Creating lesson...
1
That uncomfortable feeling that you feel when you are getting to that vigorous type of exercise, whether it's doing a run or it's,
2
you know, doing some resistance training where you're really doing hard things, that uncomfortableness, there's also a neurochemical reaction going on in your brain.
3
So we have an endogenous, that just means in our body, opioid system, okay?
4
Opioids, we're usually thinking of, you know, maybe exogenous ones that people take to help with pain relief, right?
5
Like morphine, for example.
6
We make our own opioids, endorphins, right?
7
Endorphins are something that we make.
8
Those are the feel-good opioids that we make in our brain.
9
You do make that with exercise, but you also make a type of opioid that makes you feel uncomfortable.
10
It's called dynorphin.
11
It's responsible for that uncomfortable feeling, that feeling that's like, oh, I want to stop.
12
I can't do this.
13
It's hard, right?
14
Dynorphin is is that uncomfortable like neurochemical that's being produced
15
and what that does is when your brain is making that
16
and you don't give up you keep pushing past it it
17
has this feedback loop in your brain where then your brain goes oh this is
18
that bad now it's i don't want to call it bad
19
it's the dysphoric feeling i better figure out a way to deal with
20
that and adapt and make something good so that later
21
when i have that uncomfortable dysphoric feeling i don't feel so uncomfortable
22
And so what happens is your brain starts to make more of these receptors.
23
Receptors are things that neurochemicals and neurotransmitters and things like that bind to to have an effect.
24
So they make more of the receptors that bind endorphins.
25
They're called mu opioid receptors and they become more sensitive to endorphins.
26
This happens only when you're getting that uncomfortable dynorphin you know flooding your brain
27
and so what happens is then later on
28
when anything happens that's a little bit pleasant you're going to feel it better
29
and for a longer period of time and so
30
that just makes everything easier when you have that sensitive
31
that sensitization to these endorphins
32
which we are making all throughout the day little things like
33
yo seeing your friends smile like all these little things they're making you make endorphins
34
And it's just a matter of how powerful are you going to feel that endorphin.
35
And so the uncomfortableness of the dynorphin is what is doing that.
36
But you have to engage in the hard, uncomfortable thing that makes you feel that dysphoric feeling.
37
That makes so much sense.
38
So if you force yourself to do some form of exercise, even just for a minute, even for three minutes, even for 10 minutes,
39
it paves the way for you to now really magnify all of the beautiful
40
and wonderful and comfortable things that follow it because you got the discomfort out of the way.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
