Sometimes a co-worker will spot me in the elevator and say, "Oh, getting your exercise before work?"
If I'm feeling snotty, I'll say something like "Nah, just getting to work. You don't consider driving to work exercise, do you?"
But actually, I do consider it exercise. I've got a route that can be a 5 mile or 10 mile TT or I can go directly home and spin easy for a 20 minute recovery workout. It's all good!
