# Add an activity to one day of the client's plan

> Swimming and rowing require the cardio composite gate. Adds ONE activity to one day of the client's own programme — the "Add Activity" sheet.

This is the minimal-payload replacement for sending the whole `schedule.weeks[]` blob to `PUT .../plans/{planId}/calendar-schedule`: the target day is addressed by the URL and only the new activity travels in the body, so the client never echoes back items it is not touching — and can never drop one by omitting it.

Appended LAST on that day. An unauthored weekday is created on demand. A REST day is refused (`WORKOUTPLAN_ITEM_ADD_REST_DAY`).

Requires the workout_client_plans:write scope. This operation maps to /app/v1/workout/plans/client/template/:templateId/weeks/:weekNumber/days/:weekday/activities and retains its Workout V2 permission, feature-flag, and resource-scope checks.

The clientId path parameter identifies the client represented by the request context.
