But this is the body adapting to a stimulus.

And everything we've talked about here, physical training, driving neuroplasticity, that requires adaptation.

And so some of that core stress response is involved in that.

the release of catecholamines we talked about in the brain, right?

Those are stress-related molecules that are driving adaptation so that your body can deal with the stressor better in the future.
