fair point, but that's one nice thing about adding it to your commute: you are already out, so you can add walking time in short increments as you adjust your schedule. your commute is also variable in time. some days it goes faster, sometimes slower. pad it out so it is always the same length. it may not amount to much, but it is a start. same goes for every other errand you do.
lack of time is an issue of priority. i lack time to get all the work done that i want and need to. but i also know that i need those breaks. and that they potentially make my other work more effective.
higher intensity exercise takes more prep time. and probably a shower afterwards. so half an hour exercising at the gym might take 1 hour or more of real time. walking takes no prep time at all, so i compare that half hour gym with one hour walking.
I used to do it while coming back from work but lately I feel too exhausted and want to be home asap. Going to work no way, too much stress. But I go by bike which is still something.
The point of higher intensity exercise taking additional time requiring shower etc makes sense indeed. And I agree that walking is much more accessible: I can suddenly just decide to go out and walk, other types of exercise do require more of a plan or preparation.
Another thing I enjoy during walks is listening to podcasts. I cannot really stay focused on most podcasts unless I am walking.
