Achievable Fitness Age

Garmin seems to have completely changed the way fitness age is calculated and displayed in both GC Web and the GC Android app (at least for me).  Last time it looked, my fitness age was 20 and calculated from my VO2Max.  Now it is way, way higher, and uses resting heart rate, weight and activity.  It says I've reached my "achievable fitness age".  The historical data only shows the last four days, so I am assuming this changed in this week.

I can't find any information for this new way of calculating data.  Can anyone shed more info or provide links to a white paper or blog entry?  Garmin is normally pretty good at providing  explanations on their information.  E.g. how is the achievable fitness age calculated?

I am also assuming it is related to the new Venu 2 release this week.  The only Google hit I got on achievable fitness age was in a Venu 2 review (with no explanation).  Nothing has changed on my side.  I've been using the same devices for the last 18 months or so.

  • It appears that it recommends a lower BMI if you don't have a body fat % reading (or your have both). When I upload my weight and BF% it gets sent to myfitnesspal which adds my BMI and sends the record back. I usually delete that second weigh-in. Before I delete it, it recommends my lowering my BMI, but after I delete it, it gives me all three ticks based on my BF% being ok.

  • I don't think it should make recommendations about weight/BMI at all. We know this is not a good measure of health at the individual level. Many very fit athletes have high BMI. Also a lot of young athletes struggle with body image, so to me this seems very old school.. "get skinny, run fast!" ;) If people want a weight target, they can set that themselves :) Not having Garmin picking a random superskinny number..

  • I'm not see an 'achievable fitness age' in Garmin Connect Web (Version: 4.42.1.2, 21.8.5.0) or Garmin Connect Mobile for Android (Version 4.42).

    In Garmin Connect Web I'm still 20 with no mention of 'achievable fitness age'.

    In Garmin Connect Mobile for Android I'm 29 (why the difference?) and the link to Fitness Age at the bottom of the page in not present.

    I use a fēnix 6X for running and walking activities and a Edge 1030 Plus for cycling activities if that makes any difference.

  • Real age 60......VO2max age is now 20......Yes I am good...no I am not that good!

  • That is probably why Garmin implemented Fitness age instead of the old age calculation you got there. I guess everyone with a high VO2 max will get the age 20.

  • It is under Healthstats on my Connect app.. But it's not in my husbands app, so I don't know if maybe there are differences with different watches? seems strange. 

  • Do you have Blood Pressure listed under Health Stats too? From the few screen captures I have found, you appear to either have them both or neither of them.

  • I have fitness age, but not blood pressure. I think it's whether you have a certain type of watch, such as the venu 2, garmin 945 or a select few that got the fitness age update recently.

  • I'm not aware of any Garmin watch that measures blood pressure.

  • I have a fēnix 6X which has a check mark on the specification page for Fitness Age with '(In App)' beside it, so in theory supports Fitness Age.

    In you your earlier post it sounds like you have the option to input body fat percentage. I don't have that either.
