And this was the Norwegian 4x4.
Okay.
And they, at the end of the two years, they tested everyone's hearts.
And from the beginning of the study to the end of the study, they saw drastic differences in how their heart functioned.
And it looked like their heart had anti-aged like 20 years from this exercise protocol.
And what the researchers kind of said, like that last little piece seemed to be, they think, was the thing that really pushed them to the next level.
Everyone's like Googling it right now.
Yes, Norwegian 4x4 is really difficult.
Okay, I don't recommend that you start with that.
Yes, it's four minutes of high intensity work at 85% of your max heart rate.
So that would be like running or doing some kind of heavy, high intensity workout.
cycling running whatever for four minutes and then giving yourself a break for three minutes and then going back to doing the four minutes and doing that four times so that's a really really intense high intensity workout how i would start is i kind of talk about how i started because i was like i can't four minutes like running as fast as you can for four minutes that's like a lot yeah
So what I did is I went for my first sprint, like I did a jog walk sprint and I would do 30 seconds of the sprint and then take a break.
And then I did that for eight minutes.
So you got four minutes of sprinting in there.
And that's how I started to work myself up to that protocol.
I still don't use that exact protocol.
Yeah.
Yes.
I do this thing called crazy eights.
