I have my settings set so that my activity tracking is done automatically. It registers when I go for walks and tracks it, but I just noticed that my VO2 max hasn't been calculated during the walks.
Do I need need to start the VO2 max when I begin a walk? I thought it would be done automatically as per the manual "If you have already recorded a 15 minute brisk walk, your VO2 max. estimate appears. The device displays the date your VO2 max. estimate was last updated. The device updates your VO2 max. estimate each time you complete a timed walk or run".
