So the individuals that got the treatment, the exercise treatment, I mean, this is a progressive program.

It's two years long.

You can't just take someone who's never really exercised and just immediately make them start doing five hours a week of exercise, right?

It's too much.

So it was a progressive loading.

These individuals over the course of six months sort of worked their way up to actually doing five hours of exercise a week.

A large amount of that exercise was cardiovascular exercise where they were jogging.

They were on a stationary cycle, getting their heart rate up to the point where they could have a conversation, but it was very, very breathy.

And then they also incorporated what's called high-intensity interval training.

Have you heard of this?

Of course.

This is where you're pushing yourself a little bit harder where you can't have that breathy conversation because you're working so hard.

You're getting your heart rate up to 80% max heart rate or more.

And then you recover for a period of time and then you do it again.

And there's a lot of different types of protocols out there.

They were doing one called the Norwegian 4x4 protocol.

This is where...

You are for four minutes going as hard as you can and maintaining that effort for four minutes.

You're not going all out.

It's a four-minute interval.
