About the test
We measure exactly how much fluid and sodium you lose per hour of training, using a wearable biosensor that reads your sweat in real time. No estimates, no generic hydration advice. You get your personal sweat rate, your sodium concentration, and a precise fueling protocol built on your biology. Stop guessing what to drink. Know it.
