"Never exercise for over 45 minutes"

Curious. Is that because long distance runners primarily run with their legs and sprinters run with their whole body?

Seems like the long distance guys hardly move their upper body, whereas sprinters look like their whole skeleton is about to jump out of their bodies from head to toe.

I has mostly to do with the form of exercise itself (and the many variables within that), their nutrition, and other factors, some of which they can control, some of which they can't.

"Regular exercise is good" is one sentence and not flawed! I agree, just breaking chops.

Lol, my first reply was "any one sentence thing is wrong" then I noticed it was one sentence long...

I would be more worried about the prolonged effects of elevated cortisol levels due to stress. Increased basal levels of cortisol would mean you are constantly exposed to its catabolic effects. Unless you are swimming the English channel, stress is more likely to burn your muscle than a workout.

That is what the studies I outlined in the OP said: elevated Cortisol levels for long periods causing excess catabolism.
