Dr. Andy Galpin

I would love to talk to you more about that.

There's a lot of nuance and interesting things we can pull there.

but globally something we want to pay attention to.

So as we go into our next section here, where we cover those three I's, right?

How do I investigate?

my current cardiovascular fitness.

How do I interpret how good that is?

And then how do I intervene?

What do I do about it?

I want to make the point that just looking at your VO2 max is not enough.

Just looking at your resting heart rate wouldn't be enough.

You would also want to pay tremendous attention to your HRV and then various other factors like your respiratory rate.

Again, I'll do respiratory rate in a future episode.

I would love to talk to you for many hours about that.

I would actually tell you right now a little bit of a spoiler alert.

I think that is the most underappreciated of all these metrics.

I think it should be considered a vital sign and is potentially the most important thing that you can measure for overall fitness and health.

And quite honestly, it's the thing I pay the most attention to on a day-to-day basis of all of these metrics.

More on that later.

You're going to have to wait for now, though.
