10.000 is very hard to attain every day. I walk a lot and just get this value in very active days.
I recently visited Amsterdam with my wife. On the less active days, just leaving our room 3x a day for food and weed put us way over 10k steps every day. We were hitting 30k on our really touristy days. Now I'm back at my house in an American suburb and struggling to get 5k naturally.
From my point of view, the problem is most of the built environment caters toward cars and not enough toward outdoor living space.
It's a shame that we (Americans) don't build cities this way, instead requiring that we drive everywhere. It's bad for the environment as well as our health.
Take a fifteen walk once a day while sorting out your daily schedule, working on a hard problem, etc.
Personally, that cooped up feeling from being stuck inside all day is one of the reasons why I moved out of the city and onto some property. 30m of daily outside chores (work breaks, lunch breaks, replacement for a "commute") and I easily get 10k steps a day.
As someone who moved from a city to a rural area over the pandemic and saw their exercise suffer massively, this rings oddly to me. In a city I was getting huge step counts because there were so many places to go, so much to see and do! Leaving the house was immediately rewarding. Out in the boondocks, sure there's plenty of space to walk, but there's nowhere you can feasibly walk to.
I'm working on moving into a city. The plan is to get rid of the car and I think that'll make a huge improvement in health.
