Programme selection gets most of the attention when people join a gym. Attendance data suggests a duller variable matters more.
What the market is doing
UK fitness industry revenue reached £6.5 billion, up from £5.7 billion in 2024. Membership grew to 12.2 million, an 18% penetration rate, and annual visits totalled 679 million — a 10% increase.
Supply is expanding to match. The Gym Group has opened 60 sites since 2020 and plans around 20 more in 2026.
Why the visit figure is the interesting one
Visits grew faster than membership. Existing members are attending more often, which means retention and frequency are improving rather than the market simply adding January sign-ups who never return.
Frequency is the variable that determines results. A moderate programme attended three times a week beats an optimal one attended twice a month, and it is not close.
Where location enters
Every additional minute of travel is a reason not to go, and those reasons compound on the days when motivation is low — which are the days that determine whether a habit survives.
Expanding low-cost supply means the nearest gym is increasingly a legitimate choice rather than a compromise. For most people, choosing the closer facility over the better-equipped one twenty minutes further away produces more training, not less.
What the growth categories suggest
The fastest-growing activities are Pilates, mindfulness classes and functional training, reflecting a broader shift toward overall well-being.
These share a characteristic: they are lower-intensity, lower-injury-risk and sustainable over years. People stay with them.
They also need less equipment, which reinforces the location point — a small local facility can deliver these formats perfectly well.
A practical selection order
1. Distance from home or work. Realistically assessed, including the walk from parking.
2. Opening hours against your actual schedule. Not your intended schedule.
3. Whether it offers a format you will keep doing. The growth categories are growing for a reason.
4. Equipment and facilities. Genuinely last, unless you have a specific requirement.
With 18% penetration, roughly four in five UK adults are not members. The industry is finally competing on whether people stay rather than how many sign up — and choosing on the variable that predicts attendance is how to benefit from that.
