Force USA® was the pioneer behind the original All-In-One Trainer. Then it developed the first model with a center cable system. Now, it’s changing the game once again with the Force USA C20 — a true CORNERSTONE®, built to be the foundation of your entire gym. It’s the world’s first center cable design featuring 75 × 75 x 3 mm uprights, 25 mm holes, and upgradable weight stacks. Overbuilt? That’s the whole point. No compromises here.

Force USA took the concept even further. Its Freestyle pulley arms move up, down, in, and out, gliding smoothly along upright trolleys with a 2:1 ratio. Dual 90.7 kg weight stacks — upgradeable up to 136 kg — power the center cable system, combined with upper pulleys (1:1 / 2:1 ratios) and lower pulleys (1:2 / 1:1 ratios) for true 90° lat pulldowns and low rows. Polished aluminum pulleys run throughout, delivering smooth motion and a bold, premium look.

Then comes the real game-changer: Force USA’s patent-pending Sliding Bench option, which locks into the lower pulleys to unleash up to 272 kg of cable-driven resistance for leg presses, hack squats, and more. The C20 is engineered with a space-saving footprint that doesn’t just fit your space — it transforms it. This is the C20, built by lifters, for lifters.

MEET THE WORLD'S FIRST CABLE-CONNECTED SLIDING BENCH

COMMERCIAL-GRADE SMITH MACHINE + HALF RACK COMBO

Whether you’re locking in heavy barbell squats or dialling in form on bench press, the C20’s commercial-grade Smith Machine brings that real gym feel home. Built to IPF and IWF standards with medium knurling and smooth travel, it’s perfect for controlled lifts. It also integrates a rack with J-Hooks and safety spotter arms, so you can train with total confidence, as part of the CORNERSTONE® system built to bring all your training into one machine.

CUSTOMISABLE WEIGHT STACKS WITH MICRO ADJUSTMENTS

Tailor your resistance training with the C20’s dual 90.7 kg weight stacks — easily upgradeable to 113kg or 136 kg per stack with the optional Weight Stack Upgrade. Each stack also includes a built-in 2.26 kg fractional plate, letting you progress with precision. Whether you’re pushing max strength or dialling in accessory work, this system keeps your programming sharp and adaptable.

SIX-PULLEY SYSTEM FOR ULTIMATE VERSATILITY

The C20 features six pulley stations. The uniquely designed Freestyle Pulleys can be raised up to 190 cm at their highest point and swing freely from left to right. They can also be locked in place, offering 180 degrees of versatility. Dual low pulleys at the base are perfect for seated rows or connecting with the patent-pending Sliding Bench. A dedicated double high pulley station, ideal for upper-body exercises, can be linked via the Dual Pulley Connector to double the intensity.

FAQS

What's the difference between the C10 and the C20?

The C20 is the 75 x 75 mm (3x3") evolution of the C10. Same core functionality, but built to perform harder. It's beefier, more customisable, with features like pegboard and shelf storage you won't find on the C10. The dual weight stacks are upgradeable and come standard with premium aluminium attachments. This isn't a makeover — it's a full transformation.

Does this play nice with attachments from other companies?

Yes. The C20 uses 75 × 75 mm uprights, 25 mm (1") holes, and 50 mm (2") spacing — a common standard for serious equipment. That means it works with a wide range of third-party attachments, giving you the freedom to build, customise, and expand your setup exactly how you want.

Which Cable-connected bench option should I choose?

The Base Bench includes a Leg Curl, Leg Extension, and Preacher Curl station. If you're planning to train hard on leg day, the Sliding Bench is the better pick — it adds a Leg Press and Hack Squat station, offering more lower-body options connected to the dual integrated stacks.

What's the minimum ceiling height I need?

You'll need a ceiling height of at least 246 cm to do a full pull-up with your head clearing the bar. Any lower and you'll be limiting your range of motion.

How long does it take to assemble a C20?

Expect assembly to take around 5 hours or less. Everything you need — tools, hardware, and instructions — is included. You can do it solo, but a second pair of hands and a ratchet set will make things faster and smoother.

Are weight plates, a bench, or a barbell included?

The C20 comes with dual integrated 90 kg weight stacks for the Functional Trainer and includes the 16 kg integrated Smith Machine bar. A bench, barbell, and plates are not included — they're available separately so you can build out your setup your way.

What size weight plates are compatible with the C20?

The C20 is designed to work with standard Olympic plates (50 mm).

What is the cable pulley ratio?

The C20 features a 2:1 ratio on the Functional Trainer — load 45 kg, get 22.5 kg of resistance. On the Lat Pulldown and Low Row, you're in control: connect both upper pulleys for a 1:1 ratio, or use a single pulley at 2:1 for 45 kg of resistance.

Can the weight stacks be upgraded?

Yes, the dual 90 kg integrated stacks can each be upgraded with optional 22.5 kg add-ons to each side, bringing the total weight to either 113 kg or 135 kg.

What is the shipping weight?

The total shipping weight for the C20, including crates and packing material, is around 590 kg. It ships in two large wooden crates via palletised freight delivery.
