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.
