Apple will issue a New Year workout challenge to Apple Watch users through the built-in Activity app for the second year in a row. Users will receive a notification on December 28 informing them about the rules of the challenge. It is unclear if this will be a worldwide challenge at this point, Apple usually announces these challenges on Twitter.
To get the New Year Activity medal and iMessage stickers you will need to finish a workout in the Workout app every day and complete your activity rings for a full week in January.
