FOR the EVERYDAY ATHLETE.

HIGH Performance GYM facilities & Classes

Join the fitness club where everyday athletes come to train with purpose — and never train alone. ONE LDN is more than a gym. It’s a high-performance community built on real connection, serious training, and a crew that shows up for each other.

With premium gym facilities in Chelsea and Fulham, strength, conditioning and recovery classes running daily, elite coaches, and London’s leading HYROX training space, we’ve created a space where performance meets play — and consistency turns into progress.

Proudly backed by Nike®️, voted Best Gym on ClassPass three times and home to London’s everyday athletes.

The Playground

A dedicated 2,000 sq ft performance arena built for functional, hybrid, and strength training. This isn’t a space for soulless workouts, it’s a high-energy environment engineered for real connection, grit, and group training
The Gym

Built for strength. Free weights, Olympic weights and a full range of cable and strength machines. Whether you’re building muscle, pushing for PBs or making sure a strength foundation supports your training, this is where the work gets done.
HYROX TRAINING

A dedicated sled track and treadmill area, plus HYROX classes built to get you race-ready. Our signature HYROX 90 sessions offer longer partner workouts designed to build your engine, strength endurance and race-day performance
Unlimited Classes

Our signature classes, including HYROX, WOD, Built, Pilates, and Yoga, are designed to challenge, elevate and transform. All sessions are expertly programmed and delivered by our elite coaches, running at a range of times, daily.
Elite Recovery

Four Ice Baths, two Saunas, Normatec boots and Hyperice recovery tech. Recovery isn't an add-on, it's part of the training. Everything you need to reset, so you can keep pushing.
The Studio

Daily Pilates and Yoga classes built to enhance mobility, flexibility, posture and core strength. Low-impact & high-value, these sessions can supplement your training, keep you moving well, and reduce your risk of injury.
Train with mates

No one trains alone here. Free weekly events, big team sessions like HYROX 90 and Sunday Sweat, and one free guest pass every month to bring your mates along. Train with people who push you further, and leave with new mates.
The Bar

Pre-fuel and refuel at The Bar, with a selection of shakes, coffee, matcha and a curated line-up of performance and hydration brands. Order ahead, pick up when the session's done.
