunction, you know, the higher
level stuff like planning andworking memory.
SPEAKER_01 (03:43):
The evidence for Tai Chi is, frankly, exceptional.
There was one systematic reviewof 20 studies, over 2,500
people.
And when they looked just athealthy adults and executive
function, they found that about82% of the Tai Chi practitioners
performed better than averagenon-exercisers.
(04:06):
They are.
And this is the number thatreally stops you in your tracks.
59% of the Tai Chi group alsooutperformed people doing other
kinds of exercise.
SPEAKER_00 (04:14):
So even against the runners and the weightlifters we
just talked about, Tai Chi wasstill the more powerful tool for
that kind of thinking.
SPEAKER_01 (04:19):
For complex cognitive outcomes, yes.
SPEAKER_00 (04:22):
That's amazing for improving performance right now.
But the sources had this thispiece of clinical data that
makes this a must-talk abouttopic for long-term health.
The trial on dementiaprogression.
SPEAKER_01 (04:36):
Ah, yes.
This is, I would argue, the mostpowerful finding in the entire
stack of research.
They tracked people over time tosee who actually progressed to a
dementia diagnosis.
SPEAKER_00 (04:48):
And the results suggest a huge protective effect
from Tai Chi.
SPEAKER_01 (04:51):
A massive one.
One that traditional exercise inthis study just couldn't match.
SPEAKER_00 (04:56):
Okay, lay out the numbers for us because they are
pretty startling.
SPEAKER_01 (04:59):
In the Tai Chi group, over the course of the
study, only 4.3% of theparticipants progressed to
dementia.
SPEAKER_00 (05:04):
4.3, okay.
SPEAKER_01 (05:05):
Now compare that to the control group.
They were doing a standardWestern exercise program, you
know, for physical fitness.
In that group, 16.6% progressedto dementia.
SPEAKER_00 (05:14):
Aaron Powell Wait, hold on.
4.3 versus 16.6?
That's that's almost a fourfolddifference.
A four times greater protectiveeffect from Tai Chi.
That disparity is so huge, itfeels like it should change the
entire conversation aboutexercise for brain health.
SPEAKER_01 (05:30):
It should.
The implication is justunavoidable.
The unique mix of balance,complex sequences, and that
focus attention in Tai Chi.
It seems to build a kind ofneurological resilience that
pure cardio just doesn't.
SPEAKER_00 (05:43):
Aaron Powell It's not just moving, it's training
the brain to manage dozens ofthings at once.
Balance, posture, rememberingthe next move, breath.
SPEAKER_01 (05:51):
All in that slow, controlled way.
That sustained cognitive load isalmost certainly the key.
SPEAKER_00 (05:56):
Okay.
Let's shift gears a bit.
Let's talk about dance.
This is another one of thesepractices that shows incredible
synergy, physical, cognitive,and social.
SPEAKER_01 (06:04):
Right.
Dance is often seen as just fun,not as a serious neurological
tool, but it's a trifecta.
You get movement, you getmemorization and choreography,
and you get that crucial socialinteraction.
SPEAKER_00 (06:14):
And the data backs this up.
SPEAKER_01 (06:16):
Absolutely.
A big 2025 umbrella review foundthat about 73% of dancers showed
improved scores on the Mochatest compared to controls.
SPEAKER_00 (06:24):
And the Mocha is, of course, that standard cognitive
screening tool, the one theyused to look for signs of mild
cognitive impairment orAlzheimer's.
So improving those scores is avery big deal.
SPEAKER_01 (06:34):
A very big deal.
But it gets even more specific.
There was a networkmeta-analysis that compared
different styles of dance to seewhich one was, you know, most
effective.
SPEAKER_00 (06:44):
And what did they find?
Which style came out on top?
SPEAKER_01 (06:47):
Ballroom dancing.
SPEAKER_00 (06:48):
Ballroom.
That's fascinating.
Why ballroom over, say, salsa oreven just coordinated line
dancing?
They all require memory.
SPEAKER_01 (06:57):
They do, but the data showed ballroom produced
the biggest cognitive benefit,with about 81% of participants
outperforming controls.
81%.
And the thinking is that itcomes down to two things.
First, the improvisation.
When you're leading or followingin ballroom, you are constantly
making split-second decisions.
You're solving complex spatialpuzzles in real time.
SPEAKER_00 (07:17):
Right.
You're not just repeating apattern.
You have to react to yourpartner, to the music, navigate
a crowded floor.
SPEAKER_01 (07:23):
Exactly.
That dynamic awareness isincredibly taxing on the brain.
But the second element, andmaybe the most powerful, is the
social engagement.
SPEAKER_00 (07:32):
The connection with the partner.
SPEAKER_01 (07:33):
Yes.
That constant nonverbalcommunication and connection.
It activates these reallypowerful neurochemicals that are
known to boost learning andmemory.
SPEAKER_00 (07:43):
So it's that combined load, the physical, the
mental, and the social, thatpushes it past that 80% mark.
SPEAKER_01 (07:49):
Aaron Powell That's the theory.
And again, it just reinforcesthis theme that complexity and
engagement are the real driversof cognitive benefits.
SPEAKER_00 (07:55):
Aaron Powell Okay, so let's touch on yoga briefly.
Right.
Because it might not have thesame headline grabbing numbers
as tai she or ballroom, but italways shows up in this research
