Rubber Dumbbells

Rubber Dumbbells are fixed-weight dumbbells with heads encased in rubber, often virgin  rubber, over a cast iron or steel core, paired with chrome or steel knurled handles. Common styles are hex, round, 10, and 12 sided heads, and are ideal for all dumbbell exercises. They're a staple in home gyms and many commercial facilities for their affordability and practicality.
