The first six machines you put on a gym floor shape everything that follows: circulation, supervision workload, maintenance budget and, in the end, how members judge the room. Get that core right and specialised stations can be added season after season. Get it wrong and you spend years working around a layout that fights you.
This guide is written for professional buyers: gym operators, cross-training box owners, hotel and campsite managers, local authorities, clubs, schools and rehabilitation centres. It covers six machines that together address cardiovascular work and the main muscle groups on a moderate footprint, without spending on stations that will stand idle.
Specification comes before brand
Equipment installed in a facility open to members, guests or the public is not the same product as equipment sold to an individual. Indoor fitness equipment for professional installations falls under EN ISO 20957-1 class S. Class S is the club and studio specification: frames, bearings, upholstery and cable systems are dimensioned for continuous multi-user duty cycles rather than occasional sessions.
One point is regularly misread. Class I is not a tier above class S. It is a professional class intended for inclusive access, for users with reduced mobility. It answers a different question, not a higher one. Before comparing prices, ask every supplier which class each frame is certified to.
1. The treadmill
The treadmill is the machine members reach for first, and the one that decides whether the cardio zone feels busy or empty. Its appeal is simplicity and comfort: no learning curve, no supervision required for a first session, immediate results in calorie expenditure. It also doubles as a cross-training station, used for intervals, walking recovery or incline work rather than steady running alone.
On a professional floor, the deck, the motor duty rating and the belt are the parts that age. Specify them for the number of hours the room is actually open, not for an average session. Our range is grouped under professional treadmills.
2. The exercise bike
The bike is the low-barrier machine of the cardio zone. It suits members who want to train without a heavy sweat load, older users, and anyone returning after an interruption. Resistance is adjusted step by step to the user, which makes it the easiest machine to prescribe on a first visit and the one that generates the fewest incidents.
It is a lower-body dominant machine and should be positioned as such in your programming; pairing it with an upper-body station is what turns it into a full session. Upright and recumbent formats are listed under professional exercise bikes.
3. The rowing machine
The rower is the answer for members who are short of time. A meaningful session is short because the movement recruits legs, trunk and upper body in one chain, which is also why it is the single best value cardio purchase per square metre. Where a treadmill trains one pattern, the rower trains a full-body pattern.
It does demand technique. Budget for a short induction, or the machine will be used badly and quietly abandoned. See the professional rowing machines range.
4. The leg press
The leg press is the strength station with the widest user range on a mixed floor: it loads the lower body heavily while keeping the spine supported and the movement guided. That combination is what allows a facility to serve a first-time member and an experienced lifter on the same machine without supervision on every set.
Vertical formats save floor area where space is the constraint; see vertical leg press machines.
5. The lat pulldown
The lat pulldown covers the back and the pulling pattern that free-weight beginners almost never train correctly on their own. Selectorised load means the weight change takes two seconds, which matters far more on a busy floor than the theoretical superiority of a barbell alternative.
6. The seated chest press
The seated chest press completes the pair: pushing pattern, chest and shoulders, back supported, no spotter required. With the lat pulldown and the leg press it gives you a three-station strength core that covers push, pull and legs. Everything else, over the following years, is a refinement of that base. The full catalogue sits under selectorised strength machines.
And the cross trainer?
The cross trainer is the machine most often added as a seventh. It is the most comfortable cardio machine to use, it is joint-friendly, it supports interval work and multiple built-in programmes, and it engages the upper body as well as the legs. If your membership skews towards low-impact training, it makes a strong case for replacing one of the two bikes in the initial order rather than being added later. It is listed under professional cross trainers.
Frequently asked questions
Is six machines enough to open a facility?
Six machines cover cardiovascular work and the main muscle groups, which is enough to run a credible general offer. It is a starting core, not a finished floor: specialised stations are added according to the public you actually receive, once you have real attendance data rather than assumptions.
How many units of each should I order?
That depends on your peak occupancy and your opening hours, which only you can measure. We size quantities during the quotation, from your floor plan and your expected attendance, rather than applying a ratio that would not fit your room.
Can I mix cardio and strength brands?
Yes, provided every frame is certified to EN ISO 20957-1 class S and you accept two service contacts instead of one. In practice, most operators standardise the strength line first, because its parts stay in service the longest.
What should I check before signing?
The certification class of each frame, the warranty on structure versus wear parts, the spare-parts availability period, and who performs the installation. Those four lines explain most of the cost difference between two apparently similar offers.
Equipping your floor
The right first order is the one built around your room, your opening hours and the public you serve, not around a generic list. Send us your floor plan and your intended programming and we will size the core, the quantities and the layout with you: request a quote.