as a really solid, reliableperformer.
SPEAKER_01 (08:08):
Aaron Powell That is the perfect way to put it.
Reliable.
A meta-analysis of 12 studiesfound it produces these moderate
but very consistent effectsacross the board.
About 65% of yoga practitionersdid better than controls.
SPEAKER_00 (08:20):
Which is still a really strong result.
SPEAKER_01 (08:21):
It's a very strong result, especially considering
how accessible yoga is.
And while the percentage mightbe a little lower, yoga brings
something unique to the table.
SPEAKER_00 (08:30):
Which is what?
SPEAKER_01 (08:31):
Its real strength is in uh interoception, your
ability to sense the internalstate of your body, your heart
rate, your breathing.
SPEAKER_00 (08:38):
Ah, that mind-body connection.
SPEAKER_01 (08:40):
Exactly.
Holding a difficult pose whilemaintaining focused breathing
that trains your internalawareness, which is directly
tied to better emotionalregulation and attention
control.
SPEAKER_00 (08:50):
So it's that sustained focus coupled with the
deep breathing that acts as abreak on stress hormones.
SPEAKER_01 (08:56):
Yes.
It reduces the physiologicalstress that we know damages the
brain's memory centers overtime.
So even at 65%, yoga providesthis incredibly valuable
low-impact baseline forcognitive health.
SPEAKER_00 (09:08):
Okay.
So let's put all these piecestogether.
We have mind-body practicesoutperforming everything else
overall.
We have tai chi and ballroomdances, these absolute
powerhouses.
So why?
What is the secret ingredienthere?
SPEAKER_01 (09:19):
Aaron Powell The secret is synergy.
It really is.
The reason they work so well isthat they engage multiple
neuroprotective pathways all atthe same time.
SPEAKER_00 (09:26):
Okay.
SPEAKER_01 (09:27):
Think about pure cardio.
It's fantastic, but it'sprimarily hitting one major
pathway, boosting blood flow andgrowth factors like BDNF.
It's a single stimulus.
SPEAKER_00 (09:37):
Aaron Powell And these other practices are
hitting, what, five differentpathways at once, creating some
kind of exponential benefit.
SPEAKER_01 (09:43):
Aaron Powell Precisely.
They create this neurologicalcocktail.
Let's break down those fiveelements that are all wrapped up
in these practices.
SPEAKER_00 (09:51):
Right, let's start with the physical.
SPEAKER_01 (09:52):
Okay, first, you get moderate aerobic activity.
Your heart rate is up, you'regetting circulatory benefits.
Second, and this is crucial, youget intense motor learning.
You're constantly learningcomplex new movements, building
new roads in your brain.
SPEAKER_00 (10:07):
The complexity again is not just repetitive motions.
Okay, what about the mentalside?
SPEAKER_01 (10:11):
Third is the attentional training.
You have to maintain focus,whether it's on a Tai Chi form
or a dance step.
Fourth, they all have someelement of meditation or
relaxation, usually throughbreath work, which we know
lowers chronic stress.
SPEAKER_00 (10:24):
The neuroprotective break you mentioned.
SPEAKER_01 (10:26):
It is.
And then there's the fifthelement, which is especially
strong in something likeballroom dance.
SPEAKER_00 (10:31):
The social piece.
SPEAKER_01 (10:33):
Exactly.
Social engagement.
The cognitive load ofinteracting with another person
adds this whole other layer ofstimulus that you just don't get
exercising alone.
SPEAKER_00 (10:41):
So you combine those five
focus, relaxation, and socialconnection.
That's the cocktail.
SPEAKER_01 (10:48):
That's the cocktail.
And it's a stimulus that runningon a treadmill or lifting
weights, as great as they are,just doesn't replicate for the
brain.
SPEAKER_00 (10:55):
That synergy really does explain it.
That's why 68% is so much higherthan 57%.
It's less about how hard youpush your body and more about
how many different ways youchallenge your brain.
SPEAKER_01 (11:05):
It forces us to completely redefine what
effective exercise looks like ifyour goal isn't just muscle
growth, but but cognitivelongevity.
SPEAKER_00 (11:13):
Absolutely.
SPEAKER_01 (11:14):
Yeah.
SPEAKER_00 (11:14):
And that brings us to our final provocative thought
for you to take away from thisdeep dive.
Given that really starkdifference we saw in the Tai Chi
trial, where dementiaprogression was four times
lower, should we start thinkingof complex movement not as
exercise, but as a form oflong-term neurological
prevention?
SPEAKER_01 (11:32):
I think this research forces us to.
It implies that the prescriptionfor optimal brain health in the
future might focus a lot less onintensity and a lot more on
complexity and engagement.
If preventing decline is thegoal, the advice might be to
find a practice that constantlychallenges your motor learning
and your focus.
Learn a waltz, master a Tai Chiform, or just hold a complex
(11:54):
yoga pose with unwaveringattention.
SPEAKER_00 (11:57):
Because the brain thrives on complexity.
SPEAKER_01 (11:58):
The brain thrives on complexity.
And this data makes it prettyclear that the best exercise for
your brain is the one thatforces it to pay attention.
Welcome back to the deep dive.
Today we are looking at somereally, I mean, truly
exceptional research you sharedwith us, all about cognitive
fitness.
SPEAKER_01 (00:09):
It's a fantastic stack of material.

