so I did 45 minutes of zone two and I say no you didn't really do it because you were going up and down and up and down and up and down and so that's not the same as spending 45 minutes in the dedicated uh Energy System you're right
The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

Um I but the the I guess I'm maybe speaking to a narrow subset of people who do exercise um who who who who understand its importance but um maybe aren't making progress because they've they kind of have hit a plateau on training stimulus and and they're you know they're they're and I see this all the time by the way. I talk to a lot of people and they think they're doing zone two but they're not. They're doing zone one and they're getting actually no training effect whatsoever.
