Class schedule
A gym or studio's published timetable of group classes, each with a time, length, class type, instructor and room. Members and drop-ins book spots in a class from the schedule.
Class capacity
The most people one class session can hold, set by the room, equipment (such as bikes or reformers) or instructor ratio. When bookings reach capacity, the class is full and further sign-ups go to a waitlist.
Class pack
A pass that buys a set number of classes, such as five or ten, to use within an expiry period. Each booked or attended class uses one credit from the pack.
Class waitlist
The ordered queue of people waiting for a spot in a full class. When a booked person cancels, studios commonly auto-promote the first person on the waitlist into the class and notify them.
Late cancel
Cancelling a booked class or appointment inside the business's cancellation window, such as within twelve hours of start. Many businesses charge a fee or take a class credit for a late cancel because the spot is hard to refill.
