If it's practical for you, consider getting a dog. Dogs need to be exercised every day so it forces you to get out and walk or run at least a couple miles every day. And by "dog" I mean a real dog, not some fragile inbred abomination that can't handle a run around the block.

And don't have a yard, or if you do, don't allow letting the dog into the yard be a stand in for taking the dog for a walk. Obviously that defeats the point for you, but it also doesn't do the dog any favours either.

My large inbred abomination (Bernese Mountain Dog, cute, cuddly, overbred) has never lived anywhere with a yard, so gets real walks.

My wife and daughter would love a dog, but we rent and already have a couple cats so it's not really in the cards right now (the cats alone aren't an issue, but trying to get the OK from the landlady for another animal isn't in the cards).
