The C20 isn’t just another All-In-One—it’s a CORNERSTONE® Trainer, the foundation you build your entire gym around. If it’s not from Force USA®, it’s not a CORNERSTONE®. It takes everything you love about our original All-In-One Trainers—and dares to do more.
It starts with a 3×3 Power Rack. The advantage is everything layered on top from a Functional Trainer, dedicated 90-degree Lat Pulldown and Low Row, Smith Machine, Chin-up, Suspension Trainer, Landmine, and more. Strength, versatility, and variety combined into one serious strength system.
It takes everything you expect from an All-In-One and turns the dial up to 11. Every inch was rethought, rebuilt, and intentionally designed to handle serious weight—and makes no apologies for it. Our engineers didn’t just tweak the C10 design—they tore it down and reimagined it from the ground up to create something entirely new.
Proof of that mindset shows up in the details. Matte black electrostatic finish, clean lines, and crisp knurled touchpoints where it counts. Polished aluminum pulleys bring bold style and smooth performance, while laser-cut numbers inside and out keep your adjustments quick and precise. Quick-lock, UHMW-lined J-cups protect your bar, and the Smith bar comes dialed with IPF/IWF marks, crisp knurling, and buttery-smooth travel.
The same attention carries through to attachments. How about an open ecosystem, so you can use Force USA attachments or add third-party options—so you’re never boxed in? Yep, it’s got it. Reversible cable trolley handles face in or out, premium black anodized aluminum attachments stay grippy and light, and quick-lock 19” spotter arms turn inward, converting into dip handles with 1” knurled grips.
And it doesn’t stop there. The adjustable chin-up bar handles dial in your perfect grip, while magnetic band pegs snap in quick to level up the resistance. The adjustable 11-gauge diamond-plated footplate works on a bench or the ground, so you can switch up your training without missing a beat.
Storage brings it all together with a 47-slot pegboard, 12 pegs, 8 plate sleeves, and a recessed shelf to keep gear tight and floors clear. One-inch holes across the entire frame let you rack storage anywhere. The Smith bar stores at 6’4” clearance, so you won’t crack your head. As you can see, nothing feels like an afterthought here—because nothing was.
