Intensity minutes no longer work with my original Instinct.

The only HR related settings I'd changed prior to noticing today that intensity minutes no longer register (I've zero for this week, after 4 x 10km+ brisk walks), was to raise the threshold for abnormal HR warnings, since stuff like just laughing a lot was setting it off.

After noticing the absence of any intensity minutes, I went in and set my resting HR to the average, since I noticed it was set to nothing. I also increased my activity class from 6 to 7, to more accurately reflect my current workout level. Though the later should actually make it harder to gain minutes, of course...

Suffice to say, after over a year of always hitting my goal of 150 intensity minutes by the second 10km+ walk, I'm perturbed I no longer earn them. How do I see when this stopped?

Also - now I look, I no longer even see a place to view intensity minutes within the Garmin Mobile app. Or the website. My perturbation is increasing... :-(

Okay, I found Intensity Minutes on the website. Last week I earnt 660, the week before last - 577. This week - zero. And this week I actually worked out more than the previous two weeks.

Please post a screenshot of the following Avg Resting HR, and another one of your daily HR graph.

OK, it is clear. You wear the watch only for the activity, hence it cannot measure your average Resting HR. The RHR of ~80 bpm is extremely high. And since the HR/HRM ratio is used for the calculation of the Intensity Minutes, you'd need to work really pretty hard to get any. Wear the watch also when you rest (better yet even when you sleep), and it will report the IM correctly (and not only during logged activities - it works also outside of activities).

I spent almost all of the 13 months I've owned my Instinct, only wearing it right before, during, and right after activities. It's never failed to register intensity minutes before...

Probably you were lucky that the HR/RHR ratio was higher than in this case. Compare the HR at individual activities, and the corresponding RHR at given days - that should give you the answer.

Specifically at the activity you posted, the HR is in the Z3 (aerobic - green) only for very short bursts. In order to earn intensity minutes credit, you must reach or exceed 10 consecutive continuous minutes where your heart rate is elevated above the threshold that is considered moderate intensity. At the activity you posted, I doubt it is the case (especially considering the RHR is very high too).

Compare it with other your activities, and I bet you'll spot the difference. If not, post some more screenshots.

Well, I'll try wearing my Instinct all day today, and see if it corrects whatever it has bungled suddenly with its understanding of my HR. Thanks for the advice.

You can also verify whether the HR Zones setting did not change in the meantime. Compare your older activities with the recent ones - the HR Zone settings is preserved in the history, so if it changed, you'll see it in the mouseover tooltip over the HR Zones bars on GC Web.

Seeing you barely touch the aerobic zone when walking at the pace of 9:45min/km, the problem may be in inadequately defined HR zones, using perhaps too high Max HR.

No, there doesn't appear to have been any such HR zone change. I'll see if I earn any intensity minutes when I exercise this afternoon with my usual 10km+ brisk walk, after wearing my Instinct since early this morning :-)
