If you wanted to simplify, CES 2019 could be neatly divided into self-driving cars, giant TVs and health tech. A lot of what we've seen of the latter either tracks your movement or is hardware ingrained into workouts. Spryng is a little different, aimed at speeding up your recovery, reducing muscle soreness by stimulating blood circulation. While looking like an unassuming pair of chunky shinguards, these tech-laced wraps expand and contract around your calves, improving blood flow and feeling very nice in the process. The startup showcased the portable muscle recovery tool at CES, and it's backed up by several scientific papers that elaborate on the medical applications of active compression.
