Walking is surely if one of the best things you can do to yourself if you have an otherwise sedentary lifestyle - actually uses a lot of muscles, feels less of a chore because you can easily be preoccupied by multiple other things in parallel (enjoying the view, thinking about things, having a phone call, listening to a podcast, thinking about your destination, etc.).

I've been working remotely for several years now, but one of my jobs used to start later late in the day, so I had some free time before that, which I used to walk around doing chores - felt great. Once I moved to the other job, with a more traditional schedule starting in the morning and ending in the evening, but still a bit off for my timezone, I stopped walking as much - gained a lot of extra weight just because I stopped "exercising" as much due to having awkward hours to do chores before or after work.
