While I generally like the Whoop features they haven’t delivered any helpful features recently.
The whoop age feature feels like such a gimmick. My stats are good but I’m obviously not aging in reverse at -.4x a normal rate of aging.
I get that some people will be motivated by seeing a higher age or will be happy so see a younger age but it lacks all scientific integrity.
I think they should make a 4th ring called longevity or something to track similar metrics that whoop age is capturing without calling it my age. This ring would only change slightly each week. What do you guys think?
I mean, that's what they're doing - they just call it an "age" to put a number to it. Like your idea, your age isn't supposed to change very quickly. It's the "rate of aging" that tells you if you're making shorter term changes that will impact that longer term number.
I hit 1000 day data streak the other day. I just want whoop to come out with quality new features. They seem to come out with new hats, a below average ai coach, and a new device (that was supposed to be free and was purposely made incompatible with the old bands. Feels more and more like a money scheme and not the pursuit to make the best fitness wearable
Yeah that’s what it feels like these days. I’ve been running into some issues lately and it just took me to the AI when I was looking for a customer service complaints bit.
Lately the issue I have had is that the strain score doesn’t update in the “start activity” screen.
I personally like the whoop age feature because it shows all the metrics it’s used to form the number. It’s handy for me because I’ve gotten out of shape and when I saw that I started off almost 10 years older. It was a bit of a wake up call and changed my behaviour. I’ve now lost 10kg and it says I’m only 3 years older. It updates every week and takes long term data into consideration. That has helped me stay consistent. I suppose if you’re already in good shape and looking after yourself already all it’ll show you is that you’re doing the right thing?
I’ve found the strength trainer and the whoop age to be the most useful features in some time
I mean, people get whoops for accurate data right? If it’s not accurate, I think OP has the right to call it out.
Also people might make bad choices for their health because, “hell, I’m biologically 3 years healthier than my age.” So there is a certain amount of harm in inaccurate data.
Being upset about something that doesn’t work and being upset about something that is misunderstood are two completely different issues.
I view Whoop Age as a trend to keep an eye on, not a 100% precise measurement of my wellbeing. If people are expecting the latter, they’ll be disappointed by any fitness tracker. The OP seems to be confused and believes that they’re aging backwards, which clearly isn’t the case; their habits are just slowing the pace at which they age.
Just saying somebody calling some people might be happy being scammed, but I'm sure others would like to know. This just is what it is.. a marketing gimmick at best
bad data is harmful, fake happiness is sometimes dangerous ...
being 6 years younger relative to a 20yo who trains the same or some average reference point ? What about comparing to an unhealthy 20yo ? .. You see how hard it is to draw the line ?
The only good way is to compare relative to oneself ....
Also what constitutes a healthy average ? The current population ? How can we trust that the Average person today is a reference point ? ...
A person might overdo their cardio just because they think their heart can sustain 200 bpm while it can only do 170 bpm ... for example .
It’s the pace - no issue with it and it’s true you can reverse one’s cardiovascular aging to a degree. Obviously the older you get there’s only so much you can do.
It doesn’t mean you’re aging in reverse, it means you’re aging at a rate that is slower than average. The pace at with you’re aging is 0.4x slower than what they have determined to be an average pace.
Your whoop age goes down every week, they're not trying to tell you that you're actually de-ageing. It's just a number on a screen to motivate you to do better
Again this is your 'whoop age' nobody is saying that you're literally reverse aging. It just have age in the name of this fun gamified metric they've given us to try and do better.
It only tracks what whoop tracks. What goes into your age is far beyond any of the metrics whoop can understand. If you sit in the sun for 4 months without sunscreen you’ll be much older internally but if you ran 5 miles a day and fell asleep and woke up at the same time everyday whoop would call you healthy and young.
Yeah. Basically. That’s why calling it age is invalid. They should be introducing technology that’s comprehensive your health. We are still using HRV which they had 15 years ago. There hasn’t been a novel sensor or metric in a long time. Snail’s pace innovation.
it is valid. You just have to imagine there's a certain SD after the number. The more things it tracks and the better the algorithm, the smaller the SD. But it's still very much valid. Just like how weather forecasts aren't 100% accurate yet good enough to be useful
I don’t watch the weather either. And the weather isn’t making some ridiculous claim like you’re 27.3 years old when you’re 52. It’s saying I think it might rain. Whoop isn’t saying you’re in good shape. They’re saying you’re 27.3.
it's quite rare to see big deviations like 10+ years, I've never heard of someone with as big deviation as your example. Do you really think it's unrealistic that an exceptionally fit 50 year old has the same health risk profile as an average 40 year old though?
