All of the exercise categories are hidden so that they don't print: it takes up valuable real estate on the printed template!

To unhide them, we use a feature called "grouping".  Above the top columns you will see little + signs, you can click those and it will display the category and option dropdowns:



To close them, just select the "-" sign and it will rehide them!  Also, you can bulk open and close them using the 1 and 2 to the far left of the hidden groups.
