MustDuo

Warm up the right way: every workout now starts with a short warm-up built from your first lifts, with lighter sets before the heavy ones. Train with a friend in Duo mode: share a code, take turns, and see what you lifted together. Share a workout: a friend scans your code and gets the same exercises in the same order, with their own weights. Use Siri with MustDuo. Say "Start my workout in MustDuo", "How's my week in MustDuo?" or "Ask Naya in MustDuo". Your week on the Lock Screen, and today's workout one tap away in Control Center or on the Action button. A new This week card on Home shows what's done, what's left and your streak. Fixes and polish.
