This is the decision that shapes a strength floor more than any brand choice, and it is usually made on price per station rather than on who is going to use the equipment. Get it wrong and you either buy machines your members cannot load, or machines your members will not use.
The short answer: selectorised machines use a built-in weight stack and a pin — fast to change, safe to use alone, forgiving for beginners, and the right default for a mixed-membership gym. Plate-loaded machines are loaded with Olympic plates by hand — heavier at the top end, cheaper per station, no cables to inspect, and the right choice for strength-focused facilities and performance rooms. Most real gyms run both: selectorised for the circuit and the general floor, plate-loaded for the heavy corner. If you are fitting out with one budget, start selectorised and add plate-loaded as the membership matures.
Key takeaways
How the resistance gets onto the machine, and nothing else. Both guide the movement along a fixed path; both are strength machines rather than free weights.
A selectorised machine has a weight stack built into the frame. You move a pin to choose the load, and a cable and pulley system transfers it to the handles or pads. Everything is enclosed, nothing is loose, and changing weight takes about two seconds.
A plate-loaded machine has weight horns instead of a stack. You load Olympic plates onto them by hand. The resistance arm is usually a lever rather than a cable, so there is no cable to fray and far less to service — but you need plates, somewhere to put them, and the discipline to rack them.
| Selectorised | Plate-loaded | |
|---|---|---|
| How you load it | Move a pin in a weight stack | Load Olympic plates onto horns |
| Time to change weight | About 2 seconds | 15–60 seconds depending on load |
| Load ceiling | Limited by the stack supplied | Limited only by the frame rating and plates on hand |
| Smallest increment | Usually 5kg, or 2.5kg with an add-on | 1.25kg, or less with fractional plates |
| Wear parts | Cables, pulleys, stack pins — inspected routinely | Bushings and bearings; no cables |
| Floor space | Machine footprint only | Machine plus plate storage |
| Training alone to failure | Safe — nothing to drop | Safe on most designs; check the unload position |
| Cost per station | Higher | Lower |
| Best for | Mixed membership, circuits, rehab, inductions | Strength-focused rooms, performance, sports clubs |
Browse both ranges directly: selectorised equipment and plate loaded.
Kit for this: the deciding question is who uses the machine — a member on an induction plan, or a lifter chasing a number. It is rarely about the machine at all.

Selectorised, for most UK sites, and it is a throughput argument rather than a training one. A member on a general programme moves through a selectorised circuit without touching a plate, without needing an induction on loading, and without leaving anything on the floor.
The membership numbers make the case. ukactive's UK Health and Fitness Market Report 2026, published on 9 April 2026 with Sport England, 4GLOBAL and Grant Thornton UK, recorded 12.2 million members — 18% of the over-16 population — making 679 million visits across 5,842 facilities, with visits up 10% on 2024. That averages roughly 116,000 visits per facility per year. Huw Edwards, CEO of ukactive, summarised it as: "Consumer demand for the services provided by gyms, pools and leisure centres is growing year-on-year."
At that volume, the seconds spent loading and unloading plates are real capacity. So is the staff time spent re-racking them.
The counter-argument is real too. A strength-focused site, a sports club or a performance room will get more from plate-loaded: higher load ceiling, lower cost per station, and members who already know how to load a bar. Most well-specified floors end up with a selectorised circuit and a plate-loaded strength corner rather than choosing one.