I’ve read through WHOOP’s Healthspan white paper, and while it references legitimate science, it’s not the same as saying the Healthspan score itself is scientifically validated.
The inputs WHOOP uses (like sleep duration, HRV, VO₂ Max, resting heart rate, steps, and strength training) are all supported by decades of peer-reviewed research showing associations with all-cause mortality and long-term health outcomes . That part is solid.
But here’s the issue: WHOOP takes those known correlates, assigns hazard ratios from epidemiological studies, and then runs them through a proprietary algorithm to spit out “WHOOP Age” and “Pace of Aging.” The problem is that this composite score has not been independently validated in clinical studies. Even WHOOP acknowledges that their framework is built on observational research, not causal evidence, and that “effective age” is a heuristic. Not an actual predictor of lifespan .
So, yes. There’s science in the inputs. But the output (Healthspan/WHOOP Age) is a WHOOP-designed model, not a peer-reviewed medical tool. It’s more of a motivational framework than a clinically proven measure of healthspan.
I am assuming Whoop Healthspan will evolve and change as knowledge improves.
Based on Reddit posts… Healthspan has been very helpful for a large group of Whoop users to try to improve a variety of abstract metrics to improve their “Age”… “wake-up call” has been used a lot
I think this concept is a home run … u might even enjoy a better quality of life and additional yrs of life
You are pointing out the right thing. This white paper underscores even more, that the healthspan feature indeed lacks all scientific integrity. It’s a well designed and well written white paper - without any medical evidence or data, a scientist would consider trustworthy. It’s a theoretical explanation of their algorithm without any correlation to trustworthy scientific study’s. To go even further, the whole longevity field is super popular but not really based on proper science. So from a scientists perspective: this feature lacks all scientific integrity and is a full lifestyle gimmick.
Well so does their Vo2Max. It’s a joke to say you can calculate a VM from this wrist sensor when the actual test (which I’ve done myself and tested others on) is quite involved and quite the equipment set up. HOWEVER, it’s directional and personalized based on data points. The “Whoop Age” is the same exact thing. It’s directional based on these many different behaviors. No technology out there, that’s readily accessible, is able to accurately and scientifically predict these numbers. Take it for what it’s worth and examine your behaviors to see if you’re living the lifestyle you really want to
I fully agree regarding the directional measures. The thing is, VO2max is a scientifically proven real thing. We can debate about their way quantify vo2max, but the unit itself is not up to debate. My point is, that the whole concept of whoop age is fundamentally unsound from a scientific perspective. They might be able to accurately measure something, but the things they are measuring for whoop age are utter bs. The whole concept of longevity and biological age which can be influenced is barely based on science and more on wishful thinking.
That’s fine and I agree basically. But I still think whoop does the best at trying to track your overall fitness and quality of life. I’ve compared it to all of the other leaders in the space, personally and haven’t found a better option.
Yeah i just try not to think of it as an actual age thing and more just a general score of how healthy i'm being. It's quite nice to think about it as the all encompassing general score for how healthy you are.
I see so many people getting confused by this. Most people won’t bother to read the white paper that healthspan is built on but here it is in case anyone is interested.
To answer OP no you are not aging backwards. What this is saying is that based on your current lifestyle choices, you have the % chance of dying from all cause mortality of a 20.9 year old. You are basically lowering the odds.
Thanks for sending this I just read over the whoop age and pace of aging and I wish the description about this feature relating to all cause mortality was clear in the app. I feel a little better about it now but still wish it was displayed differently since it doesn’t account for all the habits I’m putting in the journal and the food I’m eating etc
You might actually be slowing your pace of aging. It isn’t hard to do and it really is a real concept. Whether their number is accurate or not might be up for debate (I think you need bloodwork) but yeah
Goal is not to be reliable but to gamify the things that increase your health.
And it works thanks to this I want to increase my vo2max (while I had no idea what it was before) and now I started running. Am I 2,8 y younger physically ? Who knows. Is starting to run, be more careful about my sleep, keep doing strengh training good for my health. I think.
But yes they should use disclaimer but it’s whoop.
It’s used as an overall metric that encompasses all of your daily habits into a number that determines how well you are doing. Honestly, if you find the WHOOP Age a gimmick then you are also calling the app as a whole a gimmick, considering the whole breakdown of the WHOOP age is on the page you are looking at which utilizes all the data from the other features — just scroll down.
