Meet the Lumo Run: a smart wearable system that helps you become a better runner. It comes with a lab-grade 9-axis sensor and algorithms to capture and analyze your running biomechanics through your core. You also get audio coaching through your headphones to get on the right track. You will be able to monitor cadence, bounce, pelvic rotation, stride length, and other data on your smartphone.
Lumo Run does not require you to deal with wires and handheld devices to monitor your workout. The sensor is waterproof. You can pre-order yours here.
