Heart rate on Wrist Fenix 5X

Former Member over 7 years ago

HI

For the past 2-3weeks I am having trouble with my heart rate monitor (Not a Chest Strap) it worked perfectly previously and had no issues, but lately whilst training I get a reading of 75BPM when going full tilt. I use the Strength and Cardio apps from garmin while training. Please any help would be appreciated because this is so frustrating!!

Same problem here. For what I could observe, very fast hr increase is not handled properly.

Search the forum. Many, many posts about this across all the wrist based heart rate monitors

Having garmin vivoactive 3 (same sensor) with the same problem in cardio workout (training mode), this is clearly software bug, because earlier it was working nearly the same as chest strap. Now when I am doing pushups my heart rate lowers to 70-60bpm (watch strap is not tight). Contacted support, nothing, maybe they got few complains about this problem and do not take it seriously.

The general consensus and my own personal experience is that the wrist based HR monitors are fine for normal 24x7 monitoring and gentle exercise, but anything more strenuous it becomes inaccurate and you'd be better off using a chest strap. Some people indicate tightening the watch strap, others indicate not having it too tight helps, but to be honest, if you want accurate results for anything other than daily wear you really do need a chest strap.
