I walk daily at work, years ago my work published two different "hearth walks", quarter mile and full mile. The first is easy, walk through entry and do the full length of the deck. Having done this for years people comment when they don't see me. Its a quick little breather that serves two purposes, it lets me soak in nature - the deck is bordered by dense woods - and I get a reprieve from my desk.

throw in a good heartbeat app and I can push myself to 120+ beats for a good burst of morning and afternoon energy.
