What People Say
Trusted since 2011 as the gold standard for body composition, fitness, and metabolic testing worldwide.

"I love that you can get your dexascan, resting metabolic rate AND a proper VO2max test all in one place. This is my third time there and I love it!"
"Laura was very chill and kind but still very efficient. This was my second Dexa scan and VO2 max test to track fitness and body composition. I'm an endurance athlete who wants to track progress year to year."
"I've gotten a VO2 max test done here two years in a row. 10/10 experience all around. I'd recommend DexaFit Nashua to any runner looking to improve and gain true insight about their fitness."

"My wife and I are older and concerned about our longevity. We both had scans today. I would recommend this to everyone, especially if you are concerned about maintaining or improving your health."
"VO2 max and muscle mass are both significant predictors of longevity and healthspan. If your provider doesn't order these tests for you (most don't), it's worth it to visit DexaFit to get your numbers and see where you stand."
"My first visit was a 10/10. The owners both involved in counseling me along the way to make sure everything went just right. I'm psyched to make meaningful improvements and head back in next year."
"The reports afterwards were comprehensive and educational. Great baseline information at a price that makes it manageable to return for progress reports. There was NO pressure to buy things."
"My numbers improved in all areas. It was so empowering. The way the numbers are aggregated into a combined score is equated to a 'biological age.' I certainly enjoyed getting younger!"

"Doctors wanted to put me on osteoporosis medication when I was in my 40s, no way was I doing that. My bone density has improved! I will be adding this into my health plan."

"I have been on a GLP-1 for several years and having the DEXA scan is a great way to maintain progress and keep up muscle mass. Laura was super helpful and encouraging."

Quick Answers
Booking is preferred at every DexaFit location. Each appointment is dedicated time with the equipment and a technician walking you through your results, so the schedule fills up fast. Use the map above to find the nearest location and book directly on their page.
We're expanding fast and add new locations every month. If you don't see your city yet, join the interest list and we'll notify you the moment DexaFit opens nearby.
For most tests: wear comfortable clothes you can move in (no metal zippers or underwire bras for the DEXA scan), avoid heavy meals 3 hours before, and skip intense workouts the morning of your visit. Your location will send you specific prep instructions when you book.
Yes. DEXA scans, VO₂ Max tests, and RMR metabolism tests are typically HSA and FSA eligible. We can provide an itemized receipt for reimbursement. Check with your plan administrator if you'd like confirmation before booking.
Of course. Many of our locations are friendly to partners, family members, and friends who want to wait or come along for moral support. Some clients also book back-to-back appointments so they can test together. Just give your location a heads-up when you book.
Most people return every 3 to 6 months to track meaningful change. Body composition shifts slowly, so testing more often than every 90 days rarely adds new information. Your first visit becomes your baseline, and every follow-up shows the trend.
Most of your health data is a guess. Wearables estimate, calculators approximate, the scale hands you one blunt number. DexaFit measures. In a single visit you get a clinical-grade DEXA body composition scan, a VO₂ Max test, and an RMR metabolism test: the real numbers underneath your strength, your metabolism, and your longevity. That's your ground truth. Everything else gets calibrated against it.
If you take your body seriously, DexaFit is for you. You may have first heard it from Tim Ferriss in The Four-Hour Body, seen DexaFit featured on Netflix's You Are What You Eat, or read about it in the longevity books and podcasts you already follow. It's the same gold-standard technology NASA uses to monitor astronauts and elite athletes use to stay on top of their sport.
Because these numbers can't be faked, and they keep each other honest. A lab value can be normalized in a week. Body weight can be cut overnight. The right drug or supplement can drive fast weight loss, or quick gains in muscle and strength. But a shortcut almost always costs you somewhere else: lose weight too fast and lean mass goes with it; chase size and strength and visceral fat creeps up or your VO₂ Max slips. Real progress moves the metrics that matter most, lean mass, visceral fat, bone, and VO₂ Max, in the same direction at once. Move them together, and you didn't game a result. You built something that lasts.
DexaFit started in 2011 with one goal: take the clinical-grade testing that lived inside hospitals and put it in the hands of everyone serious about their health. Today it runs across four continents and 40+ states. Wherever you go, the test, the app, and your numbers go with you. Read the full story →
Where you truly stand. Your lean mass and where it sits. The visceral fat wrapped around your organs. Your bone density. Your VO₂ Max, the single strongest predictor of how long you'll live. And the labs underneath it all. Not a wellness score or a vibe: the actual numbers that decide how strong you stay and how long you last, with personalized targets to move them.
The clearest picture of your body you'll ever get. A DEXA scan separates fat from lean mass from bone and maps each one region by region, at ±2% accuracy, the clinical gold standard. Two people can weigh the exact same and be built completely differently, so the scale was never going to tell you who you are. DEXA does, and shows you exactly where to put the work. About 8 minutes, fully clothed, results the same day. Read more about the DEXA scan →
VO₂ Max is how much oxygen your body can actually use, and it's the single strongest predictor of how long, and how well, you'll live: stronger than smoking, blood pressure, or cholesterol (Mandsager, JAMA 2018: 122,007 patients, a 5× mortality gap between the least and most fit). Your watch estimates it. DexaFit measures it directly, then hands you the real number and the zones to train against. Raise it, and you add years. Read more about VO₂ Max testing →
Your metabolism is the number every diet and calorie target is built on, and most people are working off a formula that's a guess, off by 20% or more. That's why plans stall and "eat less" stops working. DexaFit measures your real metabolic rate from a few minutes of quiet breathing, so you finally know how much your body burns and can eat for the body you actually have. Read more about RMR testing →
Yes, two ways, and they're not the same. Every total-body DEXA scan includes whole-body bone density, with T-score and Z-score across spine, hip, and total body. That's where most people start. For a deeper look, select locations offer DexaStrong, a site-specific scan of the hip, lumbar spine, forearm, and wrist, built for anyone serious about osteoporosis risk or fracture prevention. Bone loss is silent and starts earlier than most expect, so the baseline you take today is the one you'll be glad you have. See DexaStrong →
Your scale gives one number. Your wearable estimates from heart rate and pace and can be off 10 to 20%. DexaFit measures directly: ±2% on body composition, and a mask that reads the oxygen you actually use for VO₂ Max. Same metrics your devices approximate, except these are real. Use the daily tools for daily signals. Use DexaFit for the truth.
Find your nearest DexaFit and book. The visit runs about 20 to 45 minutes, depending on what you schedule: an 8-minute DEXA scan, plus your VO₂ Max or RMR test. Your results are available the same day, with a real person walking you through personalized targets and a clear read on where you stand, ready to act on with your doctor, your trainer, or on your own.

Absolutely, that's the point. DexaFit isn't a plan, it's the ground truth you build one on.

Bring it to your doctor, your coach, or your own ambition. The data is yours.
