Heart rate way off
Hey, I just got my first ever garmin watch (first sport watch in general actually), it's forerunner 165 music.
I'm noticing that my heart rate on the watch barely changes tho. Even when I was sprinting on a treadmill and I checked the watch it said my HR is around 90 which I think was way off cause I was dying there lol. Anyone else experienced something similar?
I didn't start an activity on the watch, I just took a glance on the main screen.
