Enable HRV recording on Garmin watches
Fenix 5, Fenix 6, FR 945 and newer devices
Enable the HRV recording at
Settings -> Physiological Metrics -> Log HRV
Garmin 910XT, FR 620
Turn on your device and enter the Menu. Now press UP and DOWN for 10 times. You will enter the so-called diagnostic menu. Select and change HRV to enable HRV data recording.
We assume no responsibility for possible problems! You do this on your own risk. (Anyway, we enabled HRV on our devices as well and did not experience any issues so far.)

Have a look at the5krunner.com. You’ll have to download a *.fit file and save it on your device.
