There's a much more recent study that took again older adults and randomized them across three different groups.

One was like a low intensity group.

Another group basically did kind of zone two type work on a treadmill three times a week.

And the third group did a high intensity interval training intervention, which was the Norwegian four by four protocol.

So four minutes, 85 to 95% of maximum heart rate.

They had a three minute rest in their protocol.

They did that four times over.

Three times a week for six months.

That's pretty intense.

But what they showed was that that high intensity interval training group, they improved their fitness just as well as the zone two group, interestingly, but they had much better improvements in hippocampal function and maintenance of hippocampal structure on an MRI scan.

And they maintained that benefit for five years after the six month intervention.

So they worked really hard for six months, but that benefit was maintained for a really long period of time.

So amazing to be here.

Essentially, that's its core, most important function.

If it can't do that, literally none of the other functions matter, you could argue.

And it's something that we have to be able to do right until the end of our lives.

Yeah.

Lifetime, well, it's tested.

Lifetime no gear for me personally, but it's a drug tested version of the strongman sport.

So yeah, if you compete in natural strongman, then you get tested.
