Stop guessing.
Start knowing
your metabolism.

You'll wear a clinical-grade mask that analyzes your breath while you're either resting (RMR) or during light to moderate exercise (VO2 Max). The test takes less than 10 minutes, requires no blood draw, and is completely non-invasive. Results are available immediately after the session.

Pricing depends on which assessment is right for you. When our team calls you after you apply, they'll walk you through the options and costs based on your goals. There's no commitment required to apply.

For the RMR test, you'll be asked to fast for at least 4 hours beforehand and avoid caffeine and intense exercise that day. For the VO2 Max test, wear comfortable athletic clothing and avoid heavy meals 2–3 hours before. Our team will send you full prep instructions once your appointment is confirmed.

Your RMR is the exact number of calories your body burns at rest just to keep you alive — powering your heart, lungs, brain, and cells. Most people guess this number using generic online formulas that can be off by hundreds of calories. Knowing your true RMR means your nutrition plan is built on real data, not estimates — which is why so many diets fail.

VO2 Max is the maximum amount of oxygen your body can use during intense exercise — it's the gold standard measure of cardiorespiratory fitness. A higher VO2 Max is one of the strongest predictors of longevity and overall health. The test also reveals your personal heart rate training zones, so you know exactly what intensity to work at to burn fat, build endurance, or peak for performance.
