The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
and yet when Studies have explored the consequence of doing multiple high-intensity interval training sessions and when I say high intensity I mean high intensity these are studies where lactate is elevated we'll talk more about lactate in a few minutes where typically people's heart rate is either close to or at their maximum heart rate for some period of time either 30 seconds 60 seconds 2 minutes or in
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

I think that high-intensity interval training, anything where you experience a burn, a lactate accumulation in the muscles, yes, it can stimulate more BDNF.
Why lactate from HIIT benefits the brain
And there's actually science showing that executive function is improved, and it totally correlates, and this is in humans, with lactate after high-intensity exercise. And it doesn't correlate with anything else, you know, glucose, like nothing. It's specific to the lactate.
and then there's also some brain benefits that are also really I don't want to say uniquely associated with high intenal anal training or vigorous exercise but also the benefits are associated with the lactate that you're producing which does come with increasing exercise intensity right
