The promise on the timetable

We've gone from one gym to nine in a few years, and for a long time I told people it was a growth story. It wasn't. It was a story about a promise we were quietly failing to keep, and I didn't see it until it nearly cost us everything we'd built.

With one gym, my co-founder and I kept that promise with our phones and our memory. With nine gyms, the phones and the memory fell over, and we started breaking promises we didn't even know we were breaking.

People don't join Forge for the dumbbells; you can get dumbbells anywhere. They join for a specific instructor teaching a specific class at half six on a Tuesday, and they build their whole week around it.

When goodwill was the whole system

An instructor would get double-booked across two sites because two managers had grabbed her without talking to each other. A class would have no cover when someone was ill, so forty people turned up to a locked studio and a Post-it note. A new site would open with a timetable that was half guesswork.

What kept me up at night wasn't the logistics. It was what came after. In our world, a cancelled class isn't an inconvenience, it's the first domino in someone cancelling their membership. Somebody plans their Tuesday around a class, the class vanishes on them twice, and by the third time they've stopped planning their Tuesday around us at all.

A gym owner stands arms-crossed in a modern Forge Fitness facility, studying a large class timetable on the wall.

For ages I treated the timetable as an operations chore, the boring bit you delegate and forget. It isn't the boring bit. It's the product and it's the retention engine, and we were running the single most important thing in the company on goodwill and a WhatsApp group. Saying that out loud in a board meeting was genuinely embarrassing.

A launch that went wrong on purpose

We brought in Northpeak Crew to run one timetable across every site, with instructor certifications built in, so it physically can't schedule a spin class with someone who isn't signed off to teach spin. When someone calls in sick, instead of a manager panicking down the phone, Crew shows them instantly who else is qualified and free, often at a site twenty minutes up the road. Cover went from a forty-minute crisis to a two-minute job. Pulse sits on top of that and gives me fill rates, cover and cancellations across all nine sites on one screen, so I can spot a studio starting to drift weeks before it ever shows up in the membership numbers.

It didn't all go smoothly. We opened our Liverpool studio in the middle of the rollout and got cocky, assuming the system would sort the opening timetable on its own. We hadn't put the local instructor data in properly, and launch week was a mess: mislabelled classes, gaps, the chaotic opening we'd been trying to leave behind, except this time I couldn't blame the old way of doing things.

We owned it, fixed the data, and learned the hard way that the tool amplifies whatever you feed it; garbage in, faster garbage out.

What changed

The next studio we opened, in Sheffield, went live with the timetable full and fully staffed from day one. It had the strongest opening month of any site we've ever launched. The Liverpool mess directly bought us the Sheffield success; we'd never have got the data discipline right without that scare.

Cancelled classes are now a handful a month. I won't publish the before-figure, but I will say it was embarrassing enough that I stopped putting it in board decks. Fill rate is up, because we're building timetables around what members want and who's strong at teaching it, not around whoever happened to be free. The number I really watch is thirty-day churn after a let-down: how many people cancel within a month of a booked class falling through. We only started measuring it because of all this, so I can't give you a clean before-figure. What I can tell you is it's now low enough to have stopped being the thing I'm frightened of.

The night Sheffield opened, my co-founder and I stood at the back of a packed class, neither of us on our phones fixing something.

We didn't start a company to administer spreadsheets; we started it to build rooms full of people who walk out feeling brilliant.

The one thing you can't wing

My advice to anyone scaling a multi-site business: find the one operational thing your customers actually feel, and make it bulletproof before you scale, not after. For us it was the class timetable. For you it might be something else entirely, but you'll know it, because it's the thing that, when it breaks, customers take personally.

Don't kid yourself that heroics and memory will scale the way they did with one site. They won't, and the day they finally fail, your growth quietly goes into reverse, with nobody noticing until it shows up in the numbers months later. Find that thing now, while it's still fixable on your own terms.

Frequently asked questions
How did Forge Fitness reduce the time it takes to resolve a staffing crisis when an instructor calls in sick?
Before implementing Northpeak Crew, finding cover for a sick instructor at Forge Fitness took around 40 minutes of frantic phone calls. With Crew, the same task now takes two minutes, because the platform instantly surfaces every qualified and available instructor across all nine sites.
What measurable impact did Northpeak have on class cancellations and member churn at Forge Fitness?
Forge Fitness saw class cancellations fall from what co-founder Tariq Hussain described as a genuinely embarrassing level to just a handful. The metric Hussain tracks most closely—members who cancel their membership within 30 days of having a class cancelled—dropped to a level that, in his words, stopped being the thing that keeps him awake at night.
How does Forge Fitness use Northpeak Pulse to monitor performance across its nine gyms?
The Northpeak Pulse dashboard gives Tariq Hussain a single screen showing fill rates, cover statistics, and cancellations across all nine Forge Fitness sites. He says it lets him spot a studio starting to drift weeks before any problem would appear in membership numbers, giving the team time to act before members are lost.
Which Northpeak products did Forge Fitness use, and what specific scheduling problem did each solve?
Forge Fitness used Northpeak Crew and Northpeak Pulse. Crew provided one master timetable across all nine sites and enforced instructor certifications—physically preventing, for example, a spin class from being assigned to an instructor not qualified to teach it—while Pulse gave leadership a single-screen view of operational health across every location.
What lesson did Forge Fitness learn from the troubled launch of its Liverpool studio during the Northpeak rollout?
When Forge Fitness opened its Liverpool studio mid-rollout, the team had not entered local instructor data correctly, resulting in mislabelled classes and schedule gaps during launch week. Hussain credits that painful experience with building the data discipline that allowed the next opening, in Sheffield, to launch with a full and fully staffed timetable from day one—the strongest opening month of any Forge Fitness site to date.
