What we do

HYROX-style hybrid training for anyone 18 and over, combining strength, endurance, and functional fitness. But that’s just the foundation. What really sets us apart is everything around it.

You won’t find a more welcoming and friendly bunch of people.

Our members love to train together, pushing themselves - and each other - every step of the way.

The Engine Room is more than a gym. It’s our happy place.

Our community

We genuinely believe they’re the best in the business.

They keep training varied, engaging, and most importantly fun, while supporting every member on their fitness journey.

With HYROX judging experience too, they’ll keep you on track.

Our coaches

HYROX 365 programming builds fitness that lasts.

Blending strength, endurance, and functional training, every session has purpose and keeps things fresh, challenging, and above all, fun.

Built to make you stronger, fitter, and ready for anything!

Our programming

Our official HYROX kit, supplied by Wolverson Fitness, brings a true competition-standard feel to every session.

Built to race day specs, you’ll train with the same sleds, weights, and equipment used in HYROX events worldwide.

Get the edge in our HYROX Training Zone.

Our kit

And it doesn’t stop there. We’ve got great running routes right on the doorstep, we’re easy to access (with free parking for members and Chichester train station next door), and every session ends with a catch-up over a cuppa. Perfect.

Our classes

The Engine Room is your home for HYROX-style training combining strength, endurance and conditioning to build fitness.

With coached sessions running before work, at lunchtime, after work and on weekends, it’s easy to fit training around your schedule. Plus, classes are capped at 16 people (8 for our strength and beginner sessions), ensuring plenty of coaching support and room to train.

Following the HYROX365 methodology, our classes blend HYROX-specific training and conditioning with strength to develop power and resilience.

Foundational: A refined, circuit-based session designed to build a strong, balanced foundation across strength, endurance and movement quality.
Engine: A performance-driven conditioning class focused on elevating your aerobic capacity, speed and endurance so you can sustain high output with control.
Power: A progressive strength session engineered to develop power, resilience and the ability to perform under fatigue - building the strength that underpins race performance.
Complete: A fully integrated, race-specific experience combining strength, conditioning and HYROX movements to prepare you for the physical and mental demands of competition.
Developing the power behind performance, this is a strength-focused class built on key compound lifts to develop the power, strength, control and durability needed to perform at your best in HYROX and remain injury free.
Finding time to train can be a challenge when life and work get busy.
That's why we've created Lunchbox ROX - a high-energy 30-minute workout designed to fit into your lunch break.
If you work in Chichester, join us at 12:15pm every Monday, Wednesday and Friday. You'll get a great workout in, enjoy a freshen-up in our (pretty incredible) showers, and be back at your desk before the afternoon kicks off.
£10 per session. Free for members.
Whatever your starting point, there’s a class for you at The Engine Room.
Whether you’re completely new to exercise, getting back into a routine, or simply curious about HYROX, our beginner classes – the Platform programme - are designed to help you build fitness and confidence, learn the fundamentals, and progress at your own pace. The groups are smaller (a max. of 8 people) so that you get all the coaching support you need.
You’ll then progress into our HYROX and Strength sessions when you’re ready.
If starting here, we suggest you start with one of our Flex Engine membership packages.

And on Sundays we mix it up! Our HYROX sessions take on a mini sim-style format, making them perfect for anyone looking for a HYROX taster or some valuable pre-event prep.

Planning a doubles event? It's a great chance to practice your transitions together. Come down and train with the same kit you'll be using on race day. We're here to help you feel as prepared and confident as possible.
