Stop estimating your body.Start measuring it.
DexaFit Phoenix brings clinical-grade testing to the East Valley across three nearby locations in Tempe, Gilbert, and North Phoenix. DEXA body composition, VO₂ Max, and RMR, run on the same instruments trusted in research hospitals and peer-reviewed studies.
The baseline that sits under every health decision you make.
A digit on the scale. A streak on your watch. A marker on a lab report. None of them tells you what your body is built from, what it can withstand, or what fuels it through the day.
DexaFit was founded in Chicago in 2011 on a single idea: your body should be measured, not estimated. That standard now reaches across four continents and over a decade of real-world data. Here in the Phoenix metro, three locally owned partner locations carry it into the East Valley.
We sell no diet, no supplement, no training plan. We give you the numbers that show whether yours are working. Measure first. Decide after.
Three tests. One clear answer.
Each closes a question your scale, your mirror, and your wearable leave wide open.
DEXA Scan
See what you are made of.
A quick, open-air scan maps fat, lean muscle, and bone density region by region, plus the visceral fat wrapped around your organs. It reads body fat to within roughly ±2%, where a smart scale can wander 8 to 15% off.
VO₂ Max Test
The ceiling on what you can do.
A guided effort test measures how well your body takes in and uses oxygen. Across 122,007 people, the least fit carried a fivefold mortality gap against the most fit, a stronger signal than smoking, blood pressure, or cholesterol. Your watch guesses this number. We measure it.Mandsager et al., JAMA 2018; N = 122,007.
RMR Metabolism Test
Know what you burn at rest.
A few minutes of quiet breathing reveals your resting metabolism, read straight from breath analysis rather than guessed from a formula. App and calculator estimates can miss by 20 to 30%. Your meals get built around your actual figure.
Clinical-grade, read against the benchmark that matters.
A number says little without the right comparison next to it. We read every result against age- and sex-matched reference ranges, then translate it into plain language you can act on. You leave knowing where you stand and what comes next.
DexaFit works alongside your physician, your coach, and your wearables, never in their place. We are the baseline the rest of your plan gets measured against.
Come back in a few months and the numbers report back without flattery: what moved, what held, and whether the plan earned its place.
