And I think what people need to realize is when we talk about the risk of injury and sleep, it's like the bowl comparison I made, right?

Like if you've been sleeping great overall and you have one bad night of sleep, I very much doubt it raises your risk of injury.

It's more about what you're doing.

Just like if you've been sleeping like crap, sleeping great one night is not going to – oh, you're all recovered and everything is back to baseline.

Like no, that's not how that works.

We know like sleep deficits are tough to make up, right?

So I think it's fine to go train after a night of poor sleep.

Just auto-regulate, right?

If you feel worse – and I tell this – I actually –

I've had clients, I've had to have them stop wearing wearables like Oura rings or watches or whatnot because they end up noceboing themselves because, oh, my battery is low or like my body battery is low or my HRV is messed up.

And it's like, okay, well, maybe that will have an impact.

But you could just go test the thing.

Like you could just go do it.

And so –

And the same thing people talk about like for females, we kind of discussed this a little bit, like training for your cycle.

There's really not a lot of evidence that you need to train differently for any phase of your cycle.

But if you personally feel worse during a certain phase of your cycle or even a certain day, who cares if it's the cycle, if it's the sleep, if it's the – who cares what it is?

Reduce your load.

So again, where X's and O's meets practicality.

If you look at the mechanistic stuff of like BMR, total energy expenditure, you know, all the like hard metrics, they don't really change with menopause.
