The five gym KPIs to check every week are trial sales, trial conversion rate, monthly attrition, member lifetime value, and profit. Review them in a 30-minute health check every Monday. Each one points to a different fix: marketing, sales, product, or pricing. Together they replace gut feel with facts.
This is the dashboard Jenz Robinson installs with gym owners inside Gym Owner Network. Before they tracked properly, almost every owner we surveyed said the same thing: they were making decisions on emotion, not facts. The video walkthrough is below.

The 5 Numbers Every Gym Owner Should Check Weekly
Why running a gym on gut feel keeps you stuck
Picture Sunday night. You're lying in bed and your brain starts racing. How many trials did we do? Will we hit revenue? Why did that member cancel? Is the marketing even working?
That's what running a gym without numbers feels like. It's like flying a plane in a storm with no instruments. You might feel level. You could be upside down.
The symptoms are familiar. Cash flow surprises, where one month you're celebrating and the next you're scrambling for rent. No idea which marketing works. No way to tell if your team is underperforming or just overwhelmed.
One owner told us: "I used to bury my head in the sand because I was scared of what the numbers might tell me." Gut feel is built on survival. Data is how you thrive.
What are the 5 gym KPIs to track weekly?
Forget the spreadsheet with 47 columns. Think of these five like vital signs in a hospital. You don't need twenty readings. You need the right five to tell you if the patient is healthy.
| KPI | What it measures | Benchmark | If it's off |
|---|---|---|---|
| Trial sales | People starting your front-end offer | Steady week to week | Marketing problem |
| Conversion % | Trials that become members | Around 65% | Sales or product problem |
| Attrition | Members lost each month | Under 3% is winning | Product problem above 5% |
| Lifetime value | What leavers were worth, and when they left | 18+ months in strong gyms | Onboarding or retention gap |
| Profit | What's left after every cost | Growing, not just turnover | Pricing or model problem |
1. Trial sales
This is your lifeblood: how many people walk through your door to try your service. If this drops, you know you have a marketing problem before it hits your bank account.
2. Conversion percentage
What share of trials become paying members? Around 65% is a common industry average. If you're below it, look at your sales process and your product.
3. Attrition rate
How many members you lose each month. Above 5% means a serious product issue. Below 3% means you're winning. We go deeper in our guide to gym attrition rate.
4. Lifetime value, in reverse
Most owners guess what a member is worth over their lifetime. Work backwards instead. Look at everyone who left in the last six months and find the drop-off point. If they all leave around month four, that's where your product breaks.
5. Profit
Turnover is vanity. Profit is where freedom is built. Know your actual profit every month, not just what came in.
How do you run a weekly gym health check?
Every Monday, spend 30 minutes with your five numbers from the previous week. Treat them as a diagnostic, not a report card. Find the one number that's off, name the area it points to, and decide what you'll do about it this week. Then look at the trajectory if nothing changes.
The diagnosis is straightforward:
- Trials down? Marketing.
- Conversion down? Sales, product, or team.
- Attrition up? What's happening on and off the floor.
- Profit thin? Cheap memberships, or selling the wrong things.
- Team not executing? That's a leadership challenge.
What does your gym's trajectory look like?
Trajectory is the question most owners skip: if nothing changes, where will this number be in 12 months? It turns a weekly figure into a forecast, and it shows you which small problem is quietly becoming a big one.
At 8% monthly attrition, you replace almost your whole membership every year. That's a revolving door, not a business. A conversion rate sliding from 65% to 60% doesn't cost much today. It trains your team to expect failure.
The owners who track this way tell us the same things. They're no longer emotional when a member leaves, because they can see why in the data. Their team respects them more, because decisions are based on facts.
