Talk to a squat rack specialist| Assembled Dimensions (L x W x H) | 203 cm x 170.4 cm x 211 cm |
| Frame | 16-gauge (1.5mm) powder-coated steel |
| Warranty | 12 Months Parts Replacement |
If you want a full strength setup in one footprint, the CORTEX SM-20 combines a Smith machine, power rack and adjustable cable station with a 45 kg pin-loaded stack you can expand to 100 kg with plates. The 16-gauge steel frame holds up to 200 kg on the pull-up bar and safety spotters, so it handles heavy compound work from day one.
It suits a home lifter who trains alone and wants both guided and free-weight options, with 10 height positions on the J-hooks, spotters and Smith bar to dial in squats, presses and rows. The included landmine attachment, dip handles, lat pulldown bar and pulley handles mean you can run a complete session without buying extra gear.
What jumps out is the 2:1 cable ratio paired with 10-position J-hooks and spotters: you can run heavy Smith work, then switch to smooth cable movements without resetting your whole station.
The 45kg stack is light for strong pullers, though it expands to 100kg with plates. At 181kg built, confirm the floor space is permanent, because this isn't something you'll shuffle around.

This single frame combines a Smith machine, power rack, adjustable cable pulleys and a multi-grip chin-up bar, so one footprint covers squats, presses, pulls and cable work.
For a home gym where floor space is limited, that consolidation does the heavy lifting of several separate machines.
What this means for you: One frame handles your full-body routine without buying and fitting out four separate machines.
The frame is built from 16-gauge 1.5mm steel with a powder-coated finish that resists scuffs and chips during loading.
At 181 kg net weight, the whole unit stays planted when you load it up.
What this means for you: The gauge steel and the load ratings mean it grows with the lifter rather than topping out early.
The Smith station runs a 203 cm guided barbell on 50mm Olympic sleeves, with 10 height positions to set the start and catch points.
The guided path is useful for solo accessory work when there is nobody to spot you.
What this means for you: The Smith bar guides the path for solo pressing and squatting; the free-weight rack is there when you want full range work.
Heavy-duty cables run adjustable pulleys at a 2:1 ratio for presses, rows, lat work and cable flyes, with the control cable rated to a 100 kg max load.
A 45 kg pin-loaded stack ships as standard and expands to 100 kg once you add plates.
What this means for you: Pin-loaded means you change resistance in seconds between sets; the plate-expansion path keeps it useful as you get stronger.
Two 350 mm safety spotter arms and two J-hooks move across 10 height positions, so you can set catch bars at the right point for squats and presses.
That matters most when you train alone and push close to failure.
What this means for you: Set the spotters a notch below your sticking point and you can train heavy solo with a backstop.
The rack arrives with a wide attachment set, so you can start a broad range of movements without buying extras.
Removable dip handles rated to 120 kg add a bodyweight station to the frame.
What this means for you: The included attachments cover dips, landmine presses, rows and lat pulldowns from day one.
The rack accepts 7ft Olympic or standard barbells and includes an upright holder for 50mm Olympic bars.
Four weight pegs keep your 50mm Olympic plates on the frame and within reach.
What this means for you: Plates live on the frame, so changing loads between free-weight and Smith work stays quick and tidy.
The SM-20 comes with a 12-month parts replacement warranty, handled locally so you deal with us.
On a 181 kg strength station, knowing parts are covered takes the guesswork out of the purchase.
What this means for you: If a component needs replacing in the first year, we sort it for you.

Effort: a two-person job, 7 assembly steps in the manual. Tools: a spanner and an Allen (hex) key (bolts and fixings are included).
It ships broken down across five heavy cartons (192 kg gross) on a freight service. Plan for someone to help move the cartons inside before you start building. We keep you across tracking from dispatch to delivery, so you'll know roughly when it lands rather than waiting on a surprise knock.
Take photos before you start assembly and email them to support@cardioonline.com.au within 48 hours of delivery. We lodge the freight claim, arrange replacement parts or a full unit, and stay on it until you're building. You never deal with the courier or manufacturer directly, that's our job to sort.
