3" Cable Grenade Ball

The 3” Cable Grenade Ball is a compact metal-sphere cable attachment from EliteFTS built to train pinch-grip strength rather than the crush grip most grip tools target. It connects to any cable stack (or a pull-up bar, with a strap and carabiner) and is used for lat pulldowns, cable rows, curls, tricep extensions, flies, and cable crossovers – forcing the hand to grip a smooth sphere instead of a handle, which EliteFTS and reviewers say increases forearm and grip demand on otherwise-familiar exercises.

Legion Athletics names it “Best Ball Grip Strengthener” in its grip-trainer roundup, praising the unique pinch-grip stimulus and adaptability across cable and pull-up-bar work, while noting it needs extra hardware (strap, carabiner) to use on a bar. EliteFTS markets it with a testimonial from IFBB pro Amit Sapir and claims it reduces elbow strain on tricep extensions and increases pec activation on flies, though those specific claims aren’t independently verified. Material and build-quality detail are thin across every source – it’s documented only as a 3-inch metal sphere – and no independent long-term durability testing surfaced.
