Although I gave today’s workouts an overall RPE Level 4 rating, which is unremarkable, the observed lowest and highest heart rates seemed very remarkable.
One thing I have a habit of doing every morning is checking to see what my lowest/resting heart rate was during the night, and jotting it down in a notepad. The lowest heart rate during the night had been 53.
But after I changed into rowing clothes, put on the heart strap and sat on the rowing machine before starting to row, heart rate went as low as 51 BPM, which was 2 BPM lower than the lowest it had been during the night while I was laying motionless and in deep sleep!
Perhaps my body was anticipating morning coffee, with its dose of caffeine stimulant and was suppressing its own production of whatever comparable stimulant(s) it makes?
After today’s rowing session, I did a short session on the Concept 2 SkiErg. Heart rate managed to surprise me again by going to the other extreme and reaching as high as 185 during one of the SkiErg intervals.
After the workouts, I made coffee and enjoyed about 5 “cups” (30 liquid ounces) of dark black coffee during the next few hours of the morning.
Happy rowing to you!
