Just when we thought WHOOP had already nailed the wearables game, they’ve gone and dropped a powerful update with the release of WHOOP 5.0—and it’s not just about the hardware.
Yes, the device itself is now smaller, lighter, and sleeker, but the real story is what’s happening under the hood (or rather, under the strap).
The standout feature? Two new healthspan metrics—WHOOP Age and Pace of Aging. Together, they aim to answer a question most wearables ignore: How is your body aging over time?
Let’s break it down.
WHOOP Age: A Mirror to Your Long-Term Wellness
First things first, WHOOP Age isn’t about guessing how many candles should be on your birthday cake. This number is calculated using six months of your sleep, recovery, and strain data to estimate your body’s “effective” age. Think of it like a report card for your lifestyle choices.
Here’s the kicker: it’s not easily swayed by a few bad nights or missed workouts. It changes slowly—on purpose. WHOOP designed it this way so you focus on building healthy habits, not obsessing over daily fluctuations.
So, if your WHOOP Age reads younger than your real age? High five—you’re doing something right. Older? Don’t panic. It’s just a nudge to rethink your rest, movement, and stress management.
Pace of Aging: The Weekly Weather Report for Your Health
While WHOOP Age shows the big picture, Pace of Aging gives you a week-to-week status update. It looks at your last 30 days and compares that trend to your six-month baseline.
It basically asks: If you keep going like this, will your body age faster or slower?
So if your recent sleep’s been patchy or your workouts fell off a cliff (no judgment—we’ve all been there), your pace may speed up. On the flip side, dial in your routine and you’ll see your pace improve.
Both metrics live under the new Healthspan section in the WHOOP app. Each week, you’ll get updates and personalized tips to help you steer your WHOOP Age in the right direction.
What Goes Into These Metrics?
WHOOP hasn’t kept this a secret—there’s a transparent recipe behind the magic:
Sleep
- Total hours of sleep
- Sleep consistency
Strain
- Time in heart rate zones
- Strength training time
- Daily steps
Fitness
- Lean body mass (tracked via compatible smart scales like Withings)
- VO2 Max
- Resting heart rate
It’s a lot more holistic than the old “calories burned” model most wearables use.
Oh, and in case you’re new to WHOOP—you’ll need to record at least 21 sleep or recovery sessions in your first month to unlock Healthspan. From there, it calibrates over 90 days, and you’ll continue to receive weekly updates if you stay consistent.
Not Available to Everyone—Yet
There’s a catch: these aging insights aren’t unlocked for everyone. If you’re on the WHOOP One entry-level plan or using a 4.0 trial, you won’t see these metrics.
But full WHOOP 4.0 members might get access soon. The company has hinted at it, saying that Healthspan isn’t available on 4.0 “Trial”, leaving the door open for full subscribers.
For now, WHOOP Age and Pace of Aging are included in the Peak and Life tiers—so if you want them, you’ll need to upgrade.
What Else Is New With WHOOP 5.0?
Besides the fancy new metrics, WHOOP 5.0 brings:
- Improved sensors
- A more compact and lighter design
- A water-resistant Power Pack for seamless charging on the go
And the subscription model is now clearer than ever:
- WHOOP One: $199/year (core tracking only)
- WHOOP Peak: $239/year (adds WHOOP Age, Healthspan, VO2 Max)
- WHOOP Life: $359/year (everything in Peak + ECG & blood pressure insights)
The hardware comes included, and current users can upgrade to 5.0 by renewing or paying a flat fee.
Final Thoughts: A Smart Shift in Fitness Tracking
Other brands have toyed with the concept of biological age—Garmin’s Fitness Age comes to mind—but WHOOP takes it up a notch.
By combining long-term health insights with short-term trend tracking, it’s helping users zoom out and actually understand their health trajectory, not just their daily stats.
For anyone who’s ever thought, “I’m working out and sleeping okay, but am I actually getting healthier?”—WHOOP 5.0 just might have the answer.
