Note: By default, every exercise in Superset's exercise library has three alternates. If you've added your own exercises inside of Superset, you'll need to add alternates to those exercises.
Open Superset's coach dashboard from your desktop.
Tap "Programs" and "Exercises".
Select an exercise you'd like to add alternates for, or search for it using the search bar.
Scroll to the bottom of the page and tap "Add alternate".
Select which alternates you'd like to add for that exercise.