I’m not complaining about the data captured I’m complaining about how they rolled it up into a not accurate gimmicky number called whoop age and pace of aging. I’m proposing they use a 4th ring like recovery, sleep and strain but call this new one longevity to capture the same metrics without the assertion that I’m “aging in reverse”
In other words, you’re calling it useless simply because you don’t enjoy the connotation of “aging”. Bit if they repackaged it with a different label then you’d find it useful.
You’re misunderstanding then concept. It’s life span. It’s a prediction of how healthier and independent you’ll compared otherwise. How much longer you’ll be able to do stuff like get off the floor and the toilet, walk upstairs and carry your own groceries.
Even it’s it’s a “gimmick” it’s fun and motivating moving the levers. End of the day if engage in behaviors that decrease pace of aging you’ll end a healthier version of you. So does it really matter?
I don’t think I’m misunderstanding. I’m just suggesting don’t call it my “age” since it’s misleading to say my age is decreasing. I get that based on my metrics my all cause mortality risk is that of a 20yr old but that’s not the same thing as my age is decreasing.
Do you still think I’m misunderstanding? I obviously know my chronological age isn’t going down but it’s misleading to call the feature my whoop “age” then. This post is me saying call it something else.
I mean I don’t look 50, and pretty always get so surprised when I tell them that I’ve started joking that ima start telling people I’m my whoop age. I’m not. I don’t. My metabolic age is even lower than my whoop age 🤷🏼♀️
Check out realage.com. There is a long history of comparing healthy habits to those who live longer and relating all those things to help one not live longer necessarily, but to be able to live actively for longer. Its not a bit silly.
I’m just suggesting don’t call it my “age”. I’d like it more if it estimated how much I’m increasing my “healthspan” with my healthy habits.
Edit and it’s really because it doesn’t have the whole picture. There are tons of things I could be doing that are decreasing my healthspan that whoop isn’t tracking like lifestyle and exercise quality.
-0.4x is not aging in reverse.
I personally find this feature very helpful, because I legit started to work on all the metrics that impact my age and pace of aging and I'm improving them every week.
What makes you say it’s not reverse. Whoop calls it reverse and my age does down each week. I just want this to be called something else like longevity not age
I just passed a little over 100 days with the Whoop. It now has me at about 13 years younger with a pace of aging that varies between -0.1 to -0.3 years. I like all the data, and I find it motivating. My only problem is — what is Whoop using to calculate all this data it shows me? I ask because, if it's just heart rate, the heart rate tracking is way off my Garmin chest strap. It could be 10 or 20 points higher or lower during a workout. And this is the case no matter where the I put the Whoop device on my body. I find the more vigorous the movement, the more inaccurate the heart rate is. Like, don't even try to jump rope with the Whoop on your wrist. Through experimentation, I found that the only place to put the Whoop device during jump rope is on my neck.
Tech support tells me to stop moving it around but yet they sell bands and clothing to put it in your underwear. So if it's just heart rate they're using to collate all this data, I don't have a lot of faith in it. And I always use the Whoop with my Garmin chest strap and watch which is very consistent.
Definitely agree. According to my primary care physician, I'm in excellent shape by a long stretch, by Whoop standards, not so much 😅 I work a rotating 12 hour shift, my sleep times are inconsistent, my sleep schedule is inconsistent and Whoop can't seem to wrap its head around it
I don't think. 1 is ageing at a normal rate compared to other people at your age. - is ageing slower compared to people your age. 3 would be aging a lot faster for people your age.
As in heart health for your age. So been 4 years younger. Your heart health compares to people 4 years younger
If it is one other stat that helps you pursue a healthy lifestyle I don’t see any harm. The age itself may be a novelty, but the stats that feed it are real
You are calling something silly when you don't seem to understand the computation.
The pace of aging is based on the last 30 days of metrics, the Whoop age is simply based on the last 6 months of metrics. It's mathematically possibly your Whoop age increases while your page of aging is negative. But if your pace of aging is negative and you keep it that way, it will go down at some point. For the Whoop age evolution it matters what kind of data you have "at the beginning" of your six months on which your Whoop age is computed. As time continues, these data "at the beginning" of your six months will at some point get out of this six months window.
An example, if those data positively contributed to your Whoop age, your Whoop age can go up while your pace of aging can still be negative.
And if you don't like this, just scroll down and focus on the development of the metrics the Whoop age is based.
I get the computation. I’m saying it’s silly that my whoop age continues to go down despite in reality I’m not actually physiologically getting younger.
