The Hammer Strength Ground Base Jammer (GB-J) is engineered for athletes who demand ground-based power, explosiveness, and total-body strength development. Ground Base training keeps the athlete’s feet planted firmly on the floor, replicating real-world athletic movements and transferring force efficiently from the lower body through the upper body.
