East West Dumbbells are designed for functionality and safety in all ranges for movements. Whether it be biceps curls or renegade rows with the hex-shaped design we are able to create stability and prevent rolling. In addition, our dumbbell handles are made from steel with a knurling pattern etched into the handle for a secure fit while in use and the head of the dumbbell is made from pure rubber with a steel core, limiting noise, reducing impact, and reduces accidents when the dumbbell is dropped.
