We're not talking necessarily about just high intensity interval training, although that does include it.

We're also talking about maybe cycling or running or jogging to a point.

I think even jogging was considered more vigorous, right?

Like you had pointed out, you know, this study included adults that were up to age 79.

So they're definitely older adults, 65 and older, right?

So older adults did massively benefit from engaging in vigorous intensity physical activity.

I would say that, you know, most...

Most of people that are older and let's say they've never really done any kind of vigorous intensity activity, it's not that you have to just start it right away.

You can work your way up progressively, right?

I mean, that's just something to keep in mind.

Like it's easy to kind of just work your way up to it.

Start out with the interval walking and then like start in doing a little bit of light jogging in sometimes.

Or maybe you're just going to be that person that does these short, you know, one minute intervals.

chair squats or something that you're going to accumulate more of the shorter intervals throughout the day as well.

But it is important to point out that

As you're getting older, as you mentioned, the muscle mass, engaging the type 2 fibers because they're really going, your cardiorespiratory fitness is decreasing.

I mean, all of these things, there's so much, I would say, there's so many reasons why older adults should be trying to engage in some form of vigorous intensity activity and not just following the moderate intensity aspect of the guidelines.

Thank you, Brady.

There's definitely a group of people I like to push back when I, you know, anytime I like post or talk about doing the Norwegian 4x4 for some reason.

It's really, I'm not, I mean, I'm not talking about like nonstop Norwegian 4x4, like four times a day, every day, you know, five times a week.
