90kg Multi Gyms

What "90kg" means on a multi gym

Retailers use the figure in two different ways, and the difference matters more than any other number on the box.

A 90kg weight stack

The plates themselves add up to that weight: a column of plates on two guide rods that you select with a pin. The Pro Fitness multi home gym sold by Argos is this type - Argos gives the stack weight and maximum resistance as the same figure - and so is the Marcy Eclipse HG5000, which Fitshop sells with a 13-plate stack and selector pin.

Resistance from a smaller stack

The gearing can multiply or reduce what you feel. The Marcy MWM-4965 and MWM7119 both carry a 68kg stack, yet are sold on 90kg resistance because the arms multiply the load on the chest press. On the MWM7119 the preacher curl pad only reaches about 45kg. It works the other way too: the Marcy Club MKM-81010 below quotes 131kg from its stack.

So when you compare machines, check both figures. A full stack gives you its weight on direct-pull stations such as the low row; a resistance figure may only apply to one movement.

Two things stand out. A plate-stack home multi gym in this class is heavy - the York weighs 162kg built and the Marcy Club 167kg - and the plate steps vary a lot. Small steps make progress smoother: a jump of 7kg is a big leap on a curl or shoulder exercise, while 4.5-5kg is easier to add.

Is a 90kg weight stack enough?

For most people training at home, yes. It is roughly double the 45kg found on entry-level machines such as the York Aspire 420 or Homcom's 45kg gyms, and it is the jump that stops you outgrowing the frame within a year. The extra load counts most on the big movements - lat pulldowns, rows and leg work - where a 45kg stack soon runs out.

Where it can feel light is a strong lifter's leg work or a heavy pulldown. If that's you, look at a stack with gearing that adds load (like the 131kg Marcy Club), a pneumatic system such as the Finnlo Bio Force Extreme (up to 120kg in 2.5kg steps), or our heavy duty range. If you'd rather load a bar yourself, a smith machine home gym takes Olympic plates instead.

Exercises a home multi gym covers

The NHS advises adults to do strength exercises on 2 or more days a week that work the legs, hips, back, abdomen, chest, shoulders and arms. A typical machine at this level reaches all of those from one seat:

• Lat pulldown - the long bar overhead for back and biceps
• Press and butterfly (pec dec) - arms, often with a pin to switch between the two
• Leg extension and leg curl - the leg developer with foam rollers
• Preacher curl - a curl pad, usually removable
• Low row - the low station with a footplate, also used for upright rows and curls
• Triceps press and ab crunch - the top station with a rope or strap

Argos lists exactly this set for its own 90kg model, with a double pulley system. If you want to load a barbell too, our bench press multi gyms and weight bench multi gyms add a proper bench; for free-moving work, a cable crossover machine is the better tool. The NHS also has a simple guide to strength exercises if you're starting out.

Space, delivery and assembly

Floor space and ceiling height

Most of these frames stand 196-217cm tall, so check the ceiling first, especially under a low beam or roller door. Argos's answer for the Pro Fitness model is a training area of 3 metres around the machine and 0.6 metres of clearance above its 207cm height. Allow for the leg developer and press arms swinging out, not just the frame's footprint.

Weight and delivery

A home multi gym of this size arrives in several heavy boxes. Argos says its model comes in six cartons, the heaviest 62kg - the weight stack. That is a two-person lift, and the HSE's manual handling guidance is worth a read before you carry plates up a drive. Built, the whole unit weighs 160kg or more, so a ground floor or concrete slab is the safest place for it.

Assembly time

Plan for an afternoon. Argos reviewers report between about 3.5 and 6 hours, and several call it a two-person job; threading the cables takes the longest. Our leg extension gym machines are a simpler build if you only need the leg station.

How to choose a 90kg multi gym

• Stack or resistance: confirm whether the headline figure is the plates or a pulley figure, and on which station.
• Plate steps: 4.5-5kg steps (York, Marcy MWM7119) suit steady progression better than 7kg.
• Maximum user weight: 120-136kg is normal here; choose well above your own weight.
• Cables: look for a stated cable rating (Marcy quotes 907kg aircraft-grade) and a double pulley system for smooth travel.
• Safety: a shrouded stack keeps fingers away from the plates, and a stack lock (the Marcy Club has a combination lock) stops children using it.
• Steel frame: 50mm box steel or thicker, with a powder-coated finish for a damp outbuilding.
• Warranty or guarantee: Pro Fitness gives a 1-year guarantee and Fit4home a 1-year parts and labour warranty - read what each warranty covers.

FAQs

Can you build muscle on a 90kg multi gym?

Yes. Muscle grows from progressive overload - adding load or reps over time - and this much load gives most home users years of room, with a full body workout from one seat. The UK Chief Medical Officers' physical activity guidelines back regular strength training at any age.

Does the full stack weight apply on every exercise?

No. The gearing changes it station by station. On some machines the press feels heavier than the stack and the curl lighter - the Marcy MWM7119 hits its peak on the press but about 45kg on the preacher curl.

How much does the whole machine weigh?

Usually 160-170kg once built: the York 100kg model weighs 162kg and the Marcy Club 167kg. Power rod machines like the Bowflex PR1000 are far lighter at 59kg because there are no plates.

How tall a room do I need?

At least the machine's height plus room for the pulldown bar - Argos advises 0.6m above the 207cm Pro Fitness frame. With a low ceiling, compare heights: the York 100kg model stands 196cm, among the lowest here.

Can two people use it at once?

Not normally on a single-stack machine like these, as every station draws on the same plates. Two-stack frames such as the Body-Solid GDCC-250 (2 x 72kg) allow it but need far more floor space.
