I finally got a pedometer, so now I can post the number of steps I take a day. I'm not sure of my stride length, so I probably won't have accurate mileage... and the pedometer seems to over-count the number of steps. BUT, it should give me some numbers to look at, and to try to eventually increase.

The pedometer counts not only the total number of steps, but also the number of "aerobic steps", which are those that satisfy:
(1) walk more than 60 steps per minute
(2) walk for more than 10 minutes continuously

So, I'll record the total steps, approx. mileage, number of aerobic steps, and number of aerobic minutes.
