Cardio fitness not being recorded

Health app has stopped recording Cardio fitness. That's it. I used to get a reading for cardio fitness from my Watch after every outdoor walk and outdoor run but they seem to have stopped on 19 September. Nothing has changed, as far as I know.


How can I fix this so I get cardio fitness readings again?

This can happen if the Watch stops getting the heart-rate/GPS data needed for the estimate.



Check these first:

  • Health ->Profile -> Devices -> Apple Watch ->Privacy Settings ->Fitness Tracking = ON.
  • Watch app ->Privacy ->Heart Rate = ON.
  • Make sure Location Services and Motion Calibration & Distance are ON.
  • Try a 20-minute Outdoor Walk or Outdoor Run with a good GPS signal and the Watch fitted snugly. Apple says this helps recalibrate the Watch.
  • Then check Health ->Browse ->Heart -> Cardio Fitness.


Apple says Cardio Fitness estimates require an Outdoor Walk, Outdoor Run, or Hiking workout and can take several workouts before an estimate appears.



If it stopped completely on September 19 despite everything working normally, I'd also restart both devices and check for any pending software update.

Thank you. I had tried all of those, and software is all up to date. I restarted the phone after the most recent software update. I will try restarting the watch too.
