No, it doesn't.

It's that high intensity that's a little bit uncomfortable where you're pushing at that max for about four minutes to build that VO2 max.

In the sports science world, it's always been the 4x4, the Norwegian 4x4.

Four minutes on, four minutes off, four minutes on, four minutes off.

But that's not three days a week.

No, not at all.

The Norwegian protocol is once a week.

And you feel so good when you're done.

So I can't run at the moment.

This morning I did explosive kettlebell swings.

I have a torn hamstring and meniscus, so I can't run at the moment.

It's a sacrifice of other things.

It's like we said about Pilates.

You know, if all you do is running, then that is definitely not the best way to be.

It's not the healthiest for your whole body.

It's not that you're unhealthy, but we're really talking about how are we optimizing your body and your hormonal health for a variety of different goals.

Yeah.

But also, if we look very micro at running, 58% of runners have a luteal phase defect.

That means that the second half of their menstrual cycle is not going to be able to last as long as we want it to, likely due to what Stacey was talking about earlier, this

relative energy deficiency coming back to the brain.
