Yeah, so I think if you take a group of people who have never trained before, kind of unfit people, and just give them a lot of lower intensity or, you know, what people might refer to as zone two training, everybody is going to kind of improve because you have, it's a new training stimulus.

You know, you've never trained before.

You add some exercise.

Okay, well, obviously you're going to get fitter.

And you mentioned the concept of non-responders, which has kind of been around in like exercise physiology for a while.

And it essentially refers to, you give people exercise training program.

There are some people who,

don't improve for some reason or another.

They're VO2 max.

And I think there's kind of a debate on there where it might just be due to like a measurement error instead of actually a non-response.

But like you just mentioned, when you give those people high intensity interval training, everybody responds.

There's some kind of recent studies that show that very well.

You just increase their dose of exercise or their intensity or both, and they improve their fitness.

So they're just basically not doing enough.

And so that points to the fact that

If you want to get better, you need to add in some higher intensity interval training.

Obviously, you can increase the dose of your moderate intensity training to your volume, but adding a greater stimulus, you know, that seems to be the main benefit of doing high intensity training.

You can't just do the same thing.

You can't just do low intensity training all the time.

You need to not only mix it up for variety, but you need to give your body a greater stimulus if you want it to adapt and improve.
