It's a shame that you don't consider "normal" walking to be any exercise, because even walking to the bathroom and back is -so- much better than just sitting.

To provide an example, a 170 pound person would burn an average of 139 calories sitting down in an hour, vs. 324 calories per hour walking at a decent pace. That is a huge difference! Even standing vs. sitting is a significant difference (186 calories vs. 139 calories).

Now of course, calories aren't super important especially if you're not trying to lose weight. But walking works the major leg muscles, as well as helps to keep your heart healthy, improves mood, and so much more.

We should be trying to get at least 10k steps per day, and every step counts whether it's from during exercise time or during casual walking time.
