Best multi gyms for home UK (2026)

Measure your ceiling and floor before anything else. The rack-style all-in-one trainers in this guide stand 220 to 221 cm tall and need about 2.5 m of ceiling for a full pull-up, while the rack-free machines with published heights stand 183 to 212 cm. If you have the height, an all-in-one trainer with a rack, Smith machine and cable stacks replaces most of a commercial gym; if you don't, a functional trainer or a lower multi gym is the answer.

In the UK, the Force USA G3 V2 (plate-loaded) and G4 (two 77 kg stacks) are the all-in-one multi gyms to beat, and the Mirafit M4 Functional Trainer is the pick if you want cables without a rack.

How to choose a home gym machine

Ceiling height comes first

Take the machine's listed height and add room above it. You need space to tilt the uprights up during assembly, and for pull-ups you need room for your head above the bar. Force USA puts the minimum ceiling for a full pull-up on the G3 and G4 at 254 cm, against a machine height of about 220 cm. Basements, garages and lofts are often lower than living rooms, so measure the actual room.

Footprint and working space

The listed footprint is the frame. Cable work needs more: you step forward for presses and back for rows, and arms swing wide on flyes. BowFlex is unusually clear about this, listing a 134.6 x 124.5 cm frame but a 284.5 x 381 cm workout area for the Xtreme 2 SE. For rack-style trainers allow room behind for loading plates and in front for a bench.

Multi gym, functional trainer or all-in-one

• Multi gym (single-station): one weight stack driving a fixed press, pulldown, row and leg station. Compact and simple, but the movements follow set paths.
• Functional trainer: two independent cable columns with adjustable pulley heights. Free movement in any direction, ideal for cable flyes, rows, face pulls and rotational work. No barbell work.
• All-in-one trainer: a power rack, Smith machine and functional trainer in one frame. The most versatile, but also the tallest and heaviest, and the plate-loaded versions need plates you buy separately.

Weight stack and cable ratio

A 2:1 cable ratio halves the resistance you feel: Force USA's example is that 100 lb loaded feels like 50 lb. That gives smoother, faster cable movement and longer travel, but a 77 kg stack at 2:1 feels like about 38 kg per handle. If you want heavy cable rows or pulldowns, check whether the machine lets you join both stacks or switch to a 1:1 attachment. BowFlex rods and SpiraFlex plates are rated in pounds of resistance rather than stack weight, and rod resistance changes through the range.

Delivery and assembly

These machines arrive on a pallet. The G3 V2 weighs 184 kg and the US G3 202 kg before plates, and Force USA quotes 2 to 4 hours of assembly for its G-series trainers. Check the delivery is to your room, not the kerb, and that the boxes fit your doors and stairs.

Force USA G3 V2 All-In-One Trainer

The G3 V2 is the updated G3 that Force USA sells in the UK. It keeps the power rack, Smith machine, plate-loaded 2:1 functional trainer and pull-up bar, and adds linear bearings on the Smith bar, uniform 1 in hole spacing, a slightly lower pull-up bar for more head clearance, longer 20 cm weight pegs and a frame 10 cm deeper. Force USA lists it at 192 x 154 x 220 cm with a 102 x 125 x 200 cm interior, a 184 kg product weight, a 450 kg weight rating and a 350 kg chin-up bar rating. The minimum ceiling for a full pull-up is 254 cm, and the base has holes for bolting it to the floor.

Force USA G4 All-In-One Trainer

The G4 keeps the rack, Smith machine, landmine and pull-up bar, but the cables run on two 170 lb (77 kg) weight stacks, 154 kg in total, at 2:1. Each stack can be upgraded to 220 lb (100 kg). It measures 75.6 x 60.6 x 86.6 in (192 x 154 x 220 cm). Force USA rates the frame to 992 lb (450 kg) and the chin-up bar to 771 lb (350 kg), and gives the same 254 cm minimum ceiling for full pull-ups as the G3.

Mirafit M4 Functional Trainer

The M4 is a commercial-grade freestanding functional trainer with two 100 kg weight stacks, each with 20 settings in 5 kg steps, at a 2:1 pulley ratio. The side pulleys have 20 height positions at 80 mm spacing, and there is a multi-grip pull-up bar on top. It is 212 cm tall, 208 cm wide and 102 cm deep, and Mirafit recommends allowing at least 15 cm of extra ceiling height for installation. It weighs 325 kg, arrives kerbside in a crate and needs at least two people to assemble.

How we chose

We have not tested these machines. We compared current models on the specs their makers publish, with ceiling height and footprint first because they decide whether a machine fits at all, then resistance, cable ratio, load ratings and warranty. We checked each one is sold new in each market by the maker's own country site or a retailer shipping from inside that country. Where a maker does not state a figure, we leave it blank.
