Interval cardio on the cheap

Data graphed from my heart rate logger
M-F we're busy from about 5 to 7.  Often, there's not much time for the gym.  The heart rate profile depicted here is how I spent a portion of a recent lunch period.  I took the stairs over a period of about 20 minutes to get to the cafeteria.  Aside from a few odd looks on the stairwell, it was a pretty good cardio routine - and free.  Down stairs slow and back up even slower.  No matter how slowly I went, my heart rate got pretty high.
