The whole interesting part of the article to me is the (mostly unexamined) claim that sitting is still a problem in the exercising population. Everything afterwards is hypothetical discussion of mechanisms without looking at outcomes (at least for exercise vs no-exercise groups). > Since 2010, researchers have been keen to point out that sedentary behaviour is distinct from a lack of physical activity. You can get sufficient exercise per day, and still sit for too long. They could have delved into this a little more! The link is to a 2021 review (not 2010). Did they somehow RCT people into exercise vs no-exercise groups, or is this observational? Is it really just that our "active" guidelines are too low (30 minutes a day) and sort of assume a baseline active job during the other hours? (E.g., maybe guidelines should call for 2-3 hours of activity a day, some of which can be covered by non-sedentary jobs.) Anyway, just trying to figure out what to take away from this as an office worker who gets 1.5-2 hours of exercise a day.

That Sitting Too Much Is Bad Even If You Exercise has been discussed for maybe more than ten years now. There’s nothing particularly “interesting” about not substantiating it in a BBC article. And how would exercise compensate for sitting too much? That doesn’t make sense on the face of it. Exercise primarily builds strength and cardiovascular conditioning. It doesn’t (on the face of it) compensate for sitting at least eight hours a weekday if you’re an office worker[1] in addition to sedentary hobbies. Again from my naive perspective: sitting shortens the hip flexor which in turn can lead to anterior pelvic tilt which in turn can compress the lower back/spine both while sitting and while walking around (active). That’s just one example of a biomechanical conditioning that doesn’t just get fixed by exercise, or at least not without directed exercise (try to notice sometime how many people have an S-arched back as opposed to a more neutral (slight sway) lower back). [1] Shout out to managers who get the opportunity to “walk and talk”.
