Athletes are always looking for an edge, and wearable tech promises to give them just that. A slew of sports teams and elite athletes have been using smart garments to help them train harder, perform better and reduce injuries. I met with Jake Waxenberg, director of brand strategy for Athos, to talk about his company's smart compression clothing that uses electromyography (EMG) to track muscle activity and get the most out of a workout. As Waxenberg puts it: "Perfect practice makes perfect."
