I’m trying to determine if this is even possible and if there are any health implication to this. Some background: 36 yoa Weight 170lbs (77.1kg) Height 5’10” (178cm) My workouts consist of running 3-4 times a week, push-ups, pull-ups, sit-ups, and a fair amount of walking. I’ve only ever used an apple watch to record my HR during workouts I have always felt I’ve had an above average (on the top end) heart rate. My resting heart rate is somewhere in the 60s with the occasional (read at least daily) drop into the 50s. My previous highest recorded heart rate was 198 (during a 1 mile all out test). The circumstances behind this HR: It was on a track during a two mile run. I set a PR (at least it was the fastest I’ve run in the last 6-7 years, I’ve had faster in my younger days). I was paced the last 1/8 of a mile or so by someone who is considerably faster than me at this (and probably every other) distance. The times where I recorded this HR seems to coincide with the last 1/8th of a mile although I can’t be 100% certain. Interested in hearing from some of the more knowledgeable among you in regards to this. Thanks!
