That's excellent and so is the rest of your exercise. I think I mentioned in another thread that I'm getting a pedometer for my birthday. I read (I think it was in a pedometer review at Amazon.com) that an aim for perfect health is 10,000 steps a day. That sounds impossible to me right now, but if I can manage 45 minutes on the dreadmill at 3mph and walk more during the day (park farther away from my destination and use the rest room more!) I might be able to achieve it.

Why don't you stick your pedometer on in the morning and see how many steps you log in a day?
