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.
So you're going hard, but you're pacing yourself.
It's a HIIT workout.
And then you have a three-minute recovery where you're going very light.
You're really wanting your heart rate to come down.
And then you do that again four times.
So it's four by four.
And that...
workout they were doing twice a week and then went down to once a week.
Okay.

20 years.
So their hearts, these were 50-year-olds, 52 at the end of the trial.
