For the second year in a row, Apple will issue a New Year workout challenge to Apple Watch wearers through the built-in Activity app and an upcoming wrist notification.

The challenge will appear in the Activity app on your paired iPhone and Apple Watch. Users will receive a notification on December 28 informing them about the rules of the challenge.

You’ll need to finish a workout in the Workout app every day and complete your activity rings for a full week in January to earn exclusive iMessage stickers and a medal in the Activity app.

Apple usually announces these challenges on Twitter and with a press release so stay tuned as we’ll bring you more details as soon as 2018’s New Year challenge goes official.
