Athos is applying smart technology to fitness in a novel way. They aren’t just creating fitness trackers; their apparel allows you to track muscle performance in real-time.

Athos’ smart apparel uses built-in sensors to measure muscle performance including muscle effort, heart rate, and breathing rate. It sends that data to the “Core,” a pebble-size device that’s the brain of the system. The Core then sends that information to your smartphone via Bluetooth. All you need is an app on your smartphone.

The app will relay information and give you tips on how to get better and faster results. The app will also let you know if the way you are working out is putting you in danger of being injured. In addition, the app will track rep counts and tell you what muscle groups are straining the most. In other words Athos’ apparel will manage and optimize your workout.

Athos’ apparel starts at $199.
