The UK fitness industry reached £6.5 billion in total revenue, up from £5.7 billion in 2024. Membership grew to 12.2 million people, an 18% penetration rate, and annual gym and leisure centre visits totalled 679 million — a 10% increase on 2024.
Those are strong numbers in a period when discretionary spending has been under pressure. What they contain is more interesting than the totals.
Visits grew faster than membership
This is the detail worth noticing. A 10% rise in visits against a smaller rise in membership means existing members are attending more often.
For anyone choosing a programme, that is a meaningful signal: the growth is not driven by January sign-ups who never return. Retention and frequency are improving, which usually indicates that what people are doing is working well enough to keep them coming back.
Where the demand is shifting
As fitness trends evolve, more people are focusing on overall well-being, producing growth in Pilates, mindfulness classes and functional training.
All three share a characteristic: they are lower-intensity, lower-injury-risk and more sustainable over years than the high-intensity formats that dominated the previous decade.
This is a maturity signal. A market where the fastest-growing categories are the ones people can still do at 55 is a market that has learned something about adherence.
Supply is expanding too
The Gym Group has opened 60 sites since 2020 and plans around 20 more in 2026. Operators do not build capacity into a shrinking market.
For consumers, expanding low-cost supply generally means better pricing and more location choice — the two factors that most reliably predict whether someone actually attends.
What to take from it when choosing a programme
Frequency beats intensity. The visit growth is the clearest data point here. A programme you attend three times a week beats a harder one you attend twice a month.
Consider the categories that are growing. Pilates and functional training are growing because people stay with them. Adherence is the variable that determines results, and it is the one most programmes ignore.
Proximity is a real factor. With more sites opening, the nearest gym is a legitimate selection criterion rather than a compromise.
Well-being framing is not marketing fluff. The shift toward mindfulness and recovery reflects genuine demand, and recovery quality is a limiting factor for most people training consistently.
An 18% penetration rate means roughly four in five UK adults are still not members. The growth has room to continue, and the shape of it suggests the industry is finally competing on whether people stay rather than on how many sign up.
