I do like Late. If I'm in the middle of a heavy training period, I take my RHR every morning. Here's my trick: I roll over on my side so that my ear lobe is jammed into the pillow. I can hear my pulse clearly and then I open an eye to my clock and count.

If it's elevated, I take a day off or do the minimum to get my blood moving like riding easily to work or walking the dog.
