My personal experience doesn't agree with this. In college I had a habit of waking up with the exact minimum amount of time necessary to get to class. I would throw myself out of bed, get dressed and brush my teeth as quickly as possible, sprint down the stairs, and then race my bike as quickly as I could to class--only to fall back asleep as soon as I was in my chair.

In fairness, I was rather sleep deprived at that time.

I think you can commute-as-exercise, and commute-not-as-exercise. They're different engagements.

When I lived in Berlin, I would run in the mornings in the winter... it'd be below freezing. 1st 5 minutes I'd be cold, but once I started running-running, I was warm and the temps didn't bother me.

Then I'd come home, shower, breakfast and ride my bike to the office. I'd be cold.
