Space Calculations for a Group Fitness Room

Here is a bit of fitness info that might be of interest. This is from Michael Scott Scudder on group fitness classes.
First, establish your Maximum Room Capacity:
Square Footage of your exercise room less 100 Divide that number by 35
This number is your maximum number of participants per class

Example: 1500 square foot exercise room (1500 - 100 = 1400/35  = 40 - your  MRC)

Next, recognize that if you do not have at least 30% of your MRC in attendance in a class;
you should either change instructors, change the class or cancel it outright! (In the above example, a "breakeven class" is no less than 12 attendees.)

Next, count how many classes you have per week...keep a sign-in sheet of each class (you need it for insurance liability anyway).
Now, after 4 weeks of accumulated sign-in sheets, count how many attendees, divide by the total number of classes and you arrive at your Average Attendance Per Class (AAPC).
Any class that has less than the AAPC in attendance over that time period should be considered for change of instructor, class venue or cancellation.
