I’m still going strong on the treadmill.  It’s been a week since I installed the treadmill and I’m pretty happy with the results.  On most days I seem to walk around 4 miles at a pace of 1 mph.  I haven’t really noticed any difference in my weight (not that I’m trying to lose any) so it’s not clear what the calorie burn is at this point.  But I do notice that I’m more focused on the tasks at hand once I’m on the treadmill.  Once I’m on it, I don’t want to stop what I’m doing, which is a good thing.  I’ve gotten much more done over the week since I’ve had it.
