This wearable helps endurance athletes understand their bodies. Humon Hex is worn around any muscle. Sensors are able to detect oxygen levels in the muscles in real time. This is the most accurate indicator of fatigue that you can get. Most other fitness trackers only are able to measure heart rate.

Comparatively, this is a much less reliable way to understand workouts. By measuring oxygen, Hex lets elite athletes know in real time, exactly how far they can push themselves before reaching physical limits. This is an invaluable training tool for athletes looking to be the best. Is Humon Hex the future of high performance athletics training?
