Force USA’s G12 model is the global best-seller and original All-In-One trainer. A complete training solution that ticks all the boxes and hits all fundamental training movements to build strength, power, muscle mass and stamina. Your G12™ All-In-One Trainer lets you perform:
The Force USA® G12™ All-In-One Trainer is equipped with 2x 100kg (220lb) weight stacks (1:1 ratio) located at the back of your unit for complete resistance control on over 75 unique exercises.
Backed by some serious R&D, Force USA has delivered a weightless (counterbalanced) Smith Bar with the smoothest movement on the market. This allows entry-level users to learn the correct movement of any exercise before they start loading on weight.
The G12’s™ Smith Bar also includes state-of-the-art knurling for an unrivalled feel during heavy squat and deadlift sessions while easily converting into an awesome leg press machine.
Your ergonomically designed multi-grip chin-up and pull-up station has a huge 450kg weight rating. With an ultra-comfortable knurled grip, you can perform wide-grip, close-grip, underhand, overhand and many other positions to build strength and muscle mass.
You can also hook up your resistance bands to the conveniently placed anchor point to perform your favourite explosive exercises.
The G12 introduces a new era of compatibility. With universal 2" x 2" uprights featuring 17mm hole sizing, this design standard guarantees that both existing and future attachments will seamlessly integrate with your machine, offering unparalleled versatility.
Don’t settle for anything less - your G12™ All-In-One Trainer was precision-built and manufactured using commercial-grade materials. With a Lifetime Warranty and 2-year warranty on parts and attachments, the trainer includes:
The G12™ has been engineered to handle the heaviest loads while protecting your barbell with Commercial grade J-Hooks and Safety Spotting Arms with safety locking. Every J-Hook and Safety Spotting arm is covered with a removable nylon barbell protector sleeve to protect your barbell knurling and extend the life of your barbell.
Train confidently, knowing every safety mechanism has been carefully designed in the G12™. This includes smart safe lock and release mechanics, and high-quality safety catches, so you’ll never need a spotter on those big squat and bench days.
The quality of the sliders on your G12™ All-In-One Trainer are second-to-none, delivering a smooth, reliable and satisfying experience when moving between exercises and positions.
Change up your workout routine with the low row footplate for your G12™. The angled footplate allows for optimum foot positioning and stability during exercises, while the textured tear pattern finish ensures feet are secure, minimising the risk of slipping.
With internal rack dimensions of 101.6cm (W) x 115.57cm (D) x 208.28cm (H), the G12™ All-In-One Trainer is ingeniously designed to offer a spacious workout experience within its compact footprint.

Assembly of the G12 takes approximately 6 hours. All tools and hardware are included in the box. While it is possible to assemble it alone, having help and using ratchets will make the process more efficient.
This unit accepts and stores Olympic plates for the base Functional Trainer and Smith Bar.
The functional training cable is a 6.2 mm nylon coated mil-spec aircraft quality cable tested to 2,000 lb.
The G12 features a 1:1 cable ratio. The 1:1 ratio means that if you have 100 lb loaded, the resistance is 100 lb.
While it comes with stack weights for the functional trainer, you must purchase plate weights for the Smith Machine and Half Rack separately. Additional weights, benches, and barbells are available individually in our online store.
The minimum ceiling height to do a full pull-up with your head above the bar is 7 ft 8 in.
After a couple weeks of ownership and regular training, I can confidently say the Force USA G12 has exceeded my expectations.
The unit arrived in a large wooden crate and was packaged exceptionally well. Every component was protected with bubble wrap and arrived in excellent condition. From the moment we unpacked it, it was obvious that a lot of thought had gone into both the product design and the presentation.
The build quality is outstanding. The G12 feels incredibly solid, stable and well engineered. I had some concerns before purchasing that an all-in-one machine with so many functions might feel compromised or flimsy in certain areas, but that has not been my experience at all. The pulleys are smooth, the powder coating is high quality, the attachments are well finished, and the entire unit feels premium.
What impressed me most is just how much functionality is packed into a single machine. Combined with a bench, dumbbells, a barbell and plates, the G12 is essentially a complete gym. Whether your goal is strength, hypertrophy, conditioning or general fitness, there is very little you cannot do with this setup.
Assembly was straightforward but time consuming, it took me roughly 16 hours to complete with the hlep of my Dad. Force USA includes all the tools required to build the machine, which is appreciated, but I would strongly recommend having an impact wrench available. It made assembly significantly faster and easier.
My only real criticism is the instruction manual.
To be completely honest, the instructions are the weakest part of the entire package. The machine itself feels premium, but the instructions feel far behind the quality of the product. They can be confusing at times and are nowhere near as intuitive as something like IKEA's manuals.
My advice to anyone building a G12 is to use both the manual and YouTube build videos together. Doing that made the process much easier.
One additional tip I wish had been included in the instructions relates to the pulley cables. Before installation, take the time to fully uncoil and straighten the cables. They arrive tightly wound and taped for shipping. If you rush this step and accidentally introduce twists into the cable during installation, you may find some of the floating pulleys do not align perfectly. Laying the cables out first and carefully feeding them through the machine saves a lot of potential troubleshooting later.
Another tip I have is regarding threading the cables through, on the side that attachments connect on to for the pulley cables, you can actually easily remove the black stopper ball, this allows for easier threading of the pulley cable, which again is not mentioned in the instructions.
Overall, the G12 is one of those purchases where you can immediately see where your money went. The engineering, finish quality and versatility are excellent. It has become the centrepiece of my home gym and has allowed me to create a training setup that rivals many commercial gyms.
Highly recommended.
I recently picked up the Force USA G12 and couldn’t be happier with the decision. After a lot of research and comparing different all-in-one trainers, the G12 stood out for its versatility and build quality. Having a single machine that combines a power rack, functional trainer, Smith machine, and multiple cable options has been a huge upgrade for my home gym. It feels incredibly solid and well-engineered, and the range of exercises it supports means I rarely feel like I’m missing anything from a commercial gym.
I installed the unit myself and the process was surprisingly simple and straightforward. The instructions included in the box were clear, and there are also some helpful YouTube videos that walk through the setup step-by-step. Between the two, the assembly was very manageable even doing it solo.
The packaging was also excellent. Everything arrived extremely well protected and organised, which made unpacking and assembling the machine much easier. It’s clear a lot of care went into making sure all parts arrived safely.
A big shout-out to Gym and Fitness as well — their support throughout the process was amazing. They were incredibly helpful answering questions, providing advice, and making sure I chose the right setup for my space and goals. The whole experience, from research to purchase and setup, was smooth and professional.
If you’re looking for a premium all-in-one home gym solution, the Force USA G12 is definitely worth considering.
