Running a gym

What breaks at every stage of gym growth

Under 80 members, 80 to 150, and 150-plus. Each stage strains something different. Here's what to watch for.

Every gym that grows hits the same walls in roughly the same order. None of them are a sign you're doing it wrong. They're a sign the way you ran the gym at the last stage has done its job.

This is a three-part series. Each part covers one stage, what tends to break, and what helps.

Under 80 members: building the framework

At this size the head coach usually knows every member by name and can see who's improving. The thing that's often missing is a teaching framework: a curriculum, a grading standard, and session plans that another coach could pick up.

It feels optional while the room is small. It becomes essential the moment you hire a second coach or open a second class time.

  • Write down what each belt is expected to know.
  • Plan sessions in blocks, so a week of classes builds on itself.
  • Record grading as it happens, not from memory at the end of term.
A system you start at 40 members is one you don't have to rebuild at 140.

80 to 150 members: the cracks show

This is where most owners feel it. Recognition starts slipping: someone has been ready for a stripe for months and nobody noticed. Software costs creep up as you add a tool for each new job. Coaches carry admin home with them.

The common answer is an admin hire. It helps, but it often moves the problem rather than solving it, because the information is still spread across spreadsheets, inboxes and group chats.

  • Put every belt, stripe and attendance record in one place.
  • Make recognition a routine, not something a coach has to remember.
  • Count how many tools you're paying for, and what each one actually does.

150+ members: quiet drift

At this size the gym runs. The risk is less visible: members who drift from three sessions a week to one, then stop, without anyone being told. Trials that don't get a follow-up. Memberships that lapse and aren't renewed.

None of it shows up as a single bad month. It shows up as revenue that doesn't grow the way the timetable says it should.

  • Flag members whose attendance is dropping, early enough to check in.
  • Automate trial follow-ups and membership renewals.
  • Keep coaches close to members, so the check-in comes from a person they know.

Where Pilot fits

Pilot was built by gym owners who hit each of these stages themselves. It carries the admin at every size, so the coaching stays front and centre.

You coach. Pilot handles the rest.
