Well, for me, walking to my mailbox is a two mile round-trip down and up a mountain. Afetr a long day, I have to resist the urge to just drive down there...but I always feel better afterwards. You'll start to feel it too, Bob.

Do you live in town with an animal shelter close by? Call them up and offer to walk dogs for them. You get your exercise with some friendly company, and the dogs get a chance to get out, get more socialization, and get more exposure to possible adoptors than they would just sitting in their cages.
