Walk into most group fitness classes and you are a silhouette in the third row. The instructor is performing the workout at you, not teaching it to you. We decided early that Solstice would never run that way, and the mechanism is simple: no class, in any of our studios, ever has more than twelve people in it. Not on launch day, not during January resolution season, not when the waitlist is forty deep.
Twelve is not a marketing number. It is the largest group in which one instructor can actually see every body in the room. On a reformer, half an inch of pelvic tilt is the difference between a hamstring exercise and a lower-back complaint. At twelve, your instructor catches it on the second rep. At twenty-five, nobody catches it until it hurts.
The cap changes the social contract too. Your instructor knows your name by your second visit, knows about your cranky shoulder by your third, and programs around it by your fourth. Members tell us this is the thing they cannot get anywhere else — not the equipment, not the playlists, the being known. Our second-class booking rate for first-timers is 62%, roughly double the industry norm, and we are convinced the cap is most of the reason.
Yes, it costs us. A twenty-person class at the same price point would be a much prettier spreadsheet. Every time we model it, the numbers argue for loosening the cap and our churn data argues right back: members who report being corrected by name in their first month stay nearly twice as long. Retention is the whole economics of a membership studio. The cap is not in spite of the business model — it is the business model.
So when you book your first class and see only a few spots left, that is not scarcity theater. That is the twelve. We would rather you wait a day for a class where the instructor sees you than squeeze you into one where nobody does.
