Just for general fitness, it's oretty easy to do a mile a day (or more) on a treadmill. A fast walk is enough if running isn't your thing, two or three 10 minute sessions is all it takes. Not long enough to get coding before the next meeting? Hop on the treadmill and have a think. As a bit of added fun, it's easy to hack a treadmill to measure speed, stride, distance etc. I've got an old 42" TV in front of mine, great for watching videos, youtube and (using a PC) walking through CGI of various forms.
