You joke but perhaps we need to (scientifically) find the minimum number of steps for a reasonable lifespan in tabular form for a given weight, lifestyle, diet, occupation and ethnicity. The law of diminishing returns will apply after a certain amount of physical activity. So will negative consequences of too much exercise where you damage your limbs.

Worrying about over exercise is like worrying about starting another ice age fighting global warming.

Untangling cause and effect (it clearly works both directions) is near-impossible, the intensity of the steps obviously also matters, and anyone trying to exercise to the statistical minimum before diminishing returns kick in probably has other issues. I don't think many people need to worry about limb damage from over-walking, and the ones who have already experienced limb damage need to find alternative exercise rather than minmaxing steps...

The absolute worse thing you can do for your knees and other joints is be obese. The constant weight and stress wrecks you. This is also why young, fit males come out of the military with wrecked knees, not because of all the running, but because they march around constantly carrying 100+ lb packs, on bodies that would be at a healthy weight of 150lbs. There's even evidence that distance running strengthens your knees, contrary to common knowledge. https://archive.ph/utsUF https://archive.ph/utsUF Worrying about too much exercise for the average person is like worrying about drinking too much water on a desert hike.

Isn't that overthinking it big time? Biologically humans have evolved to walk roughly 10-15km a day. You really have to overdo it to get to negative consequences of light physical activities such as walking. Just talking a one hour walk every day surely doesn't get you anywhere near the red zone, provided you're otherwise reasonably healthy.

There’s not much science for the ultramarathon folks, but in general more is better. This talk of negative consequences of too much exercise has no grounding in reality.

  The people I see that cite the risks of "over exercising" are exclusively people in bad shape. My sister in law, sedentary and textbook obese, insists that running is dangerous for anyone due to the "extra stress it puts on knees." It's just an excuse people use to convince themselves that they're doing the right thing by not moving much. I see it too with people not eating healthy foods like vegetables because they read somewhere that the pesticide residue or whatever is worse for you than just eating processed food all day.

    I’d guess that starting to run while obese would indeed do substantial damage to the joints.

  I think it’s important to note that you are assuming a gradual increase in activity over time as well as adequate food and rest between sessions. In the limit case things like rhabdomyolysis definitely exist and in the less-extreme case, you can have problems with connective tissue injuries from increasing the load or volume of exercise too fast. Over the long term, you can also have health problems and injuries caused by doing too much exercise relative to how much food and rest you are getting. All of these are real possibilities if someone started an intense exercise program after 20 years of completely sedentary life as an adult. That said, we are discussing this in the context of walking a bit more, which should be very well-tolerated for pretty much everyone as long as they don’t have other significant health problems and work up gradually. For example, if you take 1000 steps a day, space out the increase by each week increasing your daily steps by 500-1000 steps a day until you reach 10000 steps a day over the course of a few months (temporarily pause or reverse the increases if you see anything other than passing muscular discomfort). This also explains how ultramarathon (or other “extreme” physical activities) can be tolerated without much issue—bodies are very good at adapting to the loads that are placed on them as long as that increase is gradual and they have enough food and rest to rebuild after particularly intense bouts of activity. A further corollary is that over the long term, being sedentary is not well-tolerated at all, so maintaining a certain baseline level of physical activity is definitely a better idea and as long as your body isn’t giving you any feedback to the contrary, you shouldn’t avoid high loads or intense activity just out of abstract fear of injury.
