My watch series 6 just started not counting my whole walk for my exercise ring. Why is that. It use to up until yesterday and today.

The exercise ring (green ring) will only count exercise when your heart rate has increased - not sure how far it needs to go, though.

Just as an example, if I walk at a 20 minute per mile pace it doesn’t count for me. If I walk at 18 minutes per mile, it usually gets my heart rate up enough to count.

My girlfriend, who runs (and is in better shape than I!) will get no exercise counted at 18 minutes per mile - she has to walk faster.

So check out your pace - it needs to get high enough to impact your heart rate to count, and if you get into better shape you’ll need to keep increasing your pace to get your heart rate into the exercise zone.

Then I don’t have a good answer for you.

You can always go back to the earlier walks that counted and look at the heart rates recorded for those versus the most recent ones and see if there is anything different.

idk but may be related to my question -Why are my walks now divided into segments? Just started.
