The Medicine Ball Rubber 4kg is a solid mid-range training weight for athletes who want to develop explosive power, rotational strength, and full-body conditioning. The tough rubber construction is built to absorb the impact of slams and throws session after session, while the textured surface provides a secure grip even during intense workouts. Suitable for CrossFit, team sport conditioning, and general gym training, the 4kg ball strikes the right balance between challenge and control for most adult athletes.
