Keep your phone down and monitor the live workout from your wrist. Legend brings the active session, heart rate, set actions, rest controls, and sync state to Apple Watch.
How can I monitor heart rate while I work through a strength session?
How can I update sets, move between exercises, and manage rest from my Watch?
How can I keep Watch actions synchronized with the workout on my phone?
Apple Watch support is the wrist companion for the workout that is already active in Legend.

Use the Watch when you want the current session visible without picking up your phone:
The Watch view is intentionally companion-sized.
Apple Watch keeps the most common capture actions close when your hands are busy.

Handle small workout updates from your wrist instead of reopening the phone app:
The Watch controls are scoped to quick capture, not full workout editing.
Legend sends progressive-overload context for the active workout to Apple Watch so you can see the next useful target from your wrist.

The Watch context includes workout stats and exercise-level progression suggestions from the same engine used in phone capture:
That keeps overload guidance available when your phone is nearby but not in your hand.
