Add a selection screen with all exercises available within NexGym and allow users to exclude for use in the system generated 15 Day workout. Have pre-set exclusions for common situations (e.g., pregnancy, knee injury) that users can further modify, see necessary.
These could be grouped by focus area (e.g., upper body, core) or exercise type (e.g., Squats: basic squats, dumbbell squats, iso squats (with a max duration modifier), sumo squats, goblet squats).
