BTW, a lot of these people are pretty committed athletes. If you're not, and you're looking for something that's easy and obvious, try doing some pushups throughout the day. When I'm feeling antsy, sometimes I get up, do 20 pushups, and then go back to what I'm doing. Start small: two pushups count if you're not used to them.

I like to run, and if you're starting out, it's relatively easy to buy a pair of running shoes (try going to a running shop with a pair of shoes you already own; the staff should be able to look at your wear pattern and adjust the shoe they recommend accordingly) or a pair of Vibram Five-Fingers. Start easily: go out running for five minutes. Or ten minutes. Build up little by little.

Otherwise, I think the meta-advice of this article is that we make time for things that're important to us, which most of us probably already know, or know on some level.
