This is so bleak. Go for a walk.

Why? My best friend uses a wheelchair and has dexterity issues in his hands due to a stroke. Exercise for him is (a) expensive and (b) really really really painful. If he could take a pill that simulated this it would be amazing for his life.

I was struck this past week to the extent that even a mild physical impairment can cause. I overdid it last week on a run and I spent this week nursing a swollen knee. What kind of exercise to do without involving my knee? I lift weights sometimes, but I can’t do that every day, and it also does not give me the mood altering effect that a good run does. I was drawing a blank glumly in an armchair when my wife suggested swimming at the local pool with pull buoys (so that I can keep my knee immobilized).

After a few experiments that felt more like drowning than swimming I finally got the hang of it. But it left me seriously worried about exercise in my future. After all, joint problems are likely going to happen again in my future. And I started to wonder: how do disabled folks do this? It must be incredibly difficult (and expensive!). I really am incredibly lucky across multiple fronts to have the life that I have.

> Our bodies are mechanically optimized for running at every level My flat feet (and those of my mom, and those of one of her parents, ad infinitum) would beg to differ lol Also, most of the energy our bodies burn to run just turns into heat, it's all very inefficient... even if sweating itself works pretty well, and even if our heat tolerance is high assuming we have a source of fresh water

I mean, would you prefer we add in some evolutionary pressure?

Note also that there are numerous champion runners with flat feet.

Until you injure something particularly nasty, like a joint, tendon, muscle tear, etc...

I injured my knees by running more than my knees could handle. Instead of never exercising again, after a 2 month long break I started incorporating other forms of exercise in my run schedule. Now I run longer and have other parts of my body feel better. There’s a hundred reasons to not exercise but you only need to focus on the one reason why you need to keep doing it.

Use it or lose it!

My friend has fixed his flat feet by focusing on yoga poses that engage the “knife edge” of his feet (ie: the outside). It took some time but he reckons it’s very noticeable. Maybe worth a try?

Maybe not a drug. But if the improvements in health come from bio chemical signals, it should be possible to activate those signals without engaging in exercise. Eventually?

It would take a lot of different drugs to simulate what exercise does.

- Impact and stress strengthening the muscles, bones and tendons / ligaments

- energy use that leads to better sleep

- increased blood flow, development of new capillaries, stretching of blood vessels

- if you exercise outside, exposure to sunlight

- the release of all the associated neurochemicals

I have a suspicion that anything designed to mimic exercise would hurt as much as the actual thing given that so many of the benefits of exercise involve damaging bone and tissue then repairing it

I’ve read in a few places that the flat feet comes from wearing shoes that don’t allow your toes to splay, which causes the muscles that create the arch to atrophy. Not a scientist and have never had flat feet, so can’t confirm, but I recently started wearing zero drop shoes and definitely feel a healthy soreness as my feet get stronger.

How much of that is due to only using two limbs? Which also makes us slower I guess.

Exercise "simulate the arduous tasks that were once necessary to make it through a life" makes sense, as most of our ancestors were blue-collar workers and farmers. I try to integrate more physical activity in my life, which seemed like labor before, but now feels like life-saving activity. For example, I am intentionally trying to fix/diy things with my house like painting my garage, mowing my lawn instead of hiring someone else to do it, and even learning woodworking and gardening. Even in the heat of the summer, I feel more invigorated working outdoor whenever I can, and helps offset the sluggishness I feel after a day of sitting, coding, and staring at the monitors at work.

Ask anyone in the army how all those years of running drills have affected them as they got older. It’s not so rosy. Lots of knee problems in that group. Above average practice of running throughout life also increases likelihood of requiring pacemakers later in life.
