Peak Health guides the plan. DexaFit measures the proof.
Peak Health builds proactive, data-driven care around each member. DexaFit adds the measured baseline that plan runs on, DEXA body composition, VO2 Max, and RMR, so progress is tracked in real numbers, not estimates.
Redeem your Peak Health code for DEXA, VO₂ Max, or RMR testing at a DexaFit location near you. Results read with you the same visit.
Three clinical-grade tests, one visit
DEXA Body Scan
Fat, lean mass, and bone, region by region. See exactly where to put the work.
VO₂ Max Test
The strongest predictor of how long you will live, measured directly, with your training zones.
RMR Metabolic Test
The calories you burn at rest, measured not estimated. The base for any real nutrition plan.

Built for every body and goal
Drop the fat.
Hold the muscle.
The number went down. Which weight actually left?
- The scale rolls fat and muscle into one figure. A DEXA scan separates them, down to the pound.
- On a GLP-1, up to 40% of what you lose can be lean mass. You will see exactly where yours is going.
- Smart scales run 8 to 15% off on body fat. A DEXA scan is the clinical gold standard.
Six months in, you will know whether you lost the right weight, not just weight.
Train with precision.
Confirm it worked.
Close enough leaves gains on the table. Read your real margins.
- VO₂ Max sets the ceiling on your output. Your wearable estimates it. We measure it.
- Lean mass comes back broken out by arm, leg, and trunk, a level of detail no scale or band reaches.
- RMR shows what you burn at rest, so you fuel the work off numbers instead of hunches.
Six months in, you will know whether the work built muscle or only shifted the scale.
Your body is shifting.
See what is driving it.
The changes that count most stay out of sight.
- Menopause pushes fat inward, toward the organs. The mirror misses it. A DEXA scan records it.
- Bone loss accelerates around menopause. An 8-minute scan hands you a number to act on.
- Metabolism shifts through perimenopause. An RMR test shows you by how much.
You stop guessing whether it is hormones or habits, and start seeing which.
Stay strong, sharp,
and steady.
The numbers that decide how strong you hold past 40.
- You shed 3 to 8% of lean mass per decade after 30. A DEXA scan follows it region by region, so you know what to defend.
- Visceral fat sits deep around the organs, where the mirror never reaches. A DEXA scan measures it directly.
- VO₂ Max and resting metabolism set how you train and how you eat. Both read straight, not off a watch.
At 50 you will know what you kept, and what it took to keep it.
Longevity begins
with one number.
Wearables read the signal. We measure the structure beneath it.
- Visceral fat is tied to cardiovascular risk, and BMI cannot see it. A DEXA scan reports it in pounds.
- Across 122,007 adults, VO₂ Max tracked with mortality more closely than smoking or diabetes (Mandsager et al., JAMA 2018).
- Every retest measures you against your own history, so the picture sharpens visit by visit.
In five years you will hold a trend line, not a memory of how you used to feel.
No goal yet?
Start with a baseline.
One test, and the guessing about your body is over.
- No goal needed. A single baseline makes every health decision after it clearer.
- Routine checkups leave gaps. We fill them with numbers your doctor can put to work.
- Start here. Training, nutrition, and goals fall into place once the baseline exists.
You will have a starting line instead of a guess about where you stand.

Questions, answered
How do I redeem my code?
Click Get DexaFit Now, enter your code, choose your tests and a location, and book. If your code was sent as a link, it may already be applied for you.
What is the most accurate way to measure body fat percentage?
A DEXA scan (dual-energy X-ray absorptiometry) is the clinical gold standard for body fat percentage, accurate to within about 2%. Scales, calipers, and impedance devices only estimate and can run 8 to 15% off, and none can read visceral fat. DEXA measures fat, lean muscle, and bone directly, region by region.
Is a VO₂ Max test worth it for me?
Yes, for almost anyone. VO₂ Max is the single strongest predictor of long-term health, with a 5x mortality gap between the least and most fit (Mandsager et al., JAMA 2018). We measure it directly rather than estimating it from a wrist sensor, and it responds to training at any age, so your number works as both a target and proof your training is paying off.
How do I accurately measure my resting metabolic rate (RMR)?
The accurate way is indirect calorimetry, a short breath test that measures the oxygen your body uses at rest. Online calculators only estimate RMR and can be off by 20 to 30%. An RMR test measures your real number in about 15 minutes.
Do I need a referral or any preparation?
No referral needed. Each test has simple prep, and the full details are on our pre-test protocols page.
When will I get my results?
The same visit. A specialist walks you through every number against age and sex matched ranges, and your results are saved in the DexaFit ai app so you can track them over time.
Which tests can I book with my code?
Depending on what your code or prepaid order covers, you can book a DEXA body composition test, a VO₂ Max test, an RMR metabolism test, or a combination. VO₂ Max and RMR are not available at every location, so availability is shown when you choose a location.