same for your brain as for yourheart.
SPEAKER_00 (00:28):
Right.
Go hard, get your heart rate up,sweat.
SPEAKER_01 (00:30):
Exactly.
Push the intensity.
And what these sources suggestis that, well, while that's
definitely good for you, itmight not be the best path for

What did that massive comparisonfind?
SPEAKER_01 (01:42):
Aaron Powell Well, the outcome was uh surprisingly
consistent.
The researchers looked at thepercentage of people in each

SPEAKER_00 (01:51):
And we assumed cardio would be at the top of

You would, but that's not what the data showed
at all.
SPEAKER_00 (01:56):
Okay, so give us the numbers.
SPEAKER_01 (01:57):
All right.
So for the people doing aerobicexercise, about 57% showed
better cognition than thenon-exercisers.
SPEAKER_00 (02:04):
Aaron Powell 57.
SPEAKER_01 (02:06):
Okay.
The resistance exercise group,they did a little better.
They came in at around 60%, butthe mind body exercise group,
they just blew the others' way.
SPEAKER_00 (02:14):
And what was their number?
SPEAKER_01 (02:15):
It was approximately 68%.
So nearly 70% of thoseparticipants showed superior
cognitive outcomes.
unknown (02:22):
Wow.
SPEAKER_00 (02:23):
Okay, I have to push back a little on that because
that's that's kind ofconfounding.
We know for a fact that aerobicexercise is incredible for blood
flow, for producing BDNF.
Trevor Burrus, Jr.
SPEAKER_01 (02:34):
Brain-derived neurotrophic factor.
SPEAKER_00 (02:36):

