Weighted exercises now log their configured weight to your session (they were logging as bodyweight), so volume and estimated 1-rep-max reflect the load you lifted. Also improves automatic rep counting for biceps curls, ring rows and pike push-ups.
Smarter rep counting: per-exercise and learned from real training data, tuned live on the watch. Sessions now sync even if your phone is out of range during a workout - the watch queues them and uploads when it reconnects. A 3-2-1 get-into-position countdown before every set, and a clearer rest screen showing what's next.
