VO2 max

My advice would be: don’t pay attention to the vo2max your watch calculates. It isn’t very accurate.

If you want a better feeling for your vo2max do a coopertest once in a while or do a test in a sport medical center.

(but probably not the advice you’re after ;)

I would suggest that you reduce your maximum heart rate in the Heart Rate Zones and it will begin to update again. It will probably start with a reduction but while I agree that it is not a lab test, it does provide guidance on your improvement once it is updating.

Thanks will try that

Thanks anyway
