I understand that heart rate - in itself - is not a measure of fitness. However, I'm interested to know if there are any dangers or concerns with a heart rate that is too low. I am FAR from being near the excellent fitness of the regular passionate cyclist (42 years old, 5' 7" and 178lbs). My resting heart rate has declined from the low 50's a year or so back to under 40 now (around 38 or 39).
Anything I should worry about?
