Seven classes a day across CrossFit, Strength, Conditioning, Gymnastics, Weightlifting and more. Expert coaching for all levels — from complete beginners to competitive athletes.
The same world-class CrossFit coaching that built our Surbiton community, now in Guildford. Every 55-minute class is fully coached, scaled to your level and built around a structured programme that delivers real results. CrossFit runs five days a week with morning and evening slots.


High-intensity, accessible sessions using straightforward movements to build fitness. No complex technique required — just effort and consistency. A great starting point for newcomers and a firm favourite with experienced members who want to push their engine.
The snatch, clean and jerk, coached properly. Our Friday evening Weightlifting class gives you 90 minutes to focus purely on the Olympic lifts in a relaxed, technical environment. Whether you want to improve your CrossFit performance or simply love lifting, this class will make you better under the bar.


A weekly dedicated session focused on bodyweight strength and movement quality. Pull-ups, handstands, ring work — coached methodically in a small group. Gymnastics skills carry directly into your CrossFit training and this class gives you the time and space to really develop them.
Every new member starts here. The Beginners Course is a three-week course with two coached sessions per week, designed to introduce you to fitness and the core movements we use in class. You'll learn to squat, deadlift and press in a small group at a relaxed pace, building the confidence and technique to get the most from regular classes from day one.


Our brand new Strength class runs every Thursday, built around compound lifts on the barbell alongside strength accessory work. Programming runs in five-week blocks so you can track real progress, and the first block focuses on the Push Press and Strict Pull-Ups. Thursday classes at GU1 run as Strength, so just book in as normal.
Structured free time. Open Gym gives you the space and equipment to train at your own pace, whether you're following our open gym programme, working on a specific skill, making up a missed session or putting in extra volume. Available to all members alongside their regular class allocation.

We're bringing CrossFit Kids to Guildford. The same fun, confidence-building sessions we run at Surbiton — designed for school-age children and coached with the same care and expertise we bring to every adult class.

A brand new class designed specifically for busy postpartum mums who want to return to training with their baby by their side. Each session includes a strength-focused circuit and an EMOM to build fitness, and everything is scalable so you can train at your own pace, wherever you are on your postpartum journey. Recommended for babies aged 3 to 9 months who are happy remaining in their buggy (positioned next to you throughout the class) or being held. Once babies are mobile and crawling, these classes won't be suitable for safety reasons.


Two separate programmes, each designed to support different needs — both allowing you to take part in regular training with confidence. Using the workouts already written in the app, we provide personal adaptations to suit you, so you can train safely and still feel fully part of the class.
A multidisciplinary health and performance clinic based right here at GU1. Services include Chiropractic, Osteopathy, Physiotherapy, Sports Massage, Exercise Rehabilitation, Ultrasound Diagnostics, Dry Needling and Medication Prescriptions — all under one roof, alongside your training.
