And how do you know what a 20 out of 20 is if you've never really reached the point of volitional exhaustion?

So if somebody is just beginning to exercise, they might be at 70% of their maximal intensity, but they might think that they're at a 20.

So it takes time to learn kind of what your RPE is to be able to assess that accurately.

So I would say, you know, if people are more experienced with exercise, then you could use something like RPE to kind of gauge your intensity.

But those newer to exercise might actually have a lot of good feedback with the talk test.

I even kind of use that.

I mean, you know, it's,

If you're running with a group of people and you can have a conversation, okay, well, we're probably in zone two.

If I'm really struggling to like breathe, then I might be in zone three, four, even five.

So I think it's a great way to use the talk test.

Anybody can use it, but I think newer people might benefit more from that.

And I think also what people can think about doing is using a combination of all three.

You know, you can use heart rate, you can use RPE, you can use the talk test and maybe see if those, you know, correlate with one another during exercise, but use all of those to kind of inform your exercise intensity.

Yeah, the benefits of Zoom 2 training, I think, are kind of vast.

I mean, a lot of people will talk about how some of the main benefits are going to be, it really serves as a foundation for building your aerobic base.

You know, it's good for, maybe I should step back a little bit and kind of define what Zoom 2 is, maybe based on the exercise physiologist's definition of it, which would be

It's kind of the intensity where you're maximizing your mitochondrial fat oxidation.

It's a steady state exercise, less so than a threshold like intensity.

And so your lactate levels, it's measured during lactate is kind of the accurate way to do it.

So your lactate levels are steady.
