Force USA C20 CORNERSTONE® All-In-One Trainer: 3x3 Power Rack, Smith Machine & Functional Trainer
Force USA built the original All-In-One Trainer, then created the first one with a center cable system. The C20 is the world's first center cable design built on 3x3 uprights, 11-gauge steel, 1" holes, and upgradeable weight stacks — the most advanced All-In-One Force USA has ever created.
In one footprint you get a true 3x3 half rack, a Single Track Smith machine, dual Freestyle Pulley Arms, high and low center cable stations for lat pulldowns and low rows, a pull-up station, dip handles, a magnetic landmine, and built-in storage. Weight stacks scale from 200 to 300 lb per side, and 22 pro-grade attachments are included so you can train on day one.
Add the patent-pending Sliding Bench (sold separately) and the C20 also becomes a leg press, hack squat, leg curl, leg extension, and preacher curl station — all cable-connected to the dual weight stacks, with up to 600 lb of resistance and no plates required.
1" holes spaced every 2" give open compatibility with third-party 3x3 attachments. 49" exterior / 43" interior rack width.
The frame keeps continuous floor contact and self-adjusts to slightly uneven floors — no pedestal-foot wobble.
Lock Mode fixes the arms for heavy hypertrophy work; Flow Mode lets them track your movement for functional, explosive, and rotational training.
Dual Freestyle Pulley Arms plus high and low center cable stations — train every angle without reconfiguring the machine.
Guide rod, linear bearings, and safety lock in one column wrapped in 5-gauge steel. Low starting position allows a full deadlift range of motion. 35 lb bar with spinning sleeves.
Upgradeable to 250 lb or 300 lb per side. Built-in 5 lb micro-adjustment plate for smaller jumps. Up to 600 lb of cable resistance with both 300 lb stacks connected.
Black anodized aluminum cable handles, Quick-Lock J-cups and spotter arms, and UHMW inserts that protect your barbell's knurling.
47-slot pegboard with 12 pegs, recessed accessory shelf, 8 Olympic plate horns, UHMW-lined barbell holder, and a magnetic landmine that parks flush.

See the C20's standout features in action — from the patent-pending Sliding Bench to the Freestyle Pulley Arms and beyond.
Sliding Bench Integration
The patent-pending Sliding Bench (sold separately) combines leg press, hack squat, leg curl, leg extension, and preacher curl. Connected to the lower center cables, it delivers up to 600 lb of resistance and stores upright against the wall when not in use.
True 3" x 3" 11-Gauge Uprights
Built to the professional standard with 3" x 3" 11-gauge steel uprights and 1" holes spaced every 2", compatible with the broader ecosystem of 3x3 equipment and attachments.
Freestyle Pulley Arms
Lock Mode holds each arm in a fixed position for rows, presses, and pulldowns. Flow Mode frees the arms to follow your body through 180 degrees of motion for athletic and rotational work.
Six Pulley Connections
Two Freestyle Pulley Arms plus high and low center cable stations, with three pulley ratios to match every movement, load, and training style.
Single Track Smith Machine
Train heavy, train safe. The guide rod, linear bearings, and safety lock sit in a single 5-gauge steel column, and the low starting position enables a full deadlift range of motion. The 35 lb bar has professional-standard knurling and spinning sleeves.
Dual 200 lb Weight Stacks, Upgradeable to 300 lb
Start with dual 200 lb stacks and upgrade to 250 lb or 300 lb per side. With both 300 lb stacks connected, the center cables deliver up to 600 lb of resistance.

Frequently Asked Questions
Q: What's the difference between the Force USA C10 and C20?
The C20 is the 3x3 evolution of the C10. It keeps the center cable functionality but adds a heavier 3x3 frame, upgradeable weight stacks, aluminum attachments as standard, and pegboard and shelf storage the C10 doesn't have.
Q: What are the dimensions of the C20?
The C20 measures 77" W x 66" D x 88" H. With the Sliding Bench attached, the depth extends to 128". Leave extra room around the frame for the pulley arms, plate loading, and barbell movement.
Q: What ceiling height do I need?
At least 97" for a full pull-up with your head clearing the bar. The machine itself is 88" tall.
Q: How heavy is the C20?
About 1,290 lb assembled. It ships at roughly 1,300 lb in two wooden crates via LTL freight.
Q: What is the weight stack capacity?
The C20 ships with dual 200 lb stacks. Each can be upgraded with a 50 lb add-on to 250 lb or 300 lb. Connecting both bottom center pulleys gives up to 400 lb of resistance with the standard stacks, or 600 lb fully upgraded.
Q: How do the pulley ratios work?
Freestyle Pulley Arms run 2:1, Top Center single pulley is 2:1, Top Center dual pulley is 1:1, Bottom Center single is 1:1, and Bottom Center dual is 1:2 — effective resistance from 50% to 200% of the loaded weight.
Q: What attachments are included?
22 attachments, including aluminum lat, short, and EZ curl bars, single handles, tricep rope, Quick-Lock J-cups and spotter arms, dip handles, a magnetic landmine, ankle cuffs, plate holders, pegboard pins, collars, and floor-bolting brackets. See the full list above.
Q: Are a bench, barbell, or plates included?
No. The C20 includes the dual 200 lb stacks and the 35 lb Smith bar. A bench, barbell, and Olympic plates are sold separately.
Q: Does the C20 work with attachments from other brands?
Yes. With 3x3 uprights, 1" holes, and 2" spacing, it's compatible with a wide range of third-party 3x3 attachments.
Q: Should I choose the Base Bench or the Sliding Bench?
The Base Bench includes leg curl, leg extension, and preacher curl. The Sliding Bench adds leg press and hack squat, so it's the better pick if lower-body training is a priority.
Q: How long does assembly take?
Around 5 hours or less. Tools, hardware, and instructions are included; a second person and a ratchet set make it faster. Delivery and setup options are available from Fitness Supply.
Q: Is the C20 rated for commercial use?
Yes. Force USA lists the C20 as a Commercial Grade product. Commercial use carries a Limited Lifetime frame warranty, 5 years on moving parts, and 6 months on upholstery and attachments. Home use carries a Lifetime frame warranty, 10 years on moving parts, and 1 year on upholstery and attachments.