Set aside a proper block of time. The manual runs 7 assembly steps and recommends two or more people, mostly because the steel sections are heavy and awkward to hold square while you bolt them. You'll need a spanner and an Allen (hex) key; all bolts and fixings are included. The cable routing is the fiddly bit, so take your time there.
A 2:1 ratio means the handle moves twice as far but you feel roughly half the stack weight. The published unilateral ratio is 0.46, so the full 45 kg stack feels more like 21 kg at one handle, with longer, smoother cable travel. It suits higher-rep cable work, flyes and face pulls well. If you want more load later, the stack expands to 100 kg with added plates.
Assembled, it measures 203 cm long, 170.4 cm wide and 211 cm tall, so it clears a standard 2.4 m ceiling; leave headroom above the chin-up bar. Give yourself room around all four sides: space to rack a 7ft Olympic bar, step back for cable rows, and swing up to the multi-grip chin-up bar overhead.
It's a genuine all-in-one for a home lifter who wants the power rack, Smith machine and cables in one footprint. The pull-up bar and safety spotters are rated to 200 kg, J-hooks to 180 kg, and the Smith bar to 150 kg. Strong enough to grow with most lifters, from first squats to heavier training.
Yes. The 45 kg pin-loaded stack expands to 100 kg with additional plates, and there are 4 pegs for storing Olympic plates on the frame. It arrives loaded with attachments too: J-hooks, spotter arms, dip handles, a landmine, straight bar, lat pulldown bar and pulley handles. So most buyers won't need extras for a long while.

Download the user manual (PDF)Customers praised this 6-in-1 power rack as "excellent value for money" with smooth operation and functional design. The compact unit fits well in garage gyms. However, some reported cable durability issues, thin frame construction (1.6mm vs 3mm standard), and poor assembly instructions. A few received faulty/missing parts, though after-sales service resolved issues promptly.
Excellent value for money
Very happy with this
Quality product
Good system. Only issue I have is the cables. They aint designed for everyday use. My cables split and messed up in the first 6mths. The cables if snapped can cause major injury. Other than that is a very functional system. Definite end to purchase additional weights if your a heavy lifter as well.
The Cortex SM 20 is a definite must have for any garage gym. Easy to put together and great quality. It fits neatly into a small area yet boast the best workout ever. Worth every cent!!
Great piece of equiptment, smith machine is smooth and only took about a day to assemble. Only issues are the cables feel a little bit stiff when using, and i am unsure why the weight stack is in pounds, not kg. Other than that, good rack to have.
Bought this last week and just put it together after a few days. Could start building alone but eventually you need another person. Build quality is what you'd expect for the low price but I am satisfied with it. Unexpectedly, the delivered parts inside the box gave me 2 left side Smith safety racks so only one side has a safety bar attached to the frame. Also the attachment to put on the landmine came broken as you can see where the welding gave way for it to split. Quite disappointed to see that not one but two parts were wrong/ faulty despite being in the box and sealed on delivery. I will be calling to see what can be done for the faulty parts
We love our new power cage - we had excellent service and after service. It was quite easy to put together, although took about 5 hours by slow assemblers- my son is using it, not me!
I have had the Cortex SM-20 for 3 months now and I love it! Initially, I thought it was going to be a huge pain to put together. However, it was pretty easy with a second person. The Smith machine is smooth and works great for all sorts of workouts as well as the cables. The only thing on this machine I think that may not stand the test of time is the pull up bars as they are only held on with 2x 10mm bolts and have a very slight flex when doing pull ups. But overall the machine is fantastic ??
Pretty well made machine. Reasonably easy to put together if you have those sort of skills. Very Happy with the quality considering the low price.
Bought this for my wife and I. Its fantastic. Very good quality, easy to put together and hassle free purchase Definitely recommend
Literally replaces the gym! This is the best all in one gym set I've ever had. Takes a little while to set up, but is a great set. I can do any and all weight based exercises I could think of.
