The Force USA® Jammer Arms turn your All-In-One Trainer into a power-building machine that hits harder than anything you’ve tried before. Engineered to fit 2" × 2" uprights on every G and C-Series, these attachments deliver the kind of chest, shoulder, arm, and back work that takes your training up a level.
Compact and efficient by design, they’re the opposite of the bulky, awkward Jammer Arms you’ll find elsewhere. Quick to attach and effortless to adjust, they flow with your session instead of slowing it down—so you can stay locked in and keep lifting heavy.
With multiple grip positions and a durable black powder-coated finish, Jammer Arms are built for endless presses, pulls, and power moves. Smooth, strong, and designed by engineers who train, they’re the upper-body upgrade your gym has been waiting for.
The Force USA® Jammer Arms add serious variety to your workouts—unlocking bench press, incline press, shoulder press, deadlifts, rows, and more, all from your All-In-One Trainer. Whether you’re chasing size, strength, or explosive power, these arms expand your options without taking up extra space.
Multiple grip positions let you dial in the feel for every movement, while the quick attach-and-detach design keeps your training flow seamless. Built from commercial-grade steel and finished with a high-grade black powder coat, they’re engineered to take whatever you throw at them, session after session.
From isolating upper-body muscle groups to driving full-body compound lifts, Jammer Arms bring a new edge to your All-In-One. Compact, durable, and versatile, they’re the upgrade that makes every rep count.
