Most of today's wearable fitness tech does a great job of setting goals, organizing workouts, and tracking progress, but most of it actually doesn't help you out when it comes to the nitty gritty of the actual exercises themselves. Harnessing well-established EMG technology, Athos uses sensors to track your muscle activity, effectively measuring how hard each muscle group is working and letting you know if you're in balance.
After you first put on an Athos garment, the app analyzes your muscles and calibrates as you walk around. When everything is set up, the app will communicate realtime data on which muscle groups are straining. Flex your guns, and you see the biceps area light up. Do a push up and you'll see the chest area glow.
Since you obviously can't be checking your phone during a squat, the app will record your workout and you can play it back after you've unloaded. Like a personal trainer, Athos will count your reps and measure your effort against past efforts, scoring your workouts and helping you improve.
