These fully articulating arms move across three planes of motion with multiple locking points, giving you the freedom to replicate nearly any leverage-style exercise you’d find in a commercial gym. From chest presses and rows to explosive athletic movements, the 3D Jammer Arms let you add variety and intensity like never before.

What makes this upgrade truly unique is its dual leg press functionality. The included plate allows you to perform a vertical leg press using the Smith bar for maximum load capacity, as well as a seated leg press with the jammer arms for a joint-friendly variation that operates off the weight stacks. That means you’re not limited to just upper-body leverage exercises—you can also train your lower body with the same add-on, making it one of the most versatile accessories available for any all-in-one gym.

As a bonus, the 3D Jammer Arms are also compatible with most other leading 2″x2" and 3"x3″ rack systems with 1" Holes, so even if you expand your gym in the future, this investment carries over. For athletes who want limitless options and the ability to replicate their favorite machine-based movements at home, this upgrade is a game-changer.
