That's pretty hard.

So it's pretty much a sustainable, hard intensity for four minutes.

It's obviously not going to be maximal, but you're going as hard as you can for and as hard as you can sustain for that four minutes.

And then you follow that by a three-minute recovery period, which is very light, right?

You want your heart rate to come down.

You want to clear your lactate.

And then you go back into the four-minute interval.

So that's a four by four.

You're doing it four times.

That's a very good protocol to improve cardiorespiratory fitness.

There's a variety of other protocols out there Dr. Kabbalah mentioned.

So there's the

one minute on, one minute off, and you do that 10 times so that the 10 minute workout, well, it's actually 20 minutes, but 10 minutes of more high intensity training, where again, for that entire minute, you're going as hard as you can sustain for that minute, right?

It's not going to be all out, but it's as much as hard as you can go and sustain that for a minute.

And then you rest and recover for a minute, a very, very low intensity exercise.

And then there's things like even Tabatas.

So Tabata would be a 20-second on, 10-second off.

You do that eight times.

The 20 seconds, you're really going as hard as you can because, I mean, 20 seconds is, it's not long, although it seems long when you're going as hard as you can.

It actually seems quite long.
