DEXA Body Scan
Know your
numbers.
The gold-standard scan for body composition. See your exact fat, lean muscle, visceral fat and bone density in about seven minutes. A measurement, not an estimate.
Between marathon training and lifting four to five times a week, I wanted real numbers, not guesses. Six minutes in the scanner and I had my baseline: 10.6% body fat.
A DEXA scan (Dual-Energy X-ray Absorptiometry) is the medical-grade body composition scan used to measure body fat percentage, lean muscle mass, visceral fat, and bone mineral density in one non-invasive, seven-minute session.
Unlike a fitness tracker, which only estimates, a DEXA scan in NYC uses low-dose X-ray technology to give you a precise, region-by-region breakdown of fat mass, muscle mass, and bone density. That includes visceral fat around your organs, a key marker of metabolic health that no scale can detect.

A DEXA scan uses medical-grade GE technology to break your body down into the numbers that actually matter: total fat, lean muscle, where fat sits, visceral fat around your organs, and bone density.
One of the easiest, most powerful tests you will ever take.
Two people at the same weight can have completely different bodies. The scale cannot tell fat from muscle, and it cannot see visceral fat, which is the fat most linked to long-term metabolic risk.
DEXA separates all of it, so your plan is built on what is really happening inside your body, and every retest shows real change.

1. Book and pay online. Reserve your scan in under a minute at the location nearest you.
2. Your scan, about 7 minutes. Lie comfortably on the scanner. No needles, no discomfort, no prep beyond skipping a heavy meal beforehand.
3. Walk through your numbers. Your care team reviews the report with you and shows you exactly what it means and what to do next.

98% accurate body fat percentage, lean muscle mass, and bone density readings. The gold-standard body composition scan, not a scale guess.
See exactly how much visceral fat sits around your organs versus subcutaneous fat, a key marker DEXA can detect that scales and calipers can't.
Identify left-right and regional muscle imbalances so your training plan can actually correct them instead of guessing.
Screen your bone density with a DEXA scan, an early health marker most routine checkups and standard physicals skip entirely.
View your results on an interactive dashboard so you can track body fat, muscle gain, and bone health changes over time with every retest.
A full DEXA body scan in NYC takes about 7 minutes, fully clothed, with minimal radiation, roughly the equivalent of eating four bananas.
Nicole scanned in January and came back in May. She lost 4.5% body fat.

We line you up so every scan is comparable to the last.

We sit down and read the numbers with you before you leave.
“Ten out of ten experience, super knowledgeable staff. I did the DEXA scan, RMR and VO2 max, then they sat me down and went through all of it, making sure I understood what my numbers meant and what to do next.”
“Bryan and the team have been consistently awesome to me and my friends. You get your raw scores, it is explained to you in person and on a handy app, and you leave with real recommendations on how to improve.”

“Matt was an incredible consultant. The optimization package finally gave me something concrete and efficient to work with. It has done a full 360 for my plans going forward.”
“Training for a race, I came in for the optimization package. Between the DEXA scan, RMR and VO2 testing, I have full clarity on where my health is and what I need to improve.”

“I am a big numbers girl, so seeing the detailed data from my DEXA scan and VO2 max was super helpful for my running goals. They guided and supported me through the whole process.”
“Super comprehensive results, all the detail on the app and a clear explanation in person. We loved it so much we bought a 6-pack so we can track our health journey.”

Five minutes of preparation is the difference between a reading you can trust and one you cannot.
Skip training on the day, before your appointment. A workout shifts fluid into muscle and moves your numbers.
Not dehydrated, not loaded up on water. Both distort body-composition readings.
No food for the two hours before your visit. Water is fine.
No underwire, zippers, buckles or heavy jewelry. Comfortable, plain clothing is ideal.