No. This is the objection that stops facilities specifying machines, and the pooled evidence does not support it.
Haugen, Vårvik, Larsen, Haugen, van den Tillaar and Bjørnsen published a systematic review and meta-analysis in BMC Sports Science, Medicine and Rehabilitation (2023) covering 13 studies and 1,016 participants (789 men, 219 women). Their conclusion was unambiguous: "No differences were detected in the direct comparison of strength, jump performance and muscle hypertrophy."
What they did find is specificity. Strength in free-weight tests improved more with free-weight training; strength in machine-based tests tended to improve more with machine training. You get better at the thing you practise, which is an argument for matching the equipment to the goal, not for ranking one above the other.
There is a second argument for machines that has nothing to do with hypertrophy. Sandercock, Moran and Cohen, publishing in PLOS ONE (2022) from a cross-sectional study of 253,423 English adults, found that under the strictest reading of the UK Chief Medical Officers' guidance only 7.3% of men and 4.1% of women met the muscle-strengthening recommendation. On the most inclusive definition it rose to 29% and 24%. Whichever reading you take, most adults do no resistance training at all — and a pin-loaded machine is a far lower barrier to entry than a loaded barbell.
The NHS physical activity guidelines for adults aged 19 to 64 ask for strengthening activities working "all the major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms) on at least 2 days a week". A selectorised circuit covers that in twenty minutes with no coaching.
The same one, which is the most useful fact in this whole comparison. ISO 20957-2:2024, published on 19 September 2024, "specifies safety requirements for stationary strength training equipment, in addition to the general safety requirements of ISO 20957-1", and applies to equipment "with stacked weight resistance or alternative means of resistance, such as elastic cords, hydraulic, pneumatic, electrical, magnetic, springs and externally loaded weights".
"Stacked weight resistance" is selectorised. "Externally loaded weights" is plate-loaded. Both sit under one document, so a supplier cannot claim one type is inherently held to a lower bar than the other.
What differs is the class. ISO 20957-1:2024 defines Class H as "intended for use in private homes", Class S for "training areas of organizations such as sport associations, educational establishments, hotels, clubs and studios, where access and control are specifically regulated by the owner", and Class I as inclusive professional use, which must also meet everything required of Class S.
Ask any supplier which class each machine is declared to, in writing, before you sign a fit-out order. It is a one-line question that separates commercial equipment from home equipment sold as commercial.

Shop strength equipment → Call 0333 880 3211Plate-loaded is cheaper per station to buy, and cheaper to keep running. Selectorised costs more up front because you are buying the weight with the machine, and it has consumables that plate-loaded does not.
A selectorised machine arrives with its resistance built in — typically 60kg to 120kg of steel per station, engineered, guarded and cabled. A plate-loaded machine is a frame and a lever. If you already own plates, the cost difference is substantial across a twenty-station floor.
Running cost is where the gap widens. Cables and pulleys are wear parts. For a commercial site that is not optional maintenance: the HSE's guidance on the inspection of work equipment under PUWER regulation 6 requires inspection "after installation and before first use" where safety depends on installation conditions, and "at suitable intervals, where work equipment is exposed to conditions causing deterioration liable to result in dangerous situations". The interval is "determined through risk assessment, taking account of the manufacturer's recommendations, industry advice and your own experience", and records must be "kept at least until the next inspection of that equipment".
Plate-loaded machines still need inspecting, but there is less to fail. Bushings and bearings wear slowly and visibly; a steel cable frays from the inside out, so the damage you can see is a late warning.
| Cost factor | Selectorised | Plate-loaded |
|---|---|---|
| Purchase per station | Higher — the weight is part of the machine | Lower — frame only |
| Additional purchase | None | Olympic plates and storage |
| Consumables | Cables, pulleys, stack pins | Bushings, bearings, grips |
| Inspection burden (PUWER) | Higher — cable integrity is critical | Lower — no cables |
| Downtime risk | A failed cable takes the station out | Rare; usually cosmetic |
| Resale | Strong for known commercial brands | Strong — less to go wrong |
Kit for this: if you are pricing plate-loaded, price the plates in the same breath. A twenty-station plate-loaded floor needs a lot of steel, and it is not in the machine quote.

Nautilus is the deepest range we carry, at 104 machines across both types. It is also the oldest name in the category: Core Health & Fitness, which owns the brand, describes Nautilus in its House of Brands as having spent 50 years on "biomechanics that complement natural human movements".
Nautilus runs several lines. Impact and Inspiration are selectorised single stations; Instinct is the selectorised commercial line; HumanSport is a compact selectorised range designed for smaller footprints; and the Leverage and plate-loaded machines cover the heavy end. Nautilus is supplied on a quotation basis, so pricing is confirmed per project rather than listed.
Alongside Nautilus we carry Attack Fitness (29 products) and MYO Strength (15 products) in the selectorised category, both listed with published prices — multi-station gyms from £6,670 to £14,120 and single stations from £1,150.
| Range | Type | Typical use | Pricing |
|---|---|---|---|
| Nautilus Impact / Inspiration | Selectorised single stations | General commercial floor | On request |
| Nautilus Instinct | Selectorised, commercial line | High-traffic health clubs | On request |
| Nautilus HumanSport | Selectorised, compact | Studios and small footprints | On request |
| Nautilus plate-loaded & Leverage | Plate-loaded | Strength and performance rooms | On request |

