HIT Workouts Not Good For Me.

HIT (High Intensity Training) workouts such as fast runs, sprints, doing three sets of five burpees in two minutes lead to minor bleeding that shows up as pink sputum.  If I persist for several weeks the sputum becomes blood red, and looks pretty scary.  My doctor says I was smart to give up HIT workouts.

I first noticed this phenomena about December 2018.  I spent 2019 and spring 2020 experimenting with different running programs to see if I could "sneak" around this issue. August 2020, I finally accepted it, shifted my workouts to the range of what is called aerobic heart rate, for me about 110 - 120 beats per minute, and the bleeding issues ended.
