Common questions, direct answers.

If yours isn't here, ask in your intro. The coaches give straight answers.

Getting Started

A coaching-led strength & conditioning gym built around structured group training. Five locations across London. Every session is coached, programmed in cycles, and scaled to the person doing it.
Adults, typically 25 to 55, who want proper coaching and a structure to follow. Beginners, busy professionals, ex-athletes, parents, people training for life. We have members from 18 to 74.
No. Getting fitter is the point. Every session is scaled. You don't need prior gym experience, you don't need to know the movements, and you don't need to be confident. That's our job.
No. Coaches actively look out for new members. You won't be ignored or left guessing. Most people tell us the nerves go in the first couple of sessions. Everyone in the room started somewhere.
Yes. Training is scaled to you: load, range, pace, volume. Plenty of members join specifically to rebuild capacity. You won't be singled out or pressured.
Book an intro at your nearest gym. 30 minutes with a coach, in person or virtually. We talk through your goals, training history and any niggles, you see the space, ask anything, leave with a clear next step.
Yes. Drop-ins are £25, and we reimburse that £25 against your first month if you join. Most people prefer to start with an intro first. It's a more useful conversation.
Trainers, comfortable clothes, a water bottle. Showers and towels are at every gym. Lifting shoes, belts, wraps: bring them if you've got them, you don't need them to start.
Yes. A large percentage of our members started with little or no training background.

We coach movement from the ground up, focus on good habits early, and create an environment where asking questions is normal. No one is expected to keep up or perform movements they are not ready for.

You'll be guided into the right training track and supported as you build confidence.
Your first session is about orientation, not being thrown into the deep end.

You'll be welcomed, shown around, and coached through the session so you understand how things work. The coach will explain movements clearly, offer scaled options, and keep an eye on you throughout.

Expect to move, sweat a bit, and leave knowing you made the right call.
Usually a few sessions.

The movements start to make sense, names become familiar, and routines settle quickly. Most people feel properly at home within the first few weeks if they train consistently.

Consistency beats intensity early on.
By coaching properly.

Classes are structured, movements are demonstrated, and scaling options are clearly explained. Coaches actively watch and adjust technique during sessions.

We prioritise quality of movement and appropriate loading, no matter what your level.

Training

The difference is complexity, not effort. DELTΔ is structured strength & conditioning: accessible movements, clear structure, consistent progression. Athletica is the higher-skill track: Olympic lifting, gymnastics, more technical conditioning. Both are coached. Both are scalable.
Yes. Many members train across both. We'll guide you on the right mix based on goals and experience.
Athletica uses similar tools but with a more deliberate, structured approach. Programming is built for long-term progression, not random intensity. Coaching standards and movement quality matter more than chasing scores.
Intro to CrossFit is the on-ramp into Athletica: three sessions to learn the language, lifts and pacing. You don't need it to start at Gymnasium; jump straight into DELTΔ. Take the on-ramp later if you want to step up to Athletica.
Yes. Conditioning blocks regularly cover the strength, engine and pacing that Hyrox demands. We also run full-distance Hyrox Sims at all our gyms each quarter.
It's planned. Training runs in blocks with intent. Strength progresses week to week, conditioning builds capacity systematically. We don't program random workouts. The consistency is what drives results.
Yes, intentionally. Repeating movements and formats lets you measure progress and build confidence. You should see your scores move.
A coach-led warm-up, a strength or skill focus, a conditioning piece, and a cool-down. 60 minutes, scaling and pacing called by the coach throughout.
60 minutes. Warm-up, strength or skill work, conditioning piece, cool-down.
Class sizes are capped to keep coaching quality high. Typical class size is 10 to 16, depending on location and time slot. Peak slots fill faster, so booking 24-48 hours ahead is standard.
Three sessions a week is the sweet spot. Two will get you fitter. Four if you've got a goal. Coaches help you find the right cadence around your schedule and recovery.
Yes, actively. Coaching is hands-on. They watch your reps, fix loads, manage scaling, and step in when needed. That's the whole product.
Yes. Open Gym is included on every membership at every site. Times vary by location.
DELTΔ is Gymnasium's structured strength and conditioning track.

