Know your engine.

Every test measures something your watch can only guess at. Start with the Baseline, or book one test on its own.

The Baseline — $349

Active Metabolic + Sweat Test, one visit. Both run best with normal fueling, so they go together. Includes a results report you’ll actually understand, plus your first sauna and cold plunge session at Mohawk (on-site). $442 if booked separately.

Resting Metabolic Rate (RMR) — $149

What your body burns doing nothing. You sit, relax, and breathe into a mask while we measure the oxygen you use and the CO2 you breathe out. You get your real daily calorie baseline and how much of it comes from fat vs. carbs at rest. Not racing? This is the test for you. It’s the most useful number you can have for fat loss, building muscle, or just eating right for how you actually live. You come in fasted, so RMR gets its own morning. Includes a sauna and cold plunge session at Mohawk when you’re done. Already booked the Baseline? Add it on a second visit for $99, with another sauna and cold plunge session.

Active Metabolic Test — $199

Your VO2 max, your real training zones based off your metabolism, and the point where your body shifts from burning mostly fat to mostly carbs. Done on the treadmill or bike, starting easy and building until you’re done.

Sweat Test — $199

How much you sweat and how much sodium you lose doing it. We weigh you, patch you, and send you out onto the LA River trail for a real run in real conditions. Then we build your hydration plan from what came out. Treadmill or bike are also testing options.
