Fitness classes

A/B Circuits
A circuit that alternates between two groups of stations, so you get strength work and conditioning without standing still. Thirty minutes flat, which makes it the easiest class in the timetable to fit into a lunch break. Chris sets loads per person, so mixed abilities train together comfortably.
Membership:
Abdominal Circuits
A circuit built entirely around the core: stability holds, rotation work, lower-abdominal exercises and higher-intensity stations. The real benefit isn't how it looks, it's better posture and a back that complains less. Livvy scales every exercise. Friday, 6.15am.
Membership:
Able Collective Strength
A strength class built to adapt around whoever turns up. Alison works on functional strength and general fitness, adjusting every exercise so the session fits you rather than the other way round. Confidence comes first and load comes second.
Membership:
Boxing
Technical coaching on the pads and bags, combined with the conditioning work that makes boxing such good fitness. Alex takes it from the basics, so you can arrive having never thrown a punch. No sparring unless you ask for it. Gloves available to borrow.
Membership:
Brazilian Jiu Jitsu
Brazilian Jiu-Jitsu is a grappling art focused on ground fighting, leverage and control rather than striking. Adam builds a proper technical foundation through drills and setups, so complete beginners aren't thrown in with experienced grapplers. Seventy-five minutes, twice a week, up to twenty on the mats. Compete if you want to; most people don't.
Membership:
Calisthenics
Strength training using your own bodyweight: pull-ups, dips, holds and progressions towards the harder skills. Every movement has an easier version, so you start from what you can do today. Tristan and Alex keep groups to eight. An hour, Monday, Wednesday Thursday and Friday Evenings
Membership:
Circuits
A circuit of stations mixing strength, resistance and cardio, with a timer telling you when to move on. You work at your own pace at each station, which is why the class handles mixed abilities well. An hour with Livvy, twice a week at 7am.
Membership:
Freestyle Calisthenics
The creative end of calisthenics: momentum drills, swing control and dynamic bar transitions strung together into flows. This one does assume some bodyweight strength already, so start with our standard calisthenics class if you're new to bars. Tristan takes it, eight people, Monday evenings.
Membership:
Functional Fit
Multi-joint movements using kettlebells, dumbbells, resistance bands and bodyweight, chosen because they mirror what everyday life asks of you. The aim is better mobility, a stronger back and fewer tweaks and strains. An hour with Nabel, Wednesday mid-morning.
Membership:
HIIT
Bodyweight and cardio intervals that build fitness, strength and agility at the same time. Livvy gives an easier version of every movement, and the interval format means the rest is built in, which makes HIIT far more beginner-friendly than the name suggests. Monday, 7am.
Membership:
Hypertrophy
A coached session aimed squarely at building muscle: progressive overload, isolation work and controlled time under tension, programmed rather than made up on the day. Chris keeps it to six people so form actually gets watched. Forty-five minutes, Wednesday evenings.
Membership:
Hyrox Training
HYROX is eight rounds of a 1km run followed by a functional station: sled, ski, burpees, carries, wall balls. These sessions train exactly that, scaled to what you can currently do. Plenty of members come for the fitness and never enter a race. If you do want to race, Kate will get you ready. Three sessions a week including two at the weekend.
Membership:
Kids Boxing
Alex teaches young people the fundamentals: stance, footwork, how to throw a punch properly, and the fitness and movement that go with it. It's a supervised, supportive class, and the confidence tends to arrive alongside the technique. No experience needed.
Membership:
Kids Calisthenics
Kids learning to control their own bodyweight through gymnastics-style drills, pull-ups, press-ups and balance work. No heavy weights, and a coached, supervised environment throughout. It builds real strength, better posture and coordination, and the sort of movement habits that stick. Forty-five minutes with Tris, Monday evenings. £5 per child
Membership:
Kids Muay Thai
Muay Thai for children: striking technique using hands, elbows, knees and shins, taught with the discipline and respect the sport is built on. Steve runs a controlled class suitable for a complete beginner or a child who already trains. Forty-five minutes, Friday after school, up to sixteen.
Membership:
Ladies Muay Thai
A women-only class drawing on boxing and kickboxing: striking technique, pad work and conditioning, with enough to think about that the hour goes quickly. Most people arrive with no experience at all and the group is used to it. Steve takes it, eight people, Wednesday evenings. Gloves available to borrow. There's also a separate sparring class if you want to take it further.
Membership:
MMA
Mixed martial arts: striking, takedowns and submissions, with the focus on the transitions between them. Will coaches technique before intensity, so there's a way in whatever your level, and there's no obligation to spar or compete. An hour, twice a week, eight people. Gloves available to borrow.
Membership:
Muay Thai
Muay Thai uses fists, elbows, knees and shins, plus clinch work, which is why it's called the art of eight limbs. Steve teaches it as a discipline as much as a workout, and takes complete beginners through the stances and basics properly. An hour, twice a week, up to sixteen. Gloves available to borrow. There's also a separate sparring class if you want to take it further.
Membership:
Muay Thai Pad Blast
Pad work built on simple, repeatable techniques, so you spend the session hitting things rather than learning combinations. It's one of the better ways to get your heart rate up without it feeling like a workout. No experience needed and no sparring. Steve takes it Monday evenings, up to twenty.
Membership:
Olympic Weightlifting
A proper weightlifting club teaching the snatch and the clean & jerk through a step-by-step technical model, with strength built as you keep coming back. We're British Weight Lifting affiliated, and the club runs from complete beginner through to active competitor. Chris takes it Monday evenings, ten people.
Membership:
Pilates
Pilates builds strength from the core outwards, with a lot of attention on control and posture. You'll stretch out muscles, tendons and ligaments and end up moving more easily in everything else you do. Danielle takes it Saturday mornings, forty-five minutes, eight people.
Membership:
SHRED
High-intensity interval stations and aerobic drills, run at pace. It's one of the harder classes in the timetable and Chris doesn't pretend otherwise, but every station scales and you set your own effort. An hour, Monday and Thursday lunchtimes.
Membership:
Spin
Forty-five minutes on the bike working through endurance, speed, intervals and recovery. The thing that matters for a first-timer: you set your own resistance, so nobody can tell whether you're taking it easy. Someone will set your bike up properly before you start. Twice a week, twenty-three bikes.
Membership:
Strength Training
A structured session built on the compound lifts — squat, hinge, press, pull — with progressive loading and real attention to technique. Learning these properly with a coach is far quicker than working it out from videos, and considerably safer. Nabel takes it Thursday mid-morning, an hour, ten people.
Membership:
Stretch & Mobility
Guided stretching and mobility work: longer restorative holds combined with drills that improve how you move. It's the class that makes everything else you do feel better, and the one most people skip. Renana takes it Thursday evenings, forty-five minutes.
Membership:
Underground Athletes
A performance class built on a proper programme rather than a new session made up each week. Greg works through strength, fitness, speed and general athletic ability, progressing the load and the complexity as you go. It suits anyone who wants their training to build towards something rather than just leave them tired.
