What you can book
Three tests.
One north Phoenix visit.
Each test answers a different question about your body with clinical-grade precision. Book one, or stack two or three the same morning for the fullest read.
DEXA Body Composition Scan
The gold standard for body composition. A single open-air scan reads fat mass, lean tissue, and bone density region by region at ±2% clinical accuracy, so the number on your scale stops being the whole story.
VO₂ Max Test
The most reliable single predictor of all-cause mortality. Walk or run while we measure your true aerobic ceiling, then map the work that raises it. Your watch estimates this number. Here you measure it.
Resting Metabolic Rate (RMR) Test
Formula-based calculators can be off by 20 to 30%. Breathe into a mask at rest for 15 minutes and leave with the exact number of calories your body burns doing nothing, so your nutrition runs on your biology rather than a guess.
Stack Your Tests in One Visit
DEXA, VO₂ Max, and RMR each measure a different layer of your physiology. Booking two or three in a single north Phoenix appointment gives you the complete picture and one trip instead of three.

North Phoenix offers three tests: the DEXA body composition scan, the VO₂ Max test, and the RMR metabolic test. You can book one on its own or stack two or three in a single visit.
Yes. A DEXA scan uses a very low dose of X-ray radiation, far below a standard chest X-ray and close to a few hours of the background radiation you take in during everyday life. The technology has been used across hospitals and research for decades and is regarded as safe for most healthy adults.
The DEXA scan takes about 8 minutes. VO₂ Max runs about 15 minutes. RMR is about 15 minutes of quiet breathing. Booking all three at one north Phoenix visit usually has you in and out in under an hour, including check-in and a results walk-through.
On GLP-1 therapy, start with the DEXA scan. It shows whether the weight coming off is fat or muscle, which a bathroom scale cannot. Roughly 1 in 3 pounds lost on GLP-1 is lean mass, and a DEXA tells you whether you are in that group. Add RMR to see how your metabolism is responding.
Yes, and we recommend it. DexaFit reports use the same clinical-grade measurement and terminology your physician already works with. Many clients hand their results to a GP, endocrinologist, sports medicine doctor, or dietitian, and the data slots straight into that conversation.
