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.

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.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
is it beneficial at any age young or old i would say emphatically the answer to that question is yes
as we get older even certainly at my age you know it's unless interested in now how well i'm performing for any reason other than my overall health and therefore i put more of my relative exercise time into zone two
it's my belief that this is the most important place to be training your mitochondria and if we understand that mitochondrial function and the deterioration of mitochondrial function is one of the hallmarks of aging then anything we can do to delay that process and enhance mitochondrial function it's going to be a benefit
is it beneficial at any age young or old i would say emphatically the answer to that question is yes and of course a younger person is going to have more bandwidth physiologic bandwidth i mean to explore a broader array of energy zones so um you know a younger person is going to be able to make zone 2 probably a smaller part of their overall exercise program and whereas i think as we get older even certainly at my age you know it's unless interested in now how well i'm performing for any reason other than my overall health and therefore i put more of my relative exercise time into zone two
one of the things about zone two that i really enjoy is it's just not that hard
So um we've obviously talked about the central part of metabolism which is respiration and ATP generation and the leakage that occurs there and and basically unfortunately that just appears to be inevitable. U yes that's totally right. We will never stop the oxygen in our environment. So yeah, um I do like to tell my patients that this is why I kind of harp on them to do a lot of zone 2 cardio training, right? So zone 2 very specifically by definition, right, is the canonical exercise you would do to maximize fat oxidation, which of course implies the most efficient use of the mitochondria. And the hypothesis, because I don't think, you know, we don't have proof of this, but the hypothesis is training at that level for specific periods of time throughout the week, is is a way to improve the health and function of your mitochondria, which would hopefully imply that you're reducing that degradation of function.
