If you can track the percentage of members that participate in your classes, vs the amount that actually walk in the door you can build a case.
I’ll equate this to a college. If the football team generates the most revenue or has the most fans, they should get the most money right? I read somewhere that the national average is around 13-15% penetration for group exercise. (I’ve asked a question as well to find out relevant information on this too). I guess you could argue then that the department should receive that percentage?
we’ve been tracking data for years to build a case. how many people are in each class (the instructors report this), and how many people are in the building during that class- we check through our membership software. At some times, we have up to 50-80% of the members in the facility in one of our classes.. (pretty good case for more money huh?)