It focuses on accessible movements, clear structure, and consistent progression. Complexity is kept lower so effort stays high and results come from showing up regularly.

It's coached, repeatable, and designed for real life.
DELTΔ is not easy. It's accessible, well-designed, and highly effective for beginners and returners, busy professionals, and anyone who wants a strong base built on consistency rather than complexity.
Athletica is Gymnasium's higher-skill, higher-method track.

It includes technical lifting, gymnastics skills, and more complex conditioning. Programming follows longer-term progressions and rewards consistency.

Athletica is coached and scalable, but it assumes a base level of movement familiarity.

Safety & Injury

Yes, when coached properly. We prioritise technique, scaling and appropriate loading. Coaches intervene when needed. Training is challenging, never reckless.
Almost certainly. Tell us in your intro and the coaches will scale around it. We work with members managing back, knee, shoulder and post-surgical issues every day.
Often, yes, with modifications. We'll suggest alternatives that keep you training while the issue settles. If it's beyond what we can manage in a class, we'll tell you that too.
Yes. Our members run from 18 to 74. The 50+ group are some of our most consistent and capable. Strength training is one of the best things you can do at any age.
You'll get an alternative that delivers the same training effect. Scaling is normal and built into every session.
We work with pre- and post-natal members regularly. Coaches scale appropriately. Bring any clearance from your midwife or physio.
Yes. We rebuild capacity carefully and progress as you recover. No need to start where you left off.
Scaling is built into every session.

Weight, reps, movements, and pace can all be adjusted. Scaling is normal and encouraged.

Results

Strength and movement quality usually within 4 to 6 weeks. Body composition follows over the next few months alongside good habits. Consistency does the heavy lifting.
Yes, as part of a consistent training routine and sensible habits around food and sleep. Training alone won't out-run a poor diet, but it builds the engine and muscle that make fat loss work.
No. You'll get stronger, leaner and more capable. Building meaningful muscle takes years of focused work.
Yes. Stronger, more mobile, better-conditioned bodies do everything else better. Many of our members run, cycle, climb or play team sport alongside training.
Through performance data: weights, times and reps logged in our app, and how you feel in everyday life. Coaches benchmark you against where you started.
You pick up where you left off. Programming is designed to absorb missed weeks. No guilt, no penalty.
Improved strength, fitness, confidence, and energy. Body composition changes often follow.
Talk to a coach. We'll adjust your approach.
Within a group setting, yes. Scaling and guidance are individualised.
That's the goal.

Membership

No. Memberships are monthly. Cancel up to 7 days before your next billing period. No lock-in.
Standard memberships are rolling and monthly. Some discounted memberships (founder rates, intro offers) carry a 3 or 6-month minimum term. We'll always be clear about that before you join.
Rent, fit-out and operating costs vary by site. We price each location fairly and transparently, never to maximise margin.
Pauses are available for injury, redundancy or pregnancy (with proof). Long-standing members get an annual loyalty pause: 2 weeks at 2+ years, 4 weeks at 4+ years. We don't pause for general life admin. Keeping memberships simple is what lets us keep them affordable.
If you're 2+ years in, use your loyalty pause. Otherwise you can drop down to a cheaper membership for the period you're away, then move back up when you return.
Yes. Once a week at a sister site, with some restrictions where a gym is at capacity.
Better than a trial week: book an intro with a coach, plus a £25 drop-in if you want to feel a class before deciding. The £25 comes off your first month if you join.
Showers, lockers & towels. A vanity area with hairdryers, straighteners and free toiletries. Olympic bars, dumbbells, kettlebells, lifting rig, rowers, skis and bikes. Train properly, then get on with your day.
Class timetables vary by site and are available online.
