Ok... What can I possibly doing wrong.
I ride my indoor bike using a Wahoo tickr wrist HR monitor and save my data in Strava.
When exporting to Garmen connect & compare the Vivoactive HR vs Wahoo tickr I have a significant difference.
Wahoo High HR 150 bpm compared to the daily HR on my Garmen connect is only 102 bpm.
Same profile setup for both.
