With the caveats that this is just my very subjective experience, I’m not sure what you mean by “moderately active” or “an athlete”, and I’m probably taking your 80⁄20 more literally than you intended:
I agree there’s a lot of improvement from that first 20% of effort (or change in habits or time or whatever), but I think it’s much less than than 80% of the value. Like, say 0% effort is the 1-2 hours/week of walking I need do to get to work and buy groceries and stuff, 20% is 2-3 hours of walking + 1-2 hours at the gym or riding a bike, and 100% is 12 hours/week of structured training on a bicycle. I think 20% gets me maybe 40-50% of the benefit for doing stuff that requires thinking clearly that 100% gets me. Where the diminishing returns really kick in is around 6-8 hours/week of structured training (so 60%?), which seems to get me about 80-90% of the benefit.
That said: Anecdotally, I seem to need more intense exercise than a lot of people. Low-to-moderate intensity exercise, even in significant quantity, has a weirdly small effect on my mood and my (subjectively judged by me) cognitive ability.
You are both more correct than me, my wording was quite strong because I just felt like a discussion of the importance of a non-sendentary lifestyle for improvements in thinking was completely unadressed on the site. Hopefully someone else can read more carefully and help us to optimize based on our many varied characteristics. Thanks for the emotional dampening!
