Last year, Adidas made a commitment to help young students stay fit and healthy. This idea was born after the sportswear giant teamed up with Interactive Health Technologies, a firm that provides a connected fitness-assessment platform to schools in the US. Together, they created The Spirt Challenge, which encourages students from kindergarten through high school to be active. In exchange for doing that, they get rewarded prizes such as apparel, equipment and scholarships. And now Adidas is taking its efforts one step further, introducing a wrist-worn wearable designed for physical education classrooms.
