That's kind of these days what my primary goal has been.

And so, you know, I might train differently from somebody who just wants to get healthier or improve their health span if they're in middle age or older age or

you know, even younger people who are just kind of getting into exercise.

So, um, yeah, it's important to define the goals and that will kind of determine how you want to train.

And even though my goal is to optimize, to run a fast marathon, you know, given that it's not my full-time job just to run fast and I have other goals like reducing my injury risk and just having a high level of vitality.

I also want to, you know, train for brain health like you, Rhonda.

I think I find the benefits of exercise on my brain.

One of the kind of most salient benefits of, of exercise.

Um,

But I also just want to be strong, be able to do things and maintain health late into life so I can keep doing the things that I want to do.

So I think the way I approach training is try to optimize for performance, but not at the extent of sacrificing some of my other health metrics.

So I try to blend a little bit of the two.

75 to 80 is, you know, I've tested a few times throughout my life.

And so it's somewhere in that range.

But I mean... Maybe an elite level VO2 max, but my running times wouldn't be considered elite by most standards.

I think people will be pretty familiar with the term cardiorespiratory fitness.

It's sometimes used interchangeably with VO2 max or your maximal oxygen consumption.

It's kind of a very popular biomarker these days with, you know, like you said, and we'll talk about later, correlating with longevity and so on.

So cardiorespiratory fitness is sort of the exercise physiologist's measure of

Aerobic fitness, it's very popular as an endurance performance marker, or that's traditionally how it was thought of.
