Active minutes and exercise

[Maureen79]

When tracking and exercise with gps my sense is hardly tracking any zone minutes. For example after a two hour heavy walk it tracked only 7 active minutes in fat burning zone. Is there anything I can do about it? When not tracking an exercise and the Fitbit auto detects a walk the zone minutes are correct.

You have all the data available to check you Zone Minutes without relying on "feeling" that you should have gotten more.

Tap the Zone Minutes circle on phone app to see what heart rate is required for fat burn zone.  Then look at workout summary heart rate chart to see if you really were in the fat burn zone much more than the 7 minutes recorded.

Thanks for your answer, but that’s not what I mean. It is not that I have a feeling that I had more zone minutes. When not walking with gps my heart rate is higher/ more zone minutes than when walking with gps. That’s a bit strange… With my old tracker zone minutes were accurate. I’ve already seen allot of issues with the HR tracker on the sense. I guess this one also fits in.

Are you sure your "old tracker" was measuring 'Zone Minutes', and not 'Active Minutes'?  With the change to Zone Minutes, the heart rate ranges for the zones also changed, generally becoming harder to reach.

Yes, I’m sure it’s the same. The problem is really in exercise with or without tracking the exercise. A strange problem but it happens all the time.
