Apple presents these wearables as pieces of everyday tech to be incorporated into normal workouts. Most of the devices shown in the ad — including the Zepp golf sensor and the Adidas miCoach smart ball — are available already from Apples own store. Apple, which is reportedly starting to move more of its TV advertising efforts in-house, released Strength only a few days after it demonstrated HealthKit, a collection of apps that will come bundled with iOS 8 that allow users to keep track of their fitness data. HealthKit apps can share your personal information between each other, meaning users of the apps and devices in Apples latest ad will be able to build up a detailed picture of their overall fitness.
