What is the definition of VO2 Max?

Everyone gives you the same definition, which is the rate at which your body can consume oxygen during exercise.

But why exactly does that matter?

That I think is often what's missing when people define what VO2 Max is, right?

You can look in a large language model, you can Google, VOT2 Max is the rate of which oxygen can be consumed during

exercise. Okay, great. Why do we as exercise physiologists care so much about V-O-2 Max? Why has it

become the most ubiquitous measure in all of exercise physiology? For very good reason, V-O-2

max is this integrated metric that reflects all of the bodily systems working together during

physical activity or during work to produce energy and to prevent fatigue. And that's why how much

oxygen we can consume matters. Dr. Gersicki, welcome back. Dr. Holmes, still to be here again.

So pumped to talk about VO2 Max and to just get into all the nitty-gritty details. We're going to start off by talking about the rigor behind the feature. I think that's really important to set the stage in terms of just the credibility of the data that folks are getting, I think is a really important place to start. And frankly,

we're really proud of it. And you had such a huge part in making sure that we had the level of rigor that we needed behind this feature. So huge shout out to your role in that. And then we'll go in just

the how, the why, how to think about training. You know, I really want to talk about, you know,

how to back in, I think,

for folks who are trying to design a training plan, it's thinking about, all right, how much time

do I actually have to train over the course of the week? And if I'm thinking about this 80-20 ratio,

80% of the time I'm in zone 2, 20% of the time. I'm in zone 5, kind of in that, like,

VO2 max threshold. What does that actually look in terms of how I plan my training? So we'd love

to kind of back into that just to help people think about their week in a more tactical way.

And I think we should probably like also talk about just we know strength training is a really

important component to kind of overall health and longevity. How do we think about strength training?

So if I have a total of X amount of hours over the course of the week,
