4°Cold
plunge
Slate pools held at 4°C. Two minutes, slow nasal breathing, total reset. Guided Cold Start sessions every morning.
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.
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.


















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.

4°Slate pools held at 4°C. Two minutes, slow nasal breathing, total reset. Guided Cold Start sessions every morning.
18°Kept cool for heavy days. Competition racks, oak platforms, calibrated plates and room to actually move.
26°Warm, calm and precise. Oak reformers, twelve people max, instructors who correct every rep.
38°Infrared panels warm muscles, not the air. Mobility, yoga and long holds that open you up.
90°Finnish cedar, 90°C, löyly on the hour. Pair it with the plunge for our Fire & Ice protocol.
The three things that turn raw iron into steel. We just built clubs around them.
See the classesEvery class is programmed by our head coaches in 8-week blocks, rated for heat from 1 to 5, and capped so a coach can see every rep.
Barbell strength in 8-week blocks. Squat, hinge, press — coached to the millimetre, loaded with intent.
Pad work, bag rounds and footwork drills. Real boxing technique, zero ego, loud music.
Power-zone intervals on the bike with a live leaderboard. Lights down, output up.
Forty metres of turf, heavy sleds and short rests. Hybrid race prep for people who like to suffer well.
Infrared mobility and long-hold yoga. Opens hips, calms the nervous system, undoes the desk.
Kettlebell complexes, carries and ballistic power. Grip strength for life.
Row, ski and bike intervals built on heart-rate zones. The aerobic base everything else sits on.
Precise reformer pilates for strong trunks and bulletproof joints. Slow is harder than it looks.
Guided breathwork then a coached plunge. The calmest you'll feel before 7am.
Three rounds of sauna and plunge, timed and guided. Contrast therapy done properly.
Live availability for the next seven days. Members book up to 7 days ahead in the app — spots release at 07:00 every morning.
Generic plans get generic results. With the Tempered membership you get a coach who builds your training and nutrition around your body, your schedule and your life — and answers within 12 hours.
See Tempered membershipA 60-minute session with your coach: goals, history, injuries, how you actually live. We scan, screen and test before we prescribe.
Training blocks built around the clubs and classes you love, plus macro targets that fit your culture, your kitchen and your calendar.
Log sessions and meals in the app. Your coach reviews every week, adjusts load and keeps you honest when motivation dips.
Every eight weeks we re-scan and re-test. Numbers, not vibes. Then we build the next block from where you really are.
38 coaches, all qualified to Level 4 or above. These four set the programming.







Arjun: Great squat single yesterday. We're adding 2.5kg today — keep the pause honest 💪


Morning! How did the knee feel on Sunday's run?
Much better. No pain at all on the 7K 🙌 Can we add intervals back?

Love it. Updated your plan: Engine Room Thursday, easy zone 2 Saturday. Sending you a form check for split squats 👇

No joining fee this month. Monthly plans roll with 30 days' notice — or go annual and save 15%.
One home club. Everything you need to train properly.
All five clubs, unlimited classes and the full heat & recovery floor.
Everything in All Clubs, plus a coach in your corner.
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.
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.

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

Booking, macros, my coach's notes and the door QR all in one place. Every other gym app I've used feels ancient now.
Eight months of Forge and 1:1 programming with Arjun. From 80 to 140kg without a single tweak. The man is a wizard.
No queues for racks, nobody filming themselves at the dumbbells. Just people who train properly and say good morning. Love it.

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

Open to members and their friends. Most are free — the ones that aren't go to the TEMPER Foundation's youth boxing programme.
