This rubber hexagonal dumbbell is extremely cost efficient with a self evident function. The handles are ergonomic and steel bending. They are completely welded and precisely connected to the head with maximum strength. This avoids damage and any need for secondary maintenance. The head is wrapped in a rubber layer with a thickness of 12mm that gives the dumbbells shock absorption and buffering capacity. This effectively protects the floor and other surrounding equipment. The handle is processed with medium strength knurling that improves grip and comfort. The surface of the handle is beautifully electroplated, and extends the life of the dumbbells by preventing rust.
