The Big Box Gym Model Is Breaking. Here’s What Comes Next
By Burn Boot CampMay 22, 2026A century ago, working out was largely off-limits to women.
Today, women make up roughly 75% of boutique fitness memberships.
The category got rebuilt once. It is being rebuilt again.
And most people in the industry are watching the wrong signals.
The headlines have been about strength training, wearables, recovery rooms, cold plunges, the latest celebrity-backed concept opening in Miami. Real, but not the story. The actual story is structural, and it is happening underneath the brand-level noise: the model that built the modern fitness industry is quietly breaking.
The question worth asking is not whether fitness is a category with a future. The question is which kind of fitness brand is built for the next ten years, and which one is running out of road.
The answer is starting to come into focus.
The Shift From Activity to Training
For most of the modern fitness industry's history, the product has been access. A membership bought you the right to use a building. What you did inside was your problem. Big-box gyms scaled this brilliantly: the more members who paid and stayed home, the better the unit economics looked.
That model is breaking. Not because members stopped paying, but because they stopped accepting access as the deliverable. They want a plan, a program, and a result. Devin Klein, co-founder of Burn Boot Camp, has been calling this shift for years. His framing is simple: the entire industry, from the lowest-priced national chains to the highest-touch personal trainers, is converging on the same thing.
"People will expect to get results out of their regimen, out of their membership. It will move from activity and exercise to training. Activity and exercise are unplanned. Training is planned."
-DEVAN KLINE
The implication is structural. A brand whose product is a building is exposed to commodity pricing pressure. A brand whose product is a periodized, goal-oriented training plan, delivered by trained humans inside a community, is selling something that does not commoditize the same way. The next decade rewards alignment with usage and outcomes, not signups and absenteeism.
The Strength and Conditioning Pendulum
The second shift is happening inside programming itself. The 2000s were cardio-led: treadmills, ellipticals, group cycling. Then strength training started to dominate the peer-reviewed literature, and brands pivoted hard. Some pivoted too hard, building entire concepts around strength only and quietly cutting conditioning out of the program.
That is a mistake worth flagging. Conditioning, the kind that drives heart rate up and produces lactate, is what triggers brain-derived neurotrophic factor, supports hippocampal volume, and drives neuroplasticity. Brain health, not just muscular health. The brands that stayed disciplined about combining both modalities are aligned with where the longevity and cognitive-health conversation is heading.
"It was never one or never the other. It's always a balance of both."
-DEVAN KLINE
Single-modality concepts are vulnerable to the next pendulum swing. Hybrid concepts with periodization across strength and conditioning are not. That is a defensibility question hiding inside a programming choice.
AI and the New Trainer Economics
The third shift is the one most operators are already worried about, and the analysis cuts in an interesting direction. AI is going to commoditize a lot of what fitness businesses currently sell. Generic programming services, the trainer-writes-you-a-plan-for-$99 model, will struggle. So will most of the standalone nutritionist business. AI can build a periodized program or a meal plan calibrated to a member's data faster, cheaper, and arguably better than most of what is currently sold as a discrete service.
That sounds like bad news for the category. It is not, if you read it correctly. AI commoditizes the part of the trainer's job that was already weakest: writing the plan. It does not touch the part of the job that actually drives retention.
"AI is going to be able to empower our trainers to do more of what makes us human, to do more of what builds our community, and that is make the adjustments real time with you."
-DEVAN KLINE
In other words, AI handles the programming so the trainer can focus on accountability, in-person coaching, and the focus meetings where members reset goals. That is a leverage story, not a replacement story, but only for brands whose operating model is built around the human layer in the first place. Concepts built on app-based programming or self-service access have nothing to defend. Concepts built on relationships, community, and in-person training get more valuable as AI strips out the surrounding noise.
The strategic test is straightforward: ask what part of the brand AI makes redundant, and what part it amplifies. The brands worth paying attention to are the ones where the answer to the second question is most of the operating system.
The Cancellation Problem and the Reactivation Problem
The fourth shift is the one the industry feels but rarely talks about. The traditional HVLP model, short for high volume, low price (the gym economics behind brands like Planet Fitness), is built on a quiet assumption: that most members will not show up. Pricing is set low to maximize signups. Cancellation is engineered to be inconvenient. Reactivation campaigns are largely avoided, because reaching out to a lapsed member risks reminding them they are paying for something they do not use.
It is a profitable model on paper. It is also a model that depends on member disengagement as a feature, not a bug. Klein puts the structural critique bluntly.
"The number one company in our industry would prefer that you do not show up."
-DEVAN KLINE
Looked at over a longer horizon, a model that depends on members not using the product is fragile as consumer expectations move toward outcomes. Members who expect a result will not tolerate a brand that hopes they stay home, and the reactivation muscle that HVLP brands deliberately do not build is the same muscle the next decade requires.
Brands whose unit economics are aligned with usage have the opposite problem. They have to build that muscle from day one. Harder to operate, but the model that compounds.
The GLP-1 Question
The fifth shift has the longest tail. GLP-1 medications are reshaping the aesthetic-driven part of the fitness customer base. Some portion of the consumer who joined a gym to lose weight will, going forward, address that goal pharmacologically. That is not a debate. It is happening.
The strategic question is what fitness brands have actually been selling. A brand whose marketing has been almost entirely about how members will look is exposed to that substitution. A brand whose message is about transformation, capability, character, and community is not.
The industry's top-of-funnel message has overcorrected toward aesthetics for years, and the GLP-1 conversation is the bill coming due. Brands with a values-led, identity-driven message keep their members through the transition. Brands without one watch their funnel narrow. The diligence question is simple: would a brand's marketing message still resonate in a world where pharmacology handles the aesthetic side of the value proposition? If yes, the brand has a future. If no, it is selling something that is being substituted out from under it.
What Comes Next
The five shifts converge on the same observation. The brands that win the next decade are the ones whose model is already aligned with where the consumer is going: training over activity, results over access, community over commodity, transformation over aesthetics. The brands that lose are the ones whose unit economics depend on members not showing up.
That alignment is not something you can retrofit. It is either in the operating system, the trainer model, the cancellation policy, the reactivation playbook, the marketing message, and the programming philosophy from the start, or it is not. The category is having a moment. Not every brand inside the category is built for what the moment becomes.

FAQ
what is the future of the boutique fitness industry
The industry is consolidating around training rather than activity. Members increasingly expect periodized, goal-oriented programs and measurable outcomes, not just access to equipment. Brands built around in-person coaching, community, and accountability are positioned for that shift. Brands built around access alone are not.
how is AI changing the fitness industry
AI is commoditizing generic programming and one-to-one nutritionist services, both of which were largely standalone product lines. It is not replacing in-person training, accountability, or community. Brands whose operating model centers on the human layer get more valuable as AI handles the surrounding work. Brands selling app-based or self-service programming are exposed.
What is HVLP in the fitness industry?
HVLP stands for high volume, low price. It refers to the big-box gym model built on low monthly fees, high signup volume, and economics that depend on most members not using their membership. It is the model used by national chains like Planet Fitness, and it is the model most exposed to the shift toward outcome-driven training.
How are GLP-1 medications affecting the fitness industry?
GLP-1s are absorbing a portion of the aesthetic-driven customer base that gyms historically relied on. Brands marketed almost entirely on physical appearance are exposed to substitution. Brands built on transformation, capability, and community retain their relevance because they are selling something pharmacology does not replace.
