I found setting a really low Google Fit step goal and just trying to meet that daily goal 6/7 days a week was really helpful in just getting a basic foothold. And that basic foothold is kind of necessary when you're doing something you don't immediately want to do.

After that, I came up with fun ways to meet that goal, like specific paths I might take or things I might do. It feels much less like work if there's some sort of reward along the way, like a coffee or something.
