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. The front section of the trainer doubles as a half rack, equipped with upgraded J-Hooks and Spotter Arms for safe, confident barbell training.
Tailor your resistance training with the C20’s dual 200 lb (90.7 kg) weight stacks — easily upgradeable to 250lbs (113kg) or 300 lbs (136 kg) per stack with our optional Weight Stack Upgrade. Each stack also includes a built-in 5 lb (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.
The C20 features six-pulley stations. Our uniquely designed Freestyle Pulleys allow you to increase the height of the pulleys to 190cm (highest point) & … (lowest point). They can swing freely from left to right and can be locked in place, providing 180 degrees of versatility. Dual low pulleys sit at the base, perfect for seated rows or connecting with our patent-pending Sliding Bench. A dedicated double high pulley station targeted for upper-body exercises can be connected via the Dual Pulley Connector to double the intensity.
Level up your C20 with our exclusive patent-pending Sliding Bench that replaces five machines in one compact design, from presses and squats to curls and extensions. It’s your all-in-one leg-day game-changer, cable-connected straight from the lower centre pulleys to the stacks. No extra plates required!
Say goodbye to gym clutter. The Force USA C20 includes a pegboard system (with pegboard pins included), built-in shelf storage, barbell (x1) and plate holders (x8), and additional pegboard mounts on the shrouds, giving you five smart storage options in total.
Add functional bodyweight training into your split with the integrated multi-grip pull-up bar and brand-new spotter arm dip station. Both are knurled for a solid grip and built into the frame for maximum stability. Plus, a fixed TRX hook opens up even more options with suspension training, rings, or bands, perfect for core, mobility, and rehab work.
This machine comes with aluminium pulleys for a smoother, longer-lasting performance rep after rep. Included attachments like an EZ Curl Bar, Lat Pulldown Bar, Tricep Rope, Triangle Row Handle, Ankle Cuffs, and more ensure you’re ready for any workout. Plus, the magnetised landmine attachment stores easily, adding yet another dynamic training element to your arsenal.

Yep. The C20 is an open-source training system with 3x3 uprights, 1-inch holes, and 2-inch spacing — the industry standard for serious gear. That means it plays nice with a wide range of third-party attachments, giving you the freedom to build, customize, and expand your setup exactly how you want. It's next-level versatility in an All-In-One.
The C20 is the 3x3 evolution of the C10. Same core functionality, but built to flex harder. It’s beefier, more customizable, 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 Aluminum attachments. This isn’t a makeover—it’s a full-blown transformation.
The base bench includes a Leg Curl, Leg Extension, and Preacher Curl station. If you're planning to go hard on leg day, the Sliding bench is a better pick. It adds a Leg Press and Hack Squat station, offering more lower-body options that connect to the dual integrated stacks.
You’ll need a ceiling height of at least 97 inches to do a full pull-up with your head clearing the bar. Any lower, and you’ll be cutting your range short.
Anticipate 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 set of hands and a ratchet set will make things faster and smoother.
The C20 comes with dual integrated 200 lb weight stacks for the Functional Trainer and includes the 35 lb 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.
The C20 is designed to work with standard Olympic plates.
The C20 features a 2:1 ratio on the Functional Trainer—load 100 lb, get 50 lb of resistance. On the Lat Pulldown and Low Row, you’re in control: connect both upper pulleys for a 1:1 ratio (pulling from both 200 lb stacks), or go 2:1 with a single pulley for 100 lb resistance. Same goes for the lower pulleys—run one side for a 1:1 ratio at 200 lb max, or both for a 1:2 setup that delivers up to 400 lb with the base stacks—or 600 lb fully upgraded.
Yep, the dual 200 lb integrated stacks can each be upgraded with optional 50 lb add-ons to each side, bringing the total weight to either 250 lb or 300 lb.
The total shipping weight for the C20, including crates and packing material, is around 1,300 lb. It ships in two large wooden crates via LTL freight delivery.
You will not regret buying this one bit, except maybe while building 🤣 but that pain will be short lived and a thing of the past once you finish and see that this is a thing of beauty. Goodbye to my gym membership and the commutes back and forth. This does everything you could ever need. I’ll just be living out in my gym shed now, patiently waiting for the sliding bench 💪
