If you’re into fitness, people would suggest getting a wearable. What they mean by this is usually some sort of wristband that counts your steps. That’s not hardcore enough for the serious fitness fan. For them, there’s the Athos, the wearable for your actual gym clothes.

This gadget attaches directly to specialized clothing to monitor a variety of physical outputs. This is looking at more than just how many steps you’ve taken and what your heartbeat is. This looks at a totality of your movement and combines that information to let you know how your workout is going and where you can push yourself further.

It records your form, muscle exertion and utilization, and balance as well as your heartbeat and respiration. It takes this data and lets you read it through the app. The Athos does need its specialized clothing to work properly, otherwise, you can’t attach it but for people who are ultra-serious about time in the gym, this particular wearable might be able to kick their workout into high gear. The Athos is $199 but requires the purchase of at least one garment in addition.
