Zone 2 has been rebuilt from the ground up, and it now runs your workout with you. LIVE ZONE WORKOUTS ON APPLE WATCH Pick an activity, a target zone and how many minutes you want in it. The watch shows your heart rate on a five-zone ladder and a countdown that only moves while you are in the zone. Drift high and it says EASE UP, drop low and it says PUSH, with distinct taps on the wrist so you never have to look. Rate the effort at the end and see what the workout added to your week. FOLLOW ALONG ON IPHONE A running workout shows up as a Live Activity on the Lock Screen and in the Dynamic Island, with pause and resume, plus a full live screen in the app. Everything travels directly between your devices. A NEW HOME Your week is now a set of rings, one per goal zone, with the minutes left to close each one, a week-over-week comparison at the same point in the week, and a streak that counts the weeks you closed Zone 2. ZONE TRENDS Every zone has its own page with a ten-week trend against your goal line, your average and best week, and the workouts that contributed. WORKOUTS TAB Build workouts on iPhone and they appear as quick picks on the watch. Logged workouts have a new detail view with time in each zone, a heart-rate graph and what the session added to your streak. AI COACH (PREMIUM) Ask how to close the minutes you have left, whether to raise a goal, or where a harder session fits. The coach works from your own data, proposes goals you apply with one tap, and runs on Apple Intelligence with Private Cloud Compute. ALSO Weekly goals for any zone, Health app zones or age-based ranges, a Monday or Sunday week start, and Live Activity pause and resume. Custom workouts no longer go into the Workouts app on the watch; they run inside Zone 2 instead.

Fixes a bug in the calendar that would cause some elements to not be tappable.
