There’s a method to your madness when you hit the gym. From the first pull-up to the last curl, you’ve made it a habit to go all in or nothing. Monitoring your workout — well that’s a totally different story. Enter in the Echo H2 Sensor from Kenzen, the world’s first Bluetooth-enabled smart patch that continuously monitors hydration, lactic acid and calories – all from a single drop of sweat. Based on groundbreaking technology developed for aerospace and medical research, once connected, you get real-time vital statistics normally reserved for the sports lab. And not only does it accurately measure heart rate and activity, it captures your form in 3D and gives you the feedback you need to perform at your peak, increase endurance, avoid fatigue, and track recovery.
