Vivoactive 5s and indoor rower: HR reporting very poor

4494210 24 days ago

I have and indoor rower Concept 2, that connects to my Vivoactive 5s heart rate montior. Either via the machine (PM5 monitor) or via the app (ErgData). So far so good. However, the HR that the watch produces has nothing to do with reality: far too low, takes ages to catch up. I read that the strap has the same problem. How to fix this?

Activities that flex the wrist may create an effect similar to wearing the watch too tightly and restrict blood flow. When this occurs, the watch may have a difficult time detecting an accurate heart rate. You can adjust the watch slightly farther up the wrist, or wear a Garmin heart rate monitor strap for these activity types. Refer to your owner's manual to determine if your watch is compatible with an HRM strap.
