Class type is the name of the class rather than class format. That means there are too many choices. Classes should be tagged with format type, for example, "Strength", "Core Strength", and "Bootcamp" can all be "Strength" for a filtered search. They'd still have unique names, but easier to search. Often times, "Simply Yoga" "Pilates" "All Levels Yoga" would be tagged with format "Mind and Body." Some class types would have multiple tags/format types. For example, "Kickboxing" might be tagged "Cardio" and "Strength"
