your response is proof once again, HN will go through any amount of mental gymnastics to avoid common sense on diet and exercise

I would love to know the waist size of the average HN user.

My money is on bimodal distribution.

Exercise just makes me feel good. To me, that's enough. Its not about a routine, or how I look, it's eustress.

I want a substance that tricks my mind into feeling this way about exercise. hold up gym bros! I don't want your technique. I want a drug like Ozympic that alters my behavior towards that lifestyle change.

You are describing forming a stable routine I don't think GP meant "routine" as in an elaborate set of exercises, but rather the daily/weekly routine of doing any exercise at all.

Maybe. I'm more describing making this important enough to you that you start looking for places to slot it into your day. Yes, a routine will likely form out of that but I think it's secondary to getting you to want to do the thing, which is harder (at least for me).

> I'm more describing making this important enough to you that you start looking for places to slot it into your day

I get where you’re coming from, and I think you’re missing the point. Executive dysfunction (for me at least) means I can “want to do the thing” a LOT, heck I can even have the motivation, but getting my brain and body to actually do the damn thing can feel insurmountable. There are certainly ways to work with and around executive dysfunction, it’s just difficult that one of the key aspects of it is that it makes the act of executing feel incredibly difficult.

The standard deviation referred to in the article is the effect size, and not the standard error of that estimate, which is what would be used to determine its significance.

No, that's just wrong. See the original source: https://journals.sagepub.com/doi/abs/10.1111/1467-9280.t01-1...

Thanks to scihub, we get the paragraph:

Earlier in the paper they define their effect size as:

g = (M_Post - M_Pre )/SD_P , where M_Pre is the preintervention mean task performance, M_Post is the postintervention mean, and SD_P is the pooled standard deviation.

I think the standard deviation mentioned is relative to overall population spread of cognitive performance, given that standard errors of the effect size are given separately?

Oh good, exactly what I'm looking for. If only the executive dysfunction didn't mess with my ability to form any kind of stable exercise routine.

An unstable execise rutine is better than no exercise routine.

I found that using a calendar or some kind of tool where I can add a mark every time I do something I want to form an habit of, it helped. Especially with the fact that I also add my mark even if it's only 5 minutes. So it reduces the pressure tremendously if I fail, or change my mind.

I moved from being mostly sedentary to being able to run 10km, swimming regularly, joining a field hockey team, doing archery. I also do hiit 3 times a week. Still my schedule is fucking chaotic, so beside the field hockey training which is on a fixed date, the other activities are done at, let's say, interesting and random time.

I don't say this to sound dismissive, which I think is all too common in discussions like this. If we're talking about aerobic exercise, you don't need to "form" anything. It's a monostructural movement. Buy a treadmill and jog on it for 20 minutes when you wake up. Buy a rower and do 5k every morning, or evening, or over lunch. Get a stationary bike and do 10 minutes on that whenever you remember to do it. This isn'…

This is a misunderstanding of what executive dysfunction means; somebody with executive function problems is not going to buy a treadmill much less use it every day.

The hardest part of bootstrapping a routine with executive function problems is getting on medication to fix the executive function problems

I'm pretty sure that HN skews far fatter than average, which is insane to think about since the average tech bro is far LESS fat than the average person. I imagine the average HN user to look like Richard Stallman.

Why do you think HN skews fatter than average?
