My VO2

Why is there no VO2 max data in the Health app?

If you can’t find any VO2 max readings in the Health app, that is probably because you have not yet logged the right kind of workouts with your watch. Only three workout types can produce an estimated VO2 max on Apple Watch: Outdoor Walk,Outdoor Run and hiking.

VO2 max relates to maximal exertion. So you’ll need to log a pretty intensive workout to generate a reading. And you’ll need to sustain it for at least 20 minutes.

I have a series 5 and can’t get vo2 readings. I use to get them on my series 3 but once I upgraded to series 5 it stopped. I use the outdoor walk in workout app that comes with the watch and it still doesn’t display any information.
