You're doing that entire thing every second that you're exercising and that your heart is beating.

If you were then to extend that throughout the entire minute, it would mean you've pumped over 1,500 ounces in a single minute through your heart.

I don't know if and how any of that information actually helps your life.

But me personally find it just endlessly fascinating to think about not only the performance side of this equation, right?

How fast can I run a marathon and things like that?

And that's really awesome and cool.

But what's the physiology behind it?

What does my body have to do to enable something like that to occur?

And thinking about the fact that, man, I'm going to have to pump

12 gallons of blood through my body per minute to be able to execute on something like that.

To me, that's maybe even a bigger joy than seeing somebody perform a race at a certain time.

Both equally impressive and fun, but love to see the physiology behind that.

To round this entire story out, let's move on to our third and final I, which is intervention.

In other words, what can you do about these things?

How much do they change?

And what do I have to do to see improvements in them?

If we work backwards through this VO2 max equation, as we've talked about, can we see improvements in our AVO2 difference?

Absolutely.

How so?

We're primarily looking for a couple of things.
