Our purpose is simple: to build the best gym in the world; a gym that improves our members’ fitness & health by combining expert coaching, intelligent programming & fun in a place where everyone feels they belong.

We are a strength, conditioning & mobility gym based around expertly coached group training. We know that getting fitter is better, easier to stick to & more effective when done together so our community is at the very heart of what we do.

We cater for all abilities; from people with limited experience but a desire to get fit, to those looking to add a technical & competitive element to their training.

Our large space, conveniently located off Clapham High Street, is stocked with top of the range equipment and great changing, showering & communal facilities with free towels & toiletries.

Gymnasium is the only certified B-Corp gym in the UK and recently appeared in Men’s Health as one of the World’s Best Gyms.

Athletica – mix of cardio, body weight and strength at high-intensity

Stronger – focusses on building fundamental strength with pushes, pulls and squats

Motion – flexibility, joint strength & stability

CrossFit – constantly varied mix of weightlifting, gymnastics & cardio at high-intensity

Olympic – technically complex, compound lifts

From loo rolls & energy suppliers to our Legends program & the red bar of shame we are committed to using our business as a force for good. We are proud to be the only B Corp gym in the UK.

Becoming a B Corp was a key objective for us to demonstrate our commitment to the community we serve, the staff members we support, and the environment we use.

To become a B Corp, we had to meet rigorous standards in five key areas: governance, workers, community, environment, and customers. We achieved this through a range of initiatives that we’re proud of, such as providing salaried positions in an industry dominated by hourly workers, creating an internal Coach Academy program for staff development, offering pay above industry average wages, and providing a range of other benefits.

We’ve also created programs to give back to the community, such as our Spartan program for underprivileged youth in collaboration with local charities and our free Legends classes for those over 60. We’re committed to reviewing significant suppliers and selecting those that meet our high standards, including Teemill, Eleiko, and Nocco. We also prioritize local alternatives whenever possible.

Finally, we’ve implemented charitable giving policies to support local charities through the generation of funds collected from no-show/late cancellation fees and our events.

Being a B corp puts us in the company of other well-known brands such as Patagonia, The Body Shop, Burton, Ben & Jerry’s, and Innocent, who prioritize sustainability and being a force for good in the world.

Thanks for being part of the journey.
