Workouts are ordered lists of exercises performed together. Organizing exercises into a Workout allows you to have groups of exercises together in one area for easy entry of results. Using Workouts also allows you to group exercise records in the History pages so you can view results only for a particular Workout.
Create / Edit Workouts shows you how to create a new Workout, or modify an existing one.
