🏋️ Opening a gym or fitness studio

Why membership alone rarely works, and the churn number that decides whether you survive.

What the market is worth

US gyms & fitness clubs: $47.0B2026, up 1.3% — a 3.6% CAGR since 2021 (IBISWorld)
Growth character: Steady, not hota mature market; share is taken from competitors, rarely created
Where margin lives: Beyond membershippersonal training and small-group carry most studios' profit

How it actually grows

Pre-openSell before you build

Founding memberships sold during the fit-out fund equipment and prove demand before rent starts. If you can't sell 40 memberships to an empty room, the room won't fix that.

Watch out: Over-specifying equipment. Members leave over atmosphere and coaching, almost never over one missing machine.

Year 1Fill it, then measure churn

New gyms fill on novelty. What matters is who's still there in month seven — that number, not the sign-up count, predicts whether this works.

Watch out: Discounting to fill. A member acquired at half price rarely converts to full and anchors your pricing for everyone.

Years 2–3Add the profitable hours

Personal training and small-group are where studios actually earn. The same square footage produces several times the revenue per hour with a coach in it.

Watch out: Letting classes run under-filled out of habit. An empty 6am slot costs a coaching wage every week.

MatureRetention beats acquisition

At capacity, growth comes from keeping people longer and selling them more, not from more people. A one-point churn improvement is worth more than a marketing budget.

Watch out: Ignoring the quiet leavers. Most cancellations are decided weeks before they happen, and are visible in attendance data.

What each revenue stream is good for

Revenue stream	Pays	Scales
MembershipsThe base, and rarely the profit. Predictability is its real value.	Recurring, modest	Capped by space
Personal trainingUsually the largest profit line in a studio of any size.	Highest per hour	Capped by coaches
Small-group trainingThe best of both — near-PT margin, several people per coach hour.	High per hour	Good
Class packs / drop-insFills off-peak hours and feeds membership conversion.	Medium	Good
Nutrition / programmingSells to existing members with almost no delivery cost.	Good	Excellent
Retail & supplementsConvenience revenue. Real but never the plan.	Small	Medium

If you're starting this month

Sell founding memberships before the fit-out is finished. It funds the build and validates the location.
Track monthly churn from month one. Anything above 5% monthly needs fixing before you spend a dollar on ads.
Put a coach in front of every new member in week one. First-month contact is the single biggest retention lever.
Price personal training from the start — retrofitting it into a membership-only culture is much harder.
Watch attendance, not just billing. People stop showing up long before they stop paying, and that's your warning.

Before you trade on any of this

Fitness businesses carry real liability: waivers, insurance, equipment maintenance records, and staff certification all matter, and several states regulate how membership contracts and cancellations must work. Get the contract terms reviewed before you sell the first one.
