Gymnasium — 5.0 from 800+ Google reviews

"I'd usually get anxious starting at a new gym but Tom and Sós made me feel so welcome from the get go."
— Alexandra, Gymnasium Kennington

"Classes where people actually talk, coaches who know your name and coffees after class."
— Jessica, Gymnasium Twickenham

"Can't describe how great this gym is. Both challenging and fun. Started as a beginner a few months ago and have come a long way because of the coaches at Gymnasium. The community this gym offers also couldn't be better. Always something in the calendar to look forward to and the other members are all a class bunch."
— Grayson, Gymnasium Brixton

"I'd moved to London from Ireland so I didn't know anyone. The atmosphere in the classes are brilliant, the coaches are so welcoming and the style of classes are a really great way to meet people."
— Sarah, Gymnasium Brixton

What Gymnasium is

Somewhere to train, and somewhere to grow.

Class-based sessions in Brixton, Kennington, Wandsworth, Ealing and Twickenham, each one coached and programmed in cycles: strength, conditioning, CrossFit, HYROX and run club, all scaled to the individual. You get stronger, you learn real skills, and you do it with coaches people genuinely rate.

The social side

It's not just lifting weights.

Monthly Sweat & Socials at every gym. Bigger events each quarter, outdoor workouts through the summer, run clubs from easy to competitive, social cycle rides, and a couple of all-gym days a year. The rest we can't take credit for: members sorting their own coffees after class, weekend walks, even ski trips.
