Wearables have been around for some years now but since their inception into the health and fitness vernacular, wearables are being used extensively by gyms, personal trainers and their clients. People crave answers and love analysis, data - big and small. People want to understand their own progress, resting heart rates, improvements in BMI, flexibility, endurance, speed, strength and how they can do better. Wearables now capture a lot of real time data including personal best information. Tracking progress and performance is the normal in many gym environments but practitioners are only scratching the surface of how to embrace the power of this information. The industry of wearable technology is huge, estimated at over $27 Billion by 2022.