So if cardio is creating allthis growth, why on earth is it

SPEAKER_01 (02:44):
Aaron Powell And that is the absolute core

SPEAKER_00 (03:29):
This is where it gets really interesting because
when we drill down into specificpractices, the effects get even

Let's talk about Tai Chi.
SPEAKER_01 (03:37):
Yes.
SPEAKER_00 (03:37):
It shows these incredibly robust results,

The trial on dementiaprogression.
SPEAKER_01 (04:36):
Ah, yes.
This is, I would argue, the mostpowerful finding in the entire

They tracked people over time tosee who actually progressed to a
dementia diagnosis.
SPEAKER_00 (04:48):
And the results suggest a huge protective effect
from Tai Chi.
SPEAKER_01 (04:51):
A massive one.
One that traditional exercise inthis study just couldn't match.
SPEAKER_00 (04:56):
Okay, lay out the numbers for us because they are
pretty startling.
SPEAKER_01 (04:59):
In the Tai Chi group, over the course of the
study, only 4.3% of theparticipants progressed to
dementia.
SPEAKER_00 (05:04):
4.3, okay.
SPEAKER_01 (05:05):
Now compare that to the control group.
They were doing a standardWestern exercise program, you
know, for physical fitness.
In that group, 16.6% progressedto dementia.
SPEAKER_00 (05:14):
Aaron Powell Wait, hold on.
4.3 versus 16.6?
That's that's almost a fourfolddifference.
A four times greater protectiveeffect from Tai Chi.
That disparity is so huge, itfeels like it should change the

SPEAKER_01 (05:51):
All in that slow, controlled way.
That sustained cognitive load isalmost certainly the key.
SPEAKER_00 (05:56):
Okay.
Let's shift gears a bit.
Let's talk about dance.
This is another one of thesepractices that shows incredible

SPEAKER_00 (06:44):
And what did they find?
Which style came out on top?
SPEAKER_01 (06:47):
Ballroom dancing.
SPEAKER_00 (06:48):
Ballroom.
That's fascinating.

