How to reduce no-shows in group classes

Measure it before you fix it

No-show rate is booked places that were not attended, divided by booked places, over a period. Track it per time slot, not as one number for the gym: the 06:00 and the 19:00 are different businesses with different problems, and averaging them hides both.

There is no rate that fits everyone, and Rummo has no market data to invent one. What you compare is inside your own space. A time slot with far more no-shows than the others is almost always one of four causes.

The four structural causes

1. Cancelling is harder than not showing up

If cancelling takes more than two taps, or requires messaging a human, some people will simply not do it. The fix is not a policy. It is putting cancel in the same place as book, at the same size.

2. The cancellation window is too long, or too short

A twelve-hour window means the place is released at 19:00 for a 07:00 class, when nobody is looking. A one-hour window means the place is released too late to be filled. For morning classes, close the window the previous evening and promote the waitlist immediately. That puts the place in front of people while they are still awake.

3. Nothing happens when you do not show up

This is the uncomfortable one. If a no-show costs nothing, it costs nothing. The lightest version that works: an unused place on a limited plan counts as used, and the member can see that it did. No fines, no emails, no drama. The rule is visible before the booking, and it applies itself.

4. People book a week of classes on Sunday

Booking seven days ahead feels like commitment on Sunday and feels like an obligation on Thursday. Some spaces cap how far ahead a member can book. It cuts the number of bookings, and the ones that remain are used more often.

Every measure in this guide does the same thing: it makes the place available to somebody else sooner.

What to do this week

1. 1.Pull the no-show rate per class time for the last eight weeks.
2. 2.Pick the worst slot. Only one.
3. 3.Set the cancellation window so the place is released while people are awake.
4. 4.Make sure the waitlist promotes automatically and tells the person.
5. 5.Leave it four weeks, then look again before changing anything else.

Four weeks is not arbitrary: with a class of twelve twice a week, anything shorter is too few data points to tell a change from a quiet fortnight.

What not to do

• Charging a fee before you have fixed the cancellation flow. You will be charging people for your own friction.
• Reminder messages as the first intervention. They help at the margin, and they are the easiest thing to add. Without the window and the waitlist fixed, they change little.
• Changing four things at once. You will never know which one worked.
