Over the past few months, I’ve been making some big changes to my health, fitness, and lifestyle — and honestly, it’s been one of the most rewarding projects I’ve ever taken on. One thing that’s kept me motivated is my “Health Stack”: the collection of devices I use to track progress, get insights, and sometimes just geek out over the data my body produces.
If you’re curious about what’s been working for me (or maybe looking for a nudge to start your own health journey), here’s a breakdown of my stack — what I use, why I love it, and how it all fits together.
Body Measurements and Tracking
Withings Body Comp
Regular Price $229.95
This is my daily go-to scale. It does more than just measure weight — it also calculates body composition (fat % and muscle %), and it syncs seamlessly with Apple Health.
I used to have the Withings Body Smart, which is a fantastic entry-level option, but I upgraded to the Body Comp for its extra features like nerve health measurements. Honestly, for someone my age and fitness level, nerve health isn’t a big concern, but it’s nice to know it’s there.
The coolest part? I’ve compared its results against the big, expensive body composition machines at my gym — and the numbers line up almost perfectly. Plus, you can set it up for multiple users, so the whole household can join in.
Renpho Smart Tape Measure+
Regular Price $59.99
This is a new addition for me, and I love it. Sometimes, even if the scale shows progress, you don’t always see the difference in the mirror. The Renpho tape measure helps me track actual inches gained or lost around my chest, arms, and waist — a very motivating reminder that small daily choices really do add up.
Fitness & Activity Tracking
Fitness trackers are incredible tools for capturing the data that actually matters when you’re working to improve your health. Most will give you heart-based metrics (resting heart rate, workout intensity, recovery), GPS tracking for runs or walks, and even estimates of strain during weight training. But here’s the real game-changer: when you’re trying to lose weight, a tracker helps you get a much more precise picture of your daily active burn. That number is key for managing caloric deficits in a sustainable way. Instead of relying on a generic TDEE estimate, you can calculate your actual burn day-to-day and make smarter adjustments.
Whoop
$159-$359 Per Year
Okay, I admit it — I splurged on the fancy Whoop MG. But no regrets. Whoop takes a strain vs. recovery approach, using continuous heart rate data to give incredible insight into how hard you’re pushing your body and how well you’re bouncing back.
Unlike trackers you have to charge daily, Whoop has a genius clip-on battery pack that lets you charge it while still wearing it. That means it can truly be worn 24/7, collecting a mountain of data on your heart, sleep, recovery, and workouts. It also plays really nicely with Apple Health, Withings, and Strava (which I use to keep myself accountable).
The bottom line: if you love the idea of maximizing your workouts and your rest, Whoop is worth checking out.
Apple Watch Ultra 2
Regular Price $799 and up
Even though Whoop is my main tracker, I still use my Apple Watch Ultra 2 for specific workouts — especially treadmill runs, since Whoop doesn’t calculate distance indoors.
If you’re not ready for Whoop’s monthly subscription, an Apple Watch is an excellent choice on its own. It integrates beautifully with Apple Health and Apple Fitness, tracks everything you need, and has tons of extra features for everyday life. The only downside? You’ll need to take it off daily to charge.
Heart Health
Heart and kidney health have been top priorities for me. Kidneys mostly require lab work and doctor monitoring, but for the heart, I’ve added a couple of powerful tools for peace of mind.
AliveCor KardiaMobile 6L
Regular Price $129
This tiny gadget (smaller than my palm!) is basically a personal ECG. Place your fingers on the sensors, and it records a 6-lead electrocardiogram in 30 seconds. Results sync with the mobile app and can be exported as a PDF to share with your doctor — or just to geek out over. It also syncs with Apple Health.
Withings BPM Connect
Regular Price $129.95
When I want to check my blood pressure, this is the device I trust. It’s wireless, simple, and logs everything in the Withings app, which syncs directly with Apple Health. Multiple users can set up profiles, which makes it family-friendly, too.
For Curiosity and Learning
Dexcom Stelo
Regular Price $99 for 30-day Supply
This is probably the most fascinating piece of my stack. Dexcom Stelo is a continuous glucose monitor (CGM) that tracks my blood sugar every 5 minutes via a tiny catheter. It’s painless, and the data has been eye-opening.
What I’ve learned:
- Some foods I thought were “safe” actually spike my glucose.
- Exercise changes everything — sometimes my body even delivers an emergency sugar burst during intense exertion.
- Cutting carbs and sugar has a huge effect, but your body still has some clever tricks to fuel you when needed.
For me, the Dexcom has been more about curiosity than medical necessity. It’s a reminder of just how dynamic and amazing the human body really is.
Wrapping It Up
My Health Stack isn’t about obsessing over numbers — it’s about using data as motivation. These tools give me a way to see the invisible changes happening inside my body, which makes the hard work of eating better and moving more feel real and rewarding.
If you’re starting your own journey, you don’t need all of this at once. Even just an Apple Watch or a Withings scale is more than enough to kickstart your progress. For me, having this stack has made the process fun — like I’m running my own personal health lab.
And honestly, that’s the biggest win: staying curious, staying encouraged, and stacking up little wins every day.
