Why do my sport age or vo2max not update at all. I get regularly fitness points, but my fitness age

JyRa

is all the time at 22 and my vo2max stays at 44.

It uses your calculated VO2Max (which will be wrong as no watch can compute this) to calculate points and it only uses runs or cycles. It is not the amount of exercise that matters, it is the intensity. Unless you are in Z3 or higher for a substantial part of your workout it will not change anything. If your workouts are walks or jogs or anything that is not intense, it will have no impact on the age and points. It is based on whatever algorithm TT came up with, which is different than what Garmin uses or Strava uses, or anyone else. I honestly don't feel you can make any judgments from what it is telling you in terms of fitness points or fitness age, it seems to be a random, capricious measure that ties to very little. Ultimately, I don't expect a watch to be able to tell me how fit I am.
