I just joined the board and I decided to take part in the exercise challenge. My question is: I walk to and from school every day, so do I count those minutes as exercise or do I just count the minutes which aren't included in my daily routine?

I think if you are walking at a decent pace that you can count it. What I do sometimes if I am doing something that is exercise but not very vigorous exercise is I'll prorate it. If I am walking from door to door with my son selling popcorn for four hours, I might count it as one hour of walking since we stop at each house. So I might suggest you count part of it if you are just strolling at a slow pace and all of it if you are walking at a decent pace.

Thanks. I walk pretty fast but my legs are long so I'm not really exerting myself so I think I'll just count it as half. Calculating exercise time is so much easier on a treadmill.
