(01) The method

You don't need another app, another hype, another January. You need a room that expects more from you, coaches who actually notice, and people who show up at 6am when you don't feel like it. Heat Pressure Time. That's how steel is made. That's how you are.

Shoreditch — 06:12

TEMPER is a group of five athletic clubs built around one idea: train hard, recover properly, repeat for years. Strength floors that respect heavy lifting. Classes that are coached, not shouted. Saunas and cold plunges that aren't an afterthought.

From fourto ninety.

4°C
Cold plunge

Every degree
has a job.

Cold to reset. Cool to lift heavy. Warm to move well. Hot to recover. We design every TEMPER club around temperature, so each room does exactly what your body needs.

The coaches actually notice

I've been a member at four gyms in London and this is the first where a coach clocked my squat drifting and fixed it without me asking. Small thing. Changed everything.

Tempered plan with Kwame. No crash diets — just a plan I could stick to around twelve-hour shifts at the hospital.

6am crew for life

I joined for the sauna. I stayed for the people. The Tuesday 6am Forge class is basically my family now and they will text you if you skip.

Worth every penny

The recovery floor at Battersea alone is worth the membership. Plunge, sauna, repeat. My back hasn't felt this good in ten years.

JOJames O.Battersea · Member since 2021

Knockout is no joke

Freya's boxing class is the hardest 45 minutes of my week and I'm weirdly obsessed. Great music, proper technique, zero ego in the room.

The app is genuinely good

Booking, macros, my coach's notes and the door QR all in one place. Every other gym app I've used feels ancient now.

On my deadlift

Eight months of Forge and 1:1 programming with Arjun. From 80 to 140kg without a single tweak. The man is a wizard.

Clean, calm, serious

No queues for racks, nobody filming themselves at the dumbbells. Just people who train properly and say good morning. Love it.

train alone.

Run club every Sunday. Heat Games every season. A group chat that won't let you skip leg day.

Upcoming events

It started with14 people in arailway arch.

In 2019 Marcus Hale — a former rugby strength coach — rented one damp arch under the Peckham line, bought six racks at auction and put a sauna where the office should have been. Fourteen people came to the first class. Most of them still train with us.

Five clubs later the idea hasn't changed: serious training, proper recovery, and a room full of people who expect to see you tomorrow.
