No "extra work" required. I walked my son to the bus stop this morning, and walked to meet him when he came home. Other than that, I did a bit of shopping (and took the dog for a short-ish walk, it's very cold and he's got almost no hair so long walks in the cold are not for him), and of course, moved around the house as normal. It totally blew me away to see that I was only 200 steps away from my 5000-step goal by dinnertime. I can see how adding another half hour or so of walking every day to what I did today could easily end up with a 10,000-step day on a regular basis. That's a nice thing to contemplate!
