Pedometers

This is for anyone who uses a pedometer. I just wore one for the first time today because I was curious as to how far I walk during the day at my job. As of right now I am at 3.72 miles or 5900 steps for the day. I have never counted this before. I usually exercise and record either first thing in the morning or in the evening. Should I log this as additional exercise? It says so far I have burned 269 calories just during working hours. What do you think?