I purchased this rack a few weeks ago and I am very happy with it. The instructions were well written and had it together in a couple of days. The smith and cable machine will enable me to work out easily adjusting my weight from light to heavy as I progress. It does not require a spotter so I can lift weights safely by myself so I can train when I like and without going to a gym. It is a very heavy stable unit, I put it together myself, but if you are not experienced in assembling, I would recommend getting help to assemble the unit. I would also recommend the unit go into a garage and not into the house as it would have to be unassembled to remove from the house if it was required. Great weight training with this unit.
Feels and works like magic, the pictures don’t do it justice. Thanks team @Cardiooline :)
Bought this 3-4 weeks ago and wrote a previous review named "Monique". All issues have been resolved and the machine is not 100% functional. Overall, this product is a bang for your buck and works like a treat. Best part in my opinion is the design of the cable that attaches on the rack. It allows you to take it off and lock back on instead of conventional sliding design, which means it does not get stuck. Smith is super smooth and the cables run well and stay in the groove. I would buy this product again despite previous issues, the machine is just that great
I received this around 3-4 weeks ago and wrote a previous review. All issues have now been solved in a timely and stress-free manner with staff. The machine is now 100% built and functional. It is overall a fantastic machine for the low cost. As expected, the cables do twist when setting up but after straightening them out, they work well and stay on the grooves at all times. This is a really good all-in-one must have for a home gym. The cable height adjustment is more comfortable than conventional sliding ones, this one allows you to take it off completely and set it in. The smith runs super smooth and all attachments work well. I would buy again despite previous issues as the machine is awesome
Quick delivery, easy to setup. Have setup in the garage, looks tidy & is very functional
Bought this Machine a month ago but have only just gotten the ability to use it, Feel like the 100kg weight stack is a mis-direct, because of the mechanical advantage provided by the pulley system, if you only use 1 side of the rig at a time, you are only lifting 50% of the weight, so fully loaded at 100kg is only putting 50kg strain on each side of the rig
Not a bad unit for the price but as with most things the quality is what you would expect for this price point. The 16-gauge (1.6mm) thick frame is ~50% the thickness of most comparable units (3mm) and you can feel the difference during assembly and use. Be careful not to overtighten (which is tempting when plates do not mate up correctly) or you may buckle the square hollow section. Despite installing level and checking squareness for each piece prior to tightening, the smith machine guide bars are not square and therefore the bar does not return level on the rack. Whilst not a show stopper (but perhaps some feedback) the smith bar does not have the stop to prevent excess bar rotation when unracking like most machines, which could be improved with a simple welded tab. After driving ~1.5 hours each way to pickup, the boxes were missing a part to finish installing the cable system, which has since been shipped standard post (you'd think they'd offer express given the small part size and initial omission) so have not setup the cables yet. However, based on the showroom demo model the cable system is definitely not as smooth as other machines out there. In hindsight and after using with weights I would have rather paid double-triple for a better more durable unit (most come with lifetime frame warranty and 2 years on attachments) with better quality attachments, however for the price it will do the job for as long as it lasts.
Average rack the steel quality is not as solid as you expect but it will do the job for someone who doesn't want to pay too much. Set-up instructions are terrible and there is no marking done on the equipment for easy assembly.
Great machine for the price. Got pretty much everything u need. Instructions are very poor. Unless u good at building things like this I beleive u would struggle to build it. Wouldnt have hurt to put 4 more bolts in the kit and make it so u bolt down all 4 poles at the top and bottom not just the top. Would 100% make it feel even better. Little wider and taller wouldnt hurt either but for me does work just. Think again if ur tall. Would love a 4th and 5th weight racking bar and a second barbell holder. Nothing bad just my thoughts to better it.
This rack has everything you need. Very easy to setup and use. Absolutely love it
I bought the Cortex SM-20 package with the 100kg weight and bench package. I am beyond pleased with my purchase. The quality is great. All parts were there and everything was surprisingly easy to put together. Definitely recommend this product. Great value compared to similar stations.
Great machine, very easy to assemble. Works really well. I would not hesitate to buy another one
