What we test in Gilbert
One visit.
Three clear answers.
Each test returns a single clinical-grade insight. Take one, or stack two or three in the same Gilbert visit for the fullest read on your physiology. Choose your tests in the scheduler and you are set.
DEXA Body Composition Scan
The gold standard for body composition. A single open-air scan charts fat mass, lean tissue, and bone density region by region at ±2% clinical accuracy, so you learn what your body is built from rather than what it weighs.
VO₂ Max Test
The ceiling on what you can do and the floor on how long you live. Walk or run on a treadmill while we measure your true aerobic capacity, then map out how to raise it. No watch estimate comes close.
Resting Metabolic Rate (RMR) Test
Off-the-shelf calculators can miss your real metabolism by as much as ±20%. Breathe into a mask for 15 minutes and leave with the exact daily calorie baseline your body runs on, so your nutrition works with your biology instead of against it.
Stack Your Tests
Pair any two tests, or take all three in a single Gilbert visit, for the most complete picture of your body. Add what you want when you choose your time in the scheduler.

Quick answers
Gilbert questions.
DexaFit Gilbert sits at 5656 S. Power Road, Suite 124, Gilbert, AZ 85295, near the Power Road corridor and the SanTan area. It is a short drive for most of the southeast East Valley. You can book DEXA body composition, VO₂ Max, and RMR testing online and pick a time that works for you.
Yes. A DEXA scan uses a very low dose of X-ray radiation, well under a standard chest X-ray and on par with a few hours of the background radiation you absorb in ordinary daily life. The technology has anchored hospital and research work for decades and is regarded as safe for most healthy adults.
Plan on about an hour if you stack all three. The DEXA scan itself runs roughly 8 minutes, VO₂ Max about 15, and RMR about 15 minutes of quiet breathing. Single tests are quicker. The rest of the time covers check-in and a walk-through of your numbers before you leave.
Start with the DEXA scan. On GLP-1 therapy the scale drops, but it cannot tell you what kind of weight left. Roughly 1 in 3 pounds lost on GLP-1 is lean mass, and a DEXA shows whether that describes you. Add RMR and you learn how the loss is reshaping your metabolism.
Yes. DexaFit reports use the same clinical technology and terminology your physician already reads. Gilbert clients regularly share their numbers with a primary care doctor, endocrinologist, sports medicine physician, or dietitian, and the data drops straight into that conversation.
Most clients return every 3 to 6 months. Your first visit sets a baseline. Each repeat session shows whether your training, nutrition, or medication is moving the numbers you care about, measured down to the tissue level rather than guessed at on a bathroom scale.
