Has anyone else’s cardio fitness score suddenly drop? 

Mine was consistently in the very good to excellent section for two years then suddenly this week, it dropped to poor. This literally happened over night and I have no idea why!!

@Rkatiec A warm welcome to our Community! Sorry for the delay in my response.

Let me help you with your Cardio Fitness Score. Have you changed your routine or activity level recently? Or have you stopped wearing your device during the day or night? Still you could log some run or walking activities to help it update. You can read more about it here.

Let me know how it goes.

I have had the same thing happen to me my score has fluxed between 40 and 44 and in the last week has dropped to 21. No change to my exercise routine or resting heart rate. I would like to know what is wrong too.

Mine has just done exactly the same. Did you get to the bottom of why?
