I've been walking 3.5 miles a day since Feb 2021 and watched my V02 Max level fall to 35 (fair).
When I load Garmin Express on my PC and select vivomove HR it loads Garmin Connect and displays a picture of my wife's watch (who doesn't exercise) which I bought for her birthday in Feb 2021.
How do I know which watch my VO2 Max level is coming from?
