This is an example of a filtering techniqe I used for a client when building an extensive strength template. There was a database with over 1000 exercises split up into different categories, this is just a sample of the function, in the actual buid there were four slicers to sub-categorize the exercises.

Also, a lot of the time coaches will have a rough idea of the exercise they are going to program but maybe just want a little variation or a list to consider their options.
