Welcome to Kevin's English Room Podcast.
Hello.
Hello.
Oh, a few, I don't know, I forget, a few weeks ago, you asked me the training, how to train and whether having heavy weight and slow training versus having very low weight and fast.
Okay.
Which one would be better? Those kind of questions, right?
Yeah, yeah, yeah.
And I asked that question to that guy.
Oh, okay, the guy, yeah.
Yeah, and he asked me, he answered, so the weight, first of all, weight doesn't matter.
Okay.
It's only the speed.
Oh.
That's what he said.
Okay.
So we thought it's like four types, like 重い、速い、重い、遅い、速い、速い、軽い、速い、軽い.
Yeah.
But weight is not important. It's just 速い運動 or slow 運動.
Okay.
You only have two types. And obviously, if you're carrying heavy things, you can't move very fast. So you have to adjust for each types of 運動.
And so, and then fast 運動, that builds your 速筋.
Okay.
And slow 運動, that builds your 縮筋.
Yes.
And so two different workouts.
Okay.
Yeah. And which one would be better? No. It's just two different works. And 縮筋 are bigger and outer.
So if you want to be just kind of…
Looking strong.
Yeah, macho guy, then you should do this 縮筋運動.
Okay.
And you want to like coordinate your body, your smoothness, and the connections and everything, you should do like slow things, slow 縮筋.
Okay, okay, okay.
And then both consume energy, it's like 糖 of your 糖.
糖?
Yeah, like グルコースって言ったかな? Energy in your body.
Okay.
And as 縮筋 are bigger than 縮筋, you have to, if you want to train both, you have to train 縮筋 first, and then next 縮筋.
Because if you do 縮筋 first, and then train yourself and consume your energy, and then try to do 縮筋, it's too big for your energy level.
So you can't properly train in that situation.
Okay.
Yeah.
So if you train both of those 縮筋 and 縮筋, 縮筋 first always, and then 縮筋 next.
Sorry, 縮筋 first and 縮筋 next.
03:02
That's the order.
I see.
If you want to do it in the same day.
Yeah.
Okay.
And that's what he said.
Is that two different, like, I know 縮筋 and 縮筋, is that like physically in a different position?
Like, are we looking at the same muscle, but just treating them differently?
Or is it a completely different part of your body?
It's not completely different.
I guess it's, but it's two different 筋肉.
Oh.
For example, he said, like, when we trained 肩, we don't have 縮筋 that much in 肩.
So if you do like fast 運動, that doesn't count.
It's not going to train anything.
Yeah.
Because you only have 縮筋 in this part.
Okay.
What, you know, works is just like slow 運動 to train this area.
I see.
Or maybe chest, you have both 筋筋 and 縮筋, so you can do both.
Maybe.
But every time I do chest, he said, like, fast and slow.
Fast and slow.
So maybe they have two things.
Yeah.
How slow is slow?
What I do is like one, it's like double or triple of fast.
Like one, two, three, four.
Oh, so when you push, you do fast.
And then when you pull, it's slow.
Yeah.
I see.
I don't know how.
And the slow is three times slower.
Yeah.
Three times.
Yeah.
One, two, three, four.
It's like that.
So it's three or four times slower than the fast style.
How fast do you do a fast?
Like as fast as I can.
As fast as you can.
Yeah, because I carry, you know, things.
Yeah.
So I want to do this like zero.
Yeah.
Yeah, yeah, yeah.
That's the rhythm.
But as I carry, like, you know, very heavy things, then I can't do it like this.
Yeah.
You can't, you won't fully go, right?
It gets slower and slower.
But try as fast as possible.
As fast as possible.
But that's okay.
Yeah.
That's okay.
To train my sokkins.
Oh, okay.
Yeah.
The undo itself is fast.
Like it's this kind of undo for the muscle.
Oh, got it.
So even if it's not physically moving, the impact on your muscle is still the same.
Right, right, right.
For example, if you're pushing the walls, of course the wall doesn't move, but it's still
sokkin undo.
Oh, I see.
Yeah.
I see.
I see.
Oh.
Yeah.
I see.
That's what he said.
Okay.
Yeah.
So for the walk or runnings, chikins are more important if you want jikyuryoku.
06:04
It's more, chikins are longer undo.
Sokkins are like...
Yeah, for sprinters, right?
Yeah, yeah, yeah.
But still you need at some point like fast undo on your walk or runs.
So, he said like, ma balansu desu ne.
Well, I mean, I'm sure that's okay.
Okay.
Yeah, yeah, yeah.
I'm working on my knees.
Oh, you're working on your knees?
Yeah, so that my knees don't hurt.
I'm working on it.
Training your knee muscles.
Yeah.
I'm doing that.
You're doing the slow things or fast things?
I'm doing like a medium.
Medium, yeah.
Yeah.
I'm not intentionally going for a fast or a slow one.
Just the normal...
Yeah, yeah, yeah.
Yeah.
Somewhere in the middle.
Yeah.
I think having muscles around knees can help your bones and consistence, right?
Hopefully.
Yeah.
Hopefully, yeah.
And then not lead to my knees hurting.
Yeah.
That's ultimately what I want to do.
Right, right, right, right, right.
You're not trying your knees have this, but...
Yeah, not to bend all the way.
Like the knee should consist, right?
Yeah, I'm also not...
I'm also making sure that I don't go all the way.
All the way.
Yeah.
Okay.
Is it difficult for you to not go all the way?
Yeah, kind of is.
Is it?
Kind of is.
Especially when you're like standing still.
Like you kind of want to like lock it all the way.
Like if I don't think about anything, I tend to just lock all the way.
So...
Okay.
It's lock to you.
You...
Like this.
Yeah.
I'm talking about my knees here.
Yeah, yeah, yeah.
Right.
Because like it's stable, right?
Because if you...
I want to like...
Right, right, right, right.
Like I want to lean against something.
Yeah, yeah, yeah.
It's easier, right?
So look straight doesn't mean...
Right.
I'm stopping in the middle.
Okay.
Yeah.
That's something I can't...
Can't imagine.
Yeah.
Yeah.
Right now, I'm like stopping because I think this is like straight.
When I want to go until here.
So that's more...
This is a lock.
Stable to you.
Yeah.
Okay.
Yeah.
That must be difficult.
Yeah, I mean, yeah.
It does take time to get used to.
Yeah, yeah.
Which I still haven't gotten, but...
Right.
Yeah.
Because you...
Okay.
Like my arms, for example.
My kata.
You have to stop right there.
Yeah.
You have to stop right there.
Yeah.
Right.
So if you don't think about anything...
Yeah.
You just...
It goes just like this.
Right.
Exactly.
I'll get there.
I'll get there.
Yeah, yeah, yeah.
It's a training, right?
Yeah.
All right.
Thanks for listening, guys.
09:00
Thank you.
Bye-bye.
