Coordination was not immediate. It took me 5 to 10 minutes until I was able to work without consciously thinking "step, step, step, step."
One of the biggest work impediments the first day was curious (and very understanding) co-workers. Most probably thought I was crazy, but few shared the sentiment.
My optimal speed seems to be around 1.4 mph.
My treadmill control does not have any distance memory. The distance clears shortly after the treadmill is stopped, so I don't have a good way to track total miles walked. I would estimate that I spent about 4 hours out of an 8-hour day on the treadmill in the first week, which calculates into roughly 5-6 miles per day.
I lost 13 pounds in the first nine days of January! I don't expect to maintain this pace.
