You might be in for a pleasant surprise. I got fitbit (electronic pedometer that syncs with the computer) and this lovely little thing is honest and does not care whether I intentionally went for a walk or just went up and down the stairs many times getting hampers into the laundry room, getting groceries out of the car, cleaning after the cats, taking flattened cardboard to the special cardboard recycling receptacle on the other end of the apartment complex, and, just pacing the floor because when I talk on the phone, I walk and not sit. And in the evening, sometimes, just those steps taken while doing chores and pacing the floor add up to the daily recommended step count, without ANY intentional exercise.

It is an expensive thing ($99) and it needs maintenance - I charge it every night - and the plastic wristband into which the "bit" goes is ugly, but I very much enjoy having it because it has enabled me to break away from the (ridiculous if you think of it in the context of world history...) notion that exercise requires special effort, special clothes, special structure, special set of mind.

For the "honest count" that fitbit provides me I would wear the ugly wristband...
