Despite seeing very solid progress, my watch keeps reporting that my overall training is "unproductive", and after each session it concludes that my VO2max has "worsened" (despite also reporting that the run had a positive effect on it).
#Garmin, you're supposed to cheer me on and not punish me for getting my butt out the door! 😂
This seems to be a well known issue among users. The training status metrics apparently don't reflect reality at all.
