Two headlines landed in the same week, and together they describe the fitness industry's next five years better than any forecast.
Planet Fitness cut its 2026 outlook. The budget-gym giant now expects adjusted net income to fall 3% this year, down from a previous 2% decline, with revenue growth trimmed to roughly 7% (from 9%) and sales expected to grow just about 1% — the slowest in years. Franchisee surveys peg Q2 net member additions at around 200,000, a modest bump on Q1 but well below the company's historical peak-season pace. Notably, Planet Fitness paused its planned national Black Card price increase pending a broader pricing review, and is testing pricing, member experience, and retention.
Meanwhile, private equity firm Permira lined up among a pack of bidders for Third Space, a 13-club luxury operator in London where members pay around £250 a month for five-star recovery spaces and bespoke training. The deal is valued near £700 million.
Why is the fitness market splitting into cheap and premium?
Because member-count growth has stalled at the bottom while spending power concentrates at the top. Planet Fitness built a decade of growth on adding bodies at $10–25 a month; that engine is now sputtering. At the same time, affluent consumers are treating wellness as a priority purchase, which is why private equity is willing to pay a premium for a £250/month operator. When you can't grow by adding members, the only way to grow is to earn more from the members you already have.
That single idea — ARPM (Average Revenue Per Member), the total revenue a gym generates divided by its active member count — is now the whole game. We flagged the leading edge of this when gym visits kept rising while visits-per-member fell: the industry is quietly running out of new bodies to sign.
How can a high-volume, low-price gym raise revenue per member without a backlash?
Lead with value, not price. Raising the base rate on an undifferentiated membership is what triggers churn. Instead, build optional tiers and ancillary services — recovery, small-group training, longevity add-ons — that willing members self-select into. Planet Fitness itself paused its Black Card increase and is testing experience upgrades and a $49.99 STUDIO tier rather than a blanket hike. The revenue-per-member gain comes from the members who want more, not from charging everyone more for the same thing.
This is the trap the middle keeps falling into: it raises the price on the same product and calls it a strategy. The members notice. The right sequence runs the other way. You earn the right to charge more by making "more" visibly worth it first — the exact discipline behind pricing a studio without racing to the bottom. Third Space is the extreme proof: £250 a month works because the value is overwhelming, not because the price is aggressive.
| Planet Fitness (HVLP) | Third Space (Premium) | |
|---|---|---|
| Monthly price | ~$15–25 | ~£250 |
| Historic growth lever | Member volume | Revenue per member |
| 2026 signal | Outlook cut, ~200K weak Q2 adds | ~£700M buyout interest |
| Where capital is going | Stalling | Flowing in |
What should operators in the middle actually do?
Build a value ladder above the entry tier, not a price hike on top of it. Keep the accessible on-ramp that fills the building, then give the members who want more a clear way to spend more: recovery suites, semi-private coaching, assessments, longevity services. That's the same instinct behind turning the floor into a ticketed revenue line — new dollars from existing members, no base-price backlash. The barbell economy isn't a threat to gyms in the middle. It's an instruction: pick an end, and give members a reason to climb toward it.
Planet Fitness spent fifteen years proving you could win by doing less for less. The next fifteen belong to the operators who figure out how to be worth more.
