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.