SPEAKER_01 (07:23):
Exactly.
That dynamic awareness isincredibly taxing on the brain.
But the second element, andmaybe the most powerful, is the
social engagement.
SPEAKER_00 (07:32):
The connection with the partner.
SPEAKER_01 (07:33):
Yes.
That constant nonverbalcommunication and connection.
It activates these reallypowerful neurochemicals that are
known to boost learning andmemory.
SPEAKER_00 (07:43):
So it's that combined load, the physical, the
mental, and the social, thatpushes it past that 80% mark.
SPEAKER_01 (07:49):
Aaron Powell That's the theory.
And again, it just reinforcesthis theme that complexity and
engagement are the real driversof cognitive benefits.
SPEAKER_00 (07:55):
Aaron Powell Okay, so let's touch on yoga briefly.
Right.
Because it might not have thesame headline grabbing numbers
as tai she or ballroom, but italways shows up in this research
as a really solid, reliableperformer.
SPEAKER_01 (08:08):
Aaron Powell That is the perfect way to put it.
Reliable.
A meta-analysis of 12 studiesfound it produces these moderate
but very consistent effectsacross the board.
About 65% of yoga practitionersdid better than controls.
SPEAKER_00 (08:20):
Which is still a really strong result.
SPEAKER_01 (08:21):
It's a very strong result, especially considering
how accessible yoga is.
And while the percentage mightbe a little lower, yoga brings
something unique to the table.
SPEAKER_00 (08:30):
Which is what?
SPEAKER_01 (08:31):
Its real strength is in uh interoception, your
ability to sense the internalstate of your body, your heart
rate, your breathing.
SPEAKER_00 (08:38):
Ah, that mind-body connection.
SPEAKER_01 (08:40):
Exactly.
Holding a difficult pose whilemaintaining focused breathing
that trains your internalawareness, which is directly
tied to better emotionalregulation and attention
control.
SPEAKER_00 (08:50):
So it's that sustained focus coupled with the
deep breathing that acts as abreak on stress hormones.
SPEAKER_01 (08:56):
Yes.
It reduces the physiologicalstress that we know damages the
brain's memory centers overtime.
So even at 65%, yoga providesthis incredibly valuable
low-impact baseline forcognitive health.
SPEAKER_00 (09:08):
Okay.
So let's put all these piecestogether.
We have mind-body practicesoutperforming everything else
overall.
We have tai chi and ballroomdances, these absolute
powerhouses.
So why?
What is the secret ingredienthere?
SPEAKER_01 (09:19):
Aaron Powell The secret is synergy.
It really is.
The reason they work so well isthat they engage multiple
neuroprotective pathways all atthe same time.
SPEAKER_00 (09:26):
Okay.
SPEAKER_01 (09:27):
Think about pure cardio.
It's fantastic, but it'sprimarily hitting one major
pathway, boosting blood flow andgrowth factors like BDNF.
It's a single stimulus.
SPEAKER_00 (09:37):
Aaron Powell And these other practices are
hitting, what, five differentpathways at once, creating some
kind of exponential benefit.
SPEAKER_01 (09:43):
Aaron Powell Precisely.
They create this neurologicalcocktail.
Let's break down those fiveelements that are all wrapped up
in these practices.
SPEAKER_00 (09:51):
Right, let's start with the physical.
SPEAKER_01 (09:52):
Okay, first, you get moderate aerobic activity.
Your heart rate is up, you'regetting circulatory benefits.
Second, and this is crucial, youget intense motor learning.
You're constantly learningcomplex new movements, building
new roads in your brain.
SPEAKER_00 (10:07):
The complexity again is not just repetitive motions.
Okay, what about the mentalside?
SPEAKER_01 (10:11):
Third is the attentional training.
You have to maintain focus,whether it's on a Tai Chi form
or a dance step.
Fourth, they all have someelement of meditation or
relaxation, usually throughbreath work, which we know
lowers chronic stress.
SPEAKER_00 (10:24):
The neuroprotective break you mentioned.
SPEAKER_01 (10:26):
It is.
And then there's the fifthelement, which is especially
strong in something likeballroom dance.
SPEAKER_00 (10:31):
The social piece.
SPEAKER_01 (10:33):
Exactly.
Social engagement.
The cognitive load ofinteracting with another person
adds this whole other layer ofstimulus that you just don't get
exercising alone.
SPEAKER_00 (10:41):
So you combine those five
focus, relaxation, and socialconnection.
That's the cocktail.
SPEAKER_01 (10:48):
That's the cocktail.
And it's a stimulus that runningon a treadmill or lifting
weights, as great as they are,just doesn't replicate for the
brain.
SPEAKER_00 (10:55):
That synergy really does explain it.
That's why 68% is so much higherthan 57%.
It's less about how hard youpush your body and more about
how many different ways youchallenge your brain.
SPEAKER_01 (11:05):
It forces us to completely redefine what
effective exercise looks like ifyour goal isn't just muscle
growth, but but cognitivelongevity.
SPEAKER_00 (11:13):
Absolutely.
SPEAKER_01 (11:14):
Yeah.
SPEAKER_00 (11:14):
And that brings us to our final provocative thought
for you to take away from thisdeep dive.
Given that really starkdifference we saw in the Tai Chi
trial, where dementiaprogression was four times
lower, should we start thinkingof complex movement not as
exercise, but as a form oflong-term neurological
prevention?
SPEAKER_01 (11:32):
I think this research forces us to.
It implies that the prescriptionfor optimal brain health in the
future might focus a lot less onintensity and a lot more on
complexity and engagement.
If preventing decline is thegoal, the advice might be to
find a practice that constantlychallenges your motor learning
and your focus.
Learn a waltz, master a Tai Chiform, or just hold a complex
(11:54):
yoga pose with unwaveringattention.
SPEAKER_00 (11:57):
Because the brain thrives on complexity.
SPEAKER_01 (11:58):
The brain thrives on complexity.
And this data makes it prettyclear that the best exercise for
your brain is the one thatforces it to pay attention.
