No Intensity Minutes Logged

Any ideas why no intensity minutes are logged?

My guess is that you do not use HR Zones for the Intensity Minutes, and rather just the default method based on the 7 days Average Resting HR, and that this value is relatively high. 

I thought I had changed it to not use the default method since I do a lot of exercise. I cannot find where to check that setting now. 

Ok I found the settings on my watch it is based on HR Zones moderate is zone 3 and vigorous is zone 4. 

Which watch do you use? With older models, you have to stay more than 10 continuous minutes over the threshold, which in you case is 113 bpm. And seeing the HR graph, there does not seem to be any part longer than 10 over that threshold, which is practically identical to the dashed line of 114 bpm.

Mine is a 4s.

If you mean Vivoactive 4S, then it indeed requires 10 consecutive minutes above the threshold:

It had 20 intensity minutes and none were 10 consecutive minutes above the threshold line.

There is no threshold line on the graph. There is only the avg HR line, which was accidentally almost identical to the threshold of 113 bpm, in the case shown in your OP.. It does not mean at all that it is always that case.

Ok so at a minimum I need 10 consecutive minutes at 113 or higher heart rate (zone 3) for intensity minutes to log. Thanks.
