Achievable Fitness Age

Very interesting. I was also 20 years old before the change and is now 35.5 years old and my real age is 44. The old estimate didn't sound that scientific. If you read the help pages in the app or the web you will get an overview in how it works but not the algorithms for it.

I only find this when I search for it: https://www.firstbeat.com/en/blog/whats-your-fitness-age-vo2max-reveals-it/

I can cut 0.5 year if I reduce my BMI and for that I need to lose 1 kg. For me that is not a good idea since I'm not just a skinny runner, but a multisporter that also need some upper body muscles. It is more likely that I will gain 1 kg when I start to focus on my upper body.

Yeah, I read all the "help" but looking forward to more info from Garmin.  My guess is that your achievable fitness age is now your current age - 9, based on a sample size of 3 (someone in their 20's, 40's and 50's)  .

I'm 55 with a fitness age of 48.5 & VO2m of 50.  Mine fitness age too previously stated 20yrs old.  The new number at least seems more realistic.

Exactly the same for me. And the “lower your BMI to gain 0,5 years” as well.

Strange to rearrange all of this without any explanation.

I've just been searching for this and came here to see if this thing is new. I've reached my archievable age which is 9 years younger than me. It seems a bit of a meagre achievement I must say. Mine is from a Garmin 945. According to my data, it seems to have been implemented on April 20.

Haha - I‘m 73 and I‘m on VO2max 42.
Until last week my fitness age was about 45.  (many thanks to Garmin!)
Now it is 38!  

I agree. Most of us are in good shape, but that doesn’t cut your age by more than half. The new methodology seems to arrive at a more plausible “fitness age” though it is odd that they seem to have removed vo2 Max from the calculation. You’d think it would still be a factor alongside the new variables. 

It begs the definition of what would be a good comparative. It's really pointless comparing yourself with the average couch potato, which I guess was what put us all at age 20. It's more meaningful to compare with people who have at least a certain level of fitness. So perhaps I'd like to compare myself to everyone on garmin connect who runs more than 30km a week or cycles more than 150km/week, or perhaps does more than 5 hours a week of cardio exercise, say.

Hi :) I also reacted to the new calculation of fitness age. However my main concern was that the app recommends me to drop to a BMI of 19.8. Thats in the lower end of the healthy scale.. For me that means a drop of almost 10 kg. Is this okay to recommend people? I am fine with my weight! and I know that a BMI of 19.8 would mean I would look extremely skinny, and not healthy. My concern is that making these very strong recommendations is completely unneccesary. I am a woman of 39 years, so I am comfortable with my weight (sounds like I'm fat.. but I am not ;) ) I have a VO2 max of 46 according to Garmin, but I am going for long distance not speed, so thats fine.. A lower weight wouldn't make me healtier. Faster, yes, but not healthier..

This can become a real problem for some people. 19.8 is still in the healthy part of the scale and I guess that is why it can be recommended by the algorithms, but that doesn't mean it is healthy in reality. This is the problem when you let a computer do the recommendations and statistically it is probably perfectly correct that you will live longer if you loose that weight, but statistics is statistics and don't take everything into account.

I think it would be a better idea if the algorithms would aim for the middle of the healthy scale: 21.7
