Is it still, what's more accurate?

Exactly.

I usually am not wearing, I do have a chest strap.

I have a Polish chest strap.

I have used it before, but I'm not typically wearing it when I'm doing a workout.

And so I think using my smart, my Apple Watch along with the talk test, because I often have someone with me when I'm working out, is like, okay, well, maybe it's not entirely accurate as I'm getting into my zone three, perhaps zone four, but I know I can't talk more than a word.

So it's clearly like it's good to combine them both.

So I want to there's there's a lot of interest in zone two training.

I talked about zone two training with Dr. Martin Kabbalah a little bit with Dr. Ben Levine.

And I want to ask you, maybe you can talk a little bit about what.

are the benefits of zone two training unique are there unique benefits of zone two training metabolically cardiorespiratory health-wise and as as you were explaining and defining some of these zones i was thinking to myself even what's the real difference between zone two and and what you would call zone three right this this threshold type of training as well right so um i'd love to hear

Well, you mentioned a pretty daunting number here.

You said 20 to 30 hours of exercise a week, which is far beyond what I myself do.

I'm more in the six to six and a half hours a week.

And so, you know, the question is,

If you are not doing 20 to 30 hours, let's say you're doing maybe five or even less than that, you're getting like two and a half.

This is where Dr. Gabala on the podcast was talking about high-intensity interval training being really time-efficient and having many of the same benefits as even like a Zone 2 type of training with respect to mitochondrial benefits, cardiorespiratory benefits, if not even better, if the same volume of exercise is performed.

In other words, if you're doing 30 minutes of Zone 2 and then a 30-minute high-intensity interval training workout, that you're going to have even...

more improvements in cardio-respiratory fitness than you would zone 2.

You would have better improvements in even mitochondrial density, for example, than you would.
