Exercise Lists (previously called class notes) are the written notes/lists that outline some classes on the website (not the apps).
This feature was implemented to help the members of Pilates Anytime who are teachers or student-teachers understand the class plan and see if the video contains a specific exercise they are looking for.
When you click on the exercise in the notes, it takes you directly to that spot in the video. These are printable, so you can take more detailed notes along the class outline.
Not all classes have notes, but you can search for those that do by going to the Search Page, and then clicking More and then selecting Has Exercise List.
