Body Composition

Your bathroom scale sees a pound. A DEXA scan sees what it is made of.

A DEXA scan sends a low-dose X-ray the length of your body and pulls fat, lean muscle, and bone density into separate readings, mapped limb by limb and trunk by trunk. This is the same measurement hospitals and research labs treat as the reference standard, and the scan itself takes under 8 minutes. You leave knowing exactly where your body stands and which arm, leg, or region deserves your attention first.

VO₂ Max Test · 45 min

VO₂ Max Test

One number tells you more about your future than almost any other.

VO₂ Max measures how efficiently your body takes in oxygen and converts it to effort as the workload rises. Whether you log miles on the Brushy Creek Trail or simply want more energy for a full day, it reflects far more than fitness. As a longevity marker it carries more weight than smoking, blood pressure, or cholesterol. You breathe through a mask, work through a graded treadmill test, and we capture your true ceiling. From there, the number becomes a plan to lift it.

The least-fit group faced roughly 5 times the death rate of the fittest, across a study of 122,007 people (Mandsager et al., JAMA 2018).

RMR Test · 30 min

Resting Metabolic Rate

Your diet is built on a calorie target that was never actually measured.

An RMR test reveals how many calories your body burns doing nothing at all, the true baseline every meal plan should be built on. The generic calculators most people rely on can miss the real figure by 20 to 30%, and that error is why fat loss stalls and carefully counted macros go nowhere. Fifteen quiet minutes breathing into a mask hands you a number drawn from your own metabolism rather than an average of someone else's.

±20%
The typical gap between a calculated metabolic rate and a measured one. That margin quietly sinks most nutrition plans long before the scale would ever hint at why.

DexaStrong Scan · Bone Density

Bone Density

Bones lose strength quietly. A DexaStrong scan catches it early.

DexaStrong is a site-specific bone mineral density scan built on the same clinical-grade DEXA technology, reading your spine and hip as T-scores and Z-scores. It flags low bone mass and rising fracture risk years before a break, so you can act while there is still time to protect your skeleton.

Biomarker lab testing panels at DexaFit Round Rock
Biomarker Panels · Bloodwork

Lab Testing

Body composition is one layer. Your bloodwork is the next.

Biomarker lab testing measures what a scan cannot see: the markers in your blood tied to metabolism, inflammation, hormones, and long-term wellness. Choose a targeted panel, add it to your visit, and read your inside story alongside your body composition. Your results are yours to keep and to share with your own healthcare provider.

Numbers are the start. A plan is what changes them.

Concierge nutrition matching pairs your DEXA, VO₂ Max, RMR, and biomarker results with a nutrition professional suited to your goals. Instead of a generic template, your plan is built around your own measured numbers, so the work you put in actually moves them.
