Inside Tri-Fit
Everything you need, none of the queues
We've packed the space with the kit and extras that make a real difference to your training, then capped our membership so you can actually use it.
Gym floor
A floor that's ready when you are
Racks, free weights, cable stations and machines for strength work, plus treadmills, StairMasters and bikes lined up under our arched windows. Everything you need for a complete session, without waiting around.
- Strength zone: squat racks, barbells, dumbbells and cable stations.
- Cardio kit: treadmills, StairMasters and bikes overlooking Caledonian Road.
- Coaches on the floor: help with form or a programme whenever you need it.
Combat zone
Hit the heavy bags
A dedicated space with heavy bags, pads and room to move. It's home to our Box classes, and open for your own bag rounds whenever the class isn't running.
- Heavy bags and pads for technique, power and conditioning.
- Box classes run here, coached from the ground up.
- The best stress relief in London after a long day.
Recovery
Private infrared sauna pods
Finish your session in your own private infrared sauna pod. No shared benches, no waiting: just your space to warm up, switch off and recover before you head home.
- Individual pods, so you recover in total privacy.
- Unlimited use on the Gym + Sauna and Gym + Sauna + Classes plans.
- Easy access: your pod access codes are sent to you by email.

Styku 3D body scans
The scales only tell you part of the story. Our Styku 3D body scanner measures your body composition accurately in seconds, so you can see exactly where you're changing and prove your progress.

- Body composition, not just body weight.
- Two scans included with every Semi-Private PT camp, at the start and the finish.

What does capped membership mean?

Two scans are included with every Semi-Private PT camp. Ask the team at reception about booking a scan on its own.
Are there showers and lockers?
Yes. Changing rooms, showers and lockers are available to every member.
