I’ve run 3 half-marathons before getting a fitbit and seeing my heart rate goes alarmingly high for my slow speed. Just figured out this weekend that I’m tightening my chest subconsciously and can see my heartrate go down when I relax it. How do I train myself to stop this subconsciously self-suffocating behavior?
