Our Science


What Makes Us Different

We offer each athlete a custom, individualized training plan that automatically “recalculates” when life gets in the way. Our technology uses proven zone training and personalized biometrics to drive our patented, machine learning-based algorithm that creates an effective, personalized, science-backed solution for anyone looking to improve their training regimen.

We’ve also developed a sensor to measure blood lactate noninvasively. Exercise physiologists describe this analyte as the “Gold Standard” for athletic training. It’s important enough that elite competitors routinely draw blood to measure their lactate levels. Our wristband sensor measures blood lactate in real-time during exercise—eliminating the need for needles and allowing even beginners to train as efficiently and effectively as the world’s best athletes.

Working in concert, these combined technologies help make every minute count with a smarter approach to training.
