I did something like this once; i had a 30 min walking commute to my office which was perfect (and was lucky enough this was a pleasant waterfront walk). Then I moved cities and went remote - no commute. After about a month I missed it enough that I set up a few 30-60ish minute "loops" and walked one or two of them every day (i.e. 2 short ones or 1 long one) and this worked pretty well.

If I found myself making excuses not to go, I'd mix in an errand that was about a 30 min walk away. Other people I know use a dog as an excuse for this sort of pattern too.
