You're about to hold a plank.
Just 60 seconds.
You know it’s coming.
That tension in your core.
The burn in your arms.
The mental countdown ticking away.
You’re already thinking,
Now imagine you push through that feeling.
You hold on.
Maybe your body starts shaking.
Your mind is screaming for you to stop.
You tell yourself just one more second,
and you make it to 60.
You’re feeling pretty proud of yourself.
(Cheers and applause)
But then you don’t stop at 60 seconds.
You don't stop at five minutes.
You keep going for an hour,
for two hours and then ten hours.
Yep, ten hours, ten minutes, and ten seconds.
That's exactly what George Hood did
when he set the world record for the longest plank in history,
a feat that most people would not believe possible.
I met George eight years ago when he set the record,
at that time, five hours.
And I’ll tell you this,
he just looked like the definition of mental toughness.
The focus in his eyes was razor sharp and he was drenched in sweat.
He was hurting.
You could see it in his face.
Feel it in his body, but he didn’t stop.
Later I asked him, George, how do you do it?
His answer surprised me.
The plank is 90% mental.
George told me he kept his mind busy
distracting himself by focusing on the conversations in the room,
drawing energy from the people around him.
But there was something deeper happening here.
We often think of grit as that mental toughness
that helps people achieve extraordinary things,
like ultramarathoners finishing races with broken bones.
But here's the twist.
Grit isn't just about willpower.
It’s rooted in biology, and the most powerful indicator to date is a protein
that we’re just starting to understand,
called Brain-derived neurotrophic factor, or BDNF.
Think of BDNF as fertilizer for your brain.
A protein that helps neurons, the cells in your brain,
grow, stay healthy, and communicate more effectively.
This protein is crucial for things like memory and mental resilience.
Many things increase BDNF,
including sunshine, blueberries, and antidepressants.
Exercise increases BDNF the most.
And the plank? Yes, that simple yoga pose,
just might be one of the best exercises
for building mental toughness.
I’m a clinical professor and diplomat
in the Department of Preventive Medicine at UCSD.
I’ve been doing clinical research for over 40 years.
In the clinic, many of the patients I care for
are so-called medically destitute.
Some had a heart attack or stroke in their 40s.
Some experienced a horrific accident in their 20s,
rendering them unemployable,
stripping them of everything and leaving them with chronic pain
or disability and a heavy dose of despair.
In no way am I suggesting something as basic as a plank can fix these conditions.
But more research is warranted to learn the potential benefits.
What makes the concept of grit and BDNF so compelling to me
are real life examples of individuals enduring these devastating conditions.
Researchers and clinicians still have a lot of questions about grit and the plank.
No one has ever studied BDNF during a plank.
Yet, what we know is this:
the most effective exercises for raising BDNF levels
are those requiring mental effort.
If you've ever done a plank, you know how quickly mental fortitude is required.
That, along with what we've learned from George,
leads us to believe the plank may be one of the most efficient
and effective ways of increasing BDNF.
You see, grit is not just for planks.
And BDNF is not just a theory,
it’s backed by science.
A 2005 article in the aptly named journal Hippocampus
described an animal study in which exhausting physical exercises
like continuous swimming produce less BDNF
than exercise that required mental focus, like navigating mazes.
In people, activities such as yoga, of all things
that combine physical effort and concentration,
have produced some of the highest levels of BDNF ever measured.
Currently, I’m designing a study for people like Daniel
to see if the plank relieves pain.
Daniel suffers from a very rare condition
known as Complex regional pain syndrome, or CRPS,
which is infamous as one of the most painful diseases.
There is no known cure.
As one patient said, the slight sensation of water dripping
on my foot feels like hot lead.
Despite living with this excruciating pain,
Daniel managed to do a plank for over nine hours
on his CRPS arm.
Think about that for a minute.
The most physically and mentally challenging exercises helped
one of the most painful conditions.
Now we have evidence that an important part of the answer lies in BDNF.
In August of 2024, an article appeared
in Experimental Neurobiology titled
“Modulation of BDNF by Physical Exercise.”
They found exercise doubled the level of BDNF.
I am here to raise awareness
so that this relationship between exercise, BDNF
and improving the quality of life may be studied further.
BDNF is hot in the research world.
I'm about to make it hotter.
(Cheers and applause)
George, Daniel and my patients deserve as much.
Now I'm going to leave you with the challenge.
The next time you feel you need more grit in your life, do a plank.
If you can't get on the floor, do it against a wall.
It only takes a minute, but that minute can be transformative.
Thank you. (Applause)
