Everything you can do to a routine lives in its menu on the Workouts tab. Open the menu on a routine card to see the options.
Edit
Opens the routine editor where you can add or remove exercises, change sets, targets, and rep ranges, reorder exercises, and edit the description.
Rename
Changes just the routine's name.
Duplicate
Creates a copy of the routine (named "… (Copy)"). Useful for building the next training block from the current one, or an easier variant of the same day.
Delete
Permanently deletes the routine. Your completed workouts are untouched — deleting a routine never removes anything from your history.
Reorder your routine list
Choose Reorder Routines to drag your routines into the order you like on the Workouts tab — for example, matching your weekly split.