Usually neither, and this is the honest answer even though we sell both. A rack, a barbell and plates cover more of a home training programme for less money than any single machine, and they take less floor space than a multi-station.
The exception is a specific gap. If you want a leg press, a lat pulldown or a hack squat — movements a rack cannot replicate — then a machine earns its footprint. In that case plate-loaded is normally the better home purchase: you already own plates, there is nothing to service, and the load ceiling is whatever you can carry.
A compact selectorised multi-gym makes sense where several people of very different strengths share the space and nobody wants to change plates. The MYO 3 Stack at £5,160 is that machine.
Our own order history reflects this. Across our first 62 orders, every strength purchase has been free weights, racks or attachments — barbells, plates, kettlebells, benches, cable handles. The single largest order we have shipped is one Jordan bench at £1,554. UK home buyers are building around a rack, not around a machine.
If that is you, start with our home strength gym setup guide and the Jordan power racks and rigs guide, then add a machine only for the movement you cannot cover.
What does "selectorised" actually mean? It means the resistance is a built-in weight stack selected with a pin, rather than plates you load by hand. The term comes from the selector pin itself. A selectorised machine is self-contained: the weight, the cables, the pulleys and the guarding are all part of the frame, so nothing is loose and changing load takes about two seconds.
Is plate-loaded better for building strength? Not inherently, but it has a higher ceiling. A selectorised machine is limited to the stack it was supplied with, typically 60–120kg per station; a plate-loaded machine is limited by the frame rating and how many plates you have. For a lifter who has outgrown a stack, plate-loaded is the only way to keep adding load on that movement. For everyone below that point, the two are equivalent.
Which is safer to train on alone? Both are safe by design — that is the main advantage machines have over free weights. Selectorised has a slight edge because there is nothing to lift, carry or drop, and failing a rep simply returns the stack. On plate-loaded machines, check the unload position before buying: a machine that requires you to strip plates from an awkward angle at the end of a hard set is a poor design regardless of brand.
How much floor space does each need? Selectorised needs its own footprint plus access on the working side. Plate-loaded needs the same, plus plate storage within a few steps — a plate tree or horns on the machine itself — and clear floor for loading. Budget roughly 20–30% more total area for a plate-loaded station once storage and loading space are counted, which often cancels the purchase-price saving in a small room.
Can you mix selectorised and plate-loaded on the same floor? Yes, and most well-specified gyms do. The common pattern is a selectorised circuit sized for induction members and general traffic, plus a plate-loaded strength area with leg press, hack squat and a couple of leverage stations. Keep them physically separated so plate traffic does not cross the circuit route.
Do these machines need servicing, and how often? Yes, and the interval is not fixed. HSE guidance under PUWER regulation 6 says the frequency is determined through risk assessment, taking account of the manufacturer's recommendations, industry advice and your own experience, with records kept at least until the next inspection. In practice selectorised machines get a monthly cable and pulley check; plate-loaded machines get a bushing, bearing and fixing check on the same cycle with far less to find.
Why is Nautilus quoted rather than priced online? Nautilus commercial equipment is supplied on a project basis, so the price depends on the specification, quantity and delivery for that particular fit-out. Send us the station list or the floor plan and we will come back with a full quotation. Attack Fitness and MYO Strength are listed with published prices and can be ordered directly.
Start with who is using it. A broad membership on general programmes wants selectorised. A strength-focused room, a sports club or an experienced home lifter gets more from plate-loaded. A gym with both populations should buy both, and separate them on the floor.
Then check the class declaration and the plate budget, in that order. Class S or I under ISO 20957-1 for anything commercial, and a realistic figure for the steel a plate-loaded floor needs before you compare quotes.
