With a solid cast iron core, the China Special Quality 5 kg PU Dumbbell provides high-density resistance for strength training. Polyurethane encasement prevents floor damage while dampening impact noise during heavy drops. The aluminum knurled handle maintains a secure grip during high-repetition sets.
Key Features
