Fitness age vigorous minutes seems incorrect.

In the Garmin app under Fitness age it gives my 4w average vigorous minutes as 56.5. This appears to be reading far too low as my actual average (under intensity minutes) is 13 average daily (so 91 a week) over 4 weeks. Why this big discrepancy? As a consequence the fitness age calculator Is telling me I need to increase fitness minutes but I am already doing 91 a week. Is it possible there is a bug in the Fitness age vigorous minutes calculation? Any help to resolve this is appreciated. Thanks a lot.

    Because for the Fitness Age (unlike for the IM stats) there have to be minimally 5 continuous vigorous minutes for them to be counted.

    Ah I see so if you are running and for whatever reason your intensity drops during a given 5 mins period the fitness age doesn't count it but the IM does. Is there a reason for this that you know of?  Many thanks for your reply.

    Certainly there is one, but I do not think that Garmin published it. Probably they want to avoid taking in account just random HR spikes during the day, possibly caused just by a dispute with your wife or boss Rofl

    This has also been an issue for me since about September or October. I worked really hard to get my vigorous minutes average up and what it shows on the home page is over 75 minutes a week while in fitness age it’s often only 48-52min. I hike so it’s hard to always stay in vigorous zone if the elevation changes, so if they have changed so it only counts when it’s a five minute chunk, that would explain the discrepancy. I brought it to their attention a while ago, and they were supposed to look into it but I never heard back

    So did you find that the problem was how you had set the vigorous minutes setting? What did you change it to to fix it?

    Go to watch settings -> health and wellness monitoring -> goals section, vigorous minutes

    Switch zones off and should be fine

    From what I'm seeing over the last few days, there is a miscalculation with this stat that reduces it by 1/3. It appears to be calculated as follows:

    Avg Weekly Vigorous Mins = (4 week Vigorous Mins total) ÷ 6

    For example, I have 86, 74, 21, and 28 vigorous mins over the last 4 weeks. That's a total of 208 mins, or 52 per week. Fitness Age instead shows 34.6 mins per week, which happens to be 208 ÷ 6 (decimals beyond the first truncated).

    I've tracked this for about a week now, and it's always calculated the same way. Does anyone know where this bug can be reported?

    No, there is no miscalculation. If you read the thread, it is explained here how Garmin calculates it  - minimally 5 continuous minutes are required before it counts for the fitness age (unlike at the plain IM stats). Individual separated vigorous minutes do not count (which makes the sense).

    I've been tracking mine recently. Both appear to be roughly 60% off. I've been taking care to have at least 5 minutes continuous vigorous in a workout I want to count towards the Vigorous Day count. I should be at 4.5 but I'm at 2.6. I've been sitting at 2.5 or 2.6 and after I workout for the day it jumps to 2.8.

    My weekly minutes should be at 80.3 but are at 53.5.
