What’s worked for me personally is just walking to/from my car at work, it just fits so naturally into my schedule that I don’t have to put any thought into it or have any struggles with willpower, I just do it. I park as far as possible away from the building, so there’s no conflict with just walking in the door, then take a few laps around the building. I work on the 4th floor, so I take the stairs and also do a few laps up and down the stairs before getting to my desk. I do that twice a day (when I get in, again for lunch), then at the end of the day I take one more lap before I get back to my car. I get in +10k steps on a daily basis when I’m in the office consistently and without even really thinking about it or putting in “extra effort”.

My problem is actually keeping it up when I’m not at the office, because then my routine sort of falls apart. I’ve tried building up routines for when I’m at home or on the weekends, but one thing or another seems to come up consistently and I haven’t been able to get them to stick.
