About Gymnasium

Gymnasium is a coaching-led strength and conditioning gym group with five locations across London (Brixton, Kennington, Twickenham, Wandsworth and Ealing) built around expert coaching, planned programming and a strong community, whatever your starting point.

What makes us different

Every class is coached
Programming follows structured, purposeful blocks rather than random workouts
Community is designed in, not incidental

B Corp certified

Independently verified across governance, workers, community, environment and customers, written into how the business operates, not just a badge.

Affiliations

Registered CrossFit Affiliate and certified Hyrox partner gym across all locations.

Personal training

We don't offer 1:1 PT: group coaching plus weekly skills clinics and Open Gym give the same individual attention within a stronger group dynamic.

Facilities

Showers with body wash and shampoo provided, hair dryers/straighteners, towels, changing-room essentials, water stations, and vending machines for shakes, bars and energy drinks.

Class length

An hour on the clock, about 40 minutes of actual training once warm-up and cool-down are accounted for.

Results

Most people feel better within a few weeks: energy, sleep and day-to-day feel tend to move first, with visible physical change following consistent training. Progress shows up in performance and how movements feel, not just the scale.
