Meet the KeenBrace: a smart wearable device that helps you maintain good form to avoid injuries. It also provides you with real-time voice coaching to keep you on the right track. KeenBrace counts your reps and monitors the balance and strength of engaged muscles.
Users will be able to see stride, speed, cadence, rep, muscle activation, and other info on their mobile device. The battery life lasts for 10 hours. You can wear this on your arm or thigh. Expected to ship in November.
