Best 100kg Multi Gyms
If you are already strong or expect to progress a lot, a 100kg weight stack is what keeps a multi gym challenging for years rather than months. Here are the best 100kg multi gyms in the UK, ranked on FitRank, compared on build, stations and price, with an honest pick for every budget.
A 100kg stack is the most resistance you will find on a home multi gym, and it is the right choice for anyone who is already reasonably strong, since the weight adds up fast on pressing and pulldown movements and a smaller stack is quickly outgrown. It is also the one specification you cannot upgrade later, so if you expect to keep progressing, buying into the full 100kg now is the sensible call.
The trade-off is that a 100kg stack needs a taller, heavier and more expensive frame, so these are the largest and most substantial machines we cover, and they need the space and the assembly time to match. We have compared the 100kg machines worth buying in the UK and ranked them on FitRank, our editorial score out of 5 that weighs performance, build, value and features against each machine’s price and rivals.

adidas Performance Home Gym
The adidas Performance is the best 100kg multi gym, a heavy, solid machine that puts the full 100kg stack to work across three load points, so you can target every major muscle group without swapping mechanisms. The station list is long, bench press, butterfly, pec dec, chest press, lat pulldown, low row, arm curl, leg extension, back leg curl and preacher curl, and it ships with handle, ankle, z-bar and short-bar attachments.
At 176kg it is one of the most planted machines you can buy at home, which matters when you are pressing near the top of a 100kg stack, and the powder-coated steel and dense foam feel a class above budget rivals. A two-year warranty and a ‘Scan to Train’ video library round it out. Down from £1,000 to £699, it is the one to beat.
Best for Anyone who wants the most solid, complete 100kg machine and a trusted brand behind it.
Watch-out It is big and very heavy, so plan the space and the assembly. Maximum user weight is 125kg.
York Perform Multi Gym
The York Perform matches the adidas on stack size for less against its rivals, and brings York’s pedigree with it. A 4.7-star rating across 42 reviews backs a machine built on sealed bearings for a smooth, snag-free pull, with separate press and pec arms so you move between chest press and pec deck without changing anything or leaving the seat. Stations cover chest press, pec deck, leg extension, arm curl, low row and lat pulldown.
The translucent stack shroud and Y-frame add safety and stability, and there is a two-year warranty. At £699, down from £799, it is the value route to a full 100kg from an established British brand.
Best for Buyers who want a full 100kg stack and smooth, seated station changes for less outlay.
Watch-out Assembly runs to several hours, and taller users note the narrow footprint can affect stability.
Strongway Multi Gym with Weights
The Strongway is the budget way to a 100kg stack, sold in a 100kg version alongside the cheaper 72kg model. A sturdy steel frame carries a dual-action chest station with chest press and pec deck, high and low pulleys, an adjustable preacher pad and a one-piece butterfly press, with micro cable adjustment and a double pulley system, and it holds a 4.5-star Amazon rating.
Owners are candid that the build is a challenge and takes time, and it is a large machine at 186 by 108cm. But if you want the full 100kg for the lowest outlay and do not mind a long assembly, the 100kg version delivers the resistance.
Best for Strength trainers who want a 100kg stack at the lowest price and will tolerate a tough build.
Watch-out A long, fiddly assembly by owner accounts, and Amazon-based support rather than a specialist retailer’s.

Is a 100kg stack right for you?
A 100kg stack suits people who are already training with some resistance behind them, or who expect to build strength steadily and do not want to hit the ceiling of a smaller machine within a year. On a multi gym the stack is shared across stations through the pulley ratios, so the effective resistance varies by exercise, but on the big pressing and pulldown movements you will genuinely use the top of a 100kg stack sooner than you might think.
If you are starting from scratch and training mainly for general fitness and tone, you may not need the full 100kg, and a 70 to 80kg machine will save you money and space. Our best home multi gyms guide covers those, and the compact options if room is tight. But you cannot add weight to a stack later, so if in doubt, size up.
What 100kg costs you in space and setup
The bigger the stack, the bigger the machine. These 100kg gyms stand around 205 to 214cm tall and need roughly 1.5 to 2 metres in each direction once you allow for the moving arms, so measure your space and your ceiling before ordering, particularly in a garage. The adidas at 176kg and the York at 162kg are heavy, which is good for stability but means a two-person build.
Assembly is a real commitment on machines this size, running to several hours, and owners of both the York and the Strongway single out the cable routing as the fiddly part. It is a one-off job, but set aside an afternoon, keep the manual close, and where you can, build with a second pair of hands.
How we chose these machines
Every machine here is scored on FitRank, our editorial rating out of 5 that weighs performance, build, value and features against each machine’s price and rivals. We do not rank by commission, and the order follows the scores. Our assessments draw on published specifications, build details, stations and independent owner feedback rather than a single showroom session.
