If I ever go back to a team that has daily morning stand-ups, I plan to ask that we use the meeting as an opportunity to do some morning calisthenics.

It would be good for all kinds of reasons. Helping people to wake up, discouraging long soliloquies, encouraging camaraderie, etc.

That being said, this paper uses 15 minutes of jogging as an example, and I suspect that might qualify as anaerobic exercise for many of us...
