Hammer Strength Ground Jammer *REFURBISHED*

The Hammer Strength Ground Jammer anchors one end of a barbell to a rotating base, letting athletes perform landmine-style presses, rotations, and single-arm movements that build core and full-body strength in ways a standard barbell setup can't. It's built for the same heavy training volume Hammer Strength engineers its athletic equipment around. Our technicians inspected the base and hardware and refurbished this unit before resale.
