Nobody credible. The real question is how do you get people of their ass and start exercising? This includes me, I feel much better on days I make it to the gym.

Stop treating it as exercise and take up a physically active hobby. Hill walking, cycle touring, squash etc.

I think treating it as part of one's lifestyle, as you are probably alluding to, and not as an exercise routine/diet/etc, is the key.

What is the evolutionary explanation for this?

Does there have to be? Doesn't evolution produce a lot of things which are side-effects not goals?

yep. the biological term is "spandrel"

Compound studies find that 1hr of sports = 7hrs of additional life (up to 7hrs a week).

Do you have a link for that?

-No- YES! Found it: https://news.ycombinator.com/item?id=14117082 (sorry I was on mobile for my earlier comment)

If you read the study and point out a flaw, thank you for your contribution. If you make a zero effort "observation" which makes it clear you didn't even skim the abstract, you're adding nothing of value.

You're right. It's not arrogance though, just laziness?

So that's why Taleb deadlifts like a madman.

TIL (!). I deadlift (amongst other things), as I believe it's a fundamental movement (what Dan John calls "pick heavy stuff off the floor").

Here's a writeup Taleb did about strength training (whether I agree or disagree in totality is a separate issue, but we can all agree to 80% and disagree on the rest):

Sure, that too. Just cause I'm feeling extra pedantic, I'll point out that of those who are too lazy to click the link (the majority of people, including me most days), there is a small subset who presume their uninformed comment can dismantle the entire study--the arrogant.

Well done you. 50 lbs is huge. Since you are up so early and only have 40mins from waking up to gym, mind sharing your diet too (what you eat when)?

if you exercise 5+ days/week you dont have to worry about diet. its often the other way around that many people strugle with eating enough to gain weight/muscles.

Especially so if you combine weight training with something anaerobic like sprinting. I still follow a few basic dietary heuristics like not eating packaged foods, no sodas, and having the core of my diet be vegetables with lots of healthy oils, but past that I eat as much as possible and I am very, very lean at 82 kg.

> The real question is how do you get people of their ass and start exercising? You don't. You wait for them until they decide and act on their decision.

That is not an effective strategy. Decisions are backed by the environment (in a broad sense), so it's important to understand (for the sake of effectiveness) which changes can be done to the environment, to stimulate taking such decision[s].

I was being kind, sir.

What I was trying to say is: I don't give a flying raccoon if people want to exercise or not.

So yeah. No strategising from me.

Somewhat related, today I read "Researchers found that the foot's impact during walking sends pressure waves through the arteries that significantly modify and can increase the supply of blood to the brain." https://www.sciencedaily.com/releases/2017/04/170424141340.h...

Evolution doesn't care as long as you reach reproductive age and carry out that task properly.
