I was checking my max heart rate and saw it was 222 bpm with auto detect, normally it should be around 180.
I changed it to manually and put it on 180 bpm
But now i am in doubt when i want to put the heart rate manually do i put the 220 - my age or just the 220, as i have read that garmin calculates with 220-age?
Also 222 is a very strange number to get on auto as i have never seen my heart rate more then 175 bpm.
Thanks in advance
