> 10 hours a week of exercise

Honestly, only a hypochondriac or a narcissist would consider 10h/w acceptable. Everyone is too busy trying to stay alive.

The number only makes sense if you're a body-builder or an influencer who trades on appearance.

Evolution didn't spend millions of years so we could sit 8 hours a day and slouch through the rest.

10h/week of moderate exercise should be straight forward. moderate exercise includes stuff like cleaning and other chores, playing with your kids, walking to the corner store, et cetera.

I don't think those count as "moderate to vigorous" exercise, at least for most of the time you're doing any of them.

Consider the speed/vigor with which one does something, whatever it might be. It can be quite the range.

The study specifically includes walking in their list of exercises. You probably do want a mix of exercises -- 90 minutes of vigorous exercise a week is a standard recommendation, but 10h a week of vigorous exercise is probably contraindicated for the average 57 year old in the study.

Walking is good exercise for anybody who is out of shape.

Walking as moderate exercise is not "just walking" though. You need sustained speed

I don't think 10 hours per week is unreasonable or impossible. And I don't see why you need to be a hypochondriac or narcissist to prioritize physical activities. The article does not define the required level of exertion, but I assume things like biking, ping-pong/pickleball, soccer, etc all count. A lot of physical activity can be cheap, though it is more challenging in the winter.
