The super durable Marino weights are made of a sturdy cast iron core with a rust-free chrome finish and can be used repeatedly for years without having to be replaced. The Rubber Coated Hexagonal Dumbbells provide a comfortable grip. A contoured and textured handle provides a stable and comfortable grip in your palms. The rubber-encased hexagonal ends of the dumbbell prevent the dumbbell from spinning around to cover whatever surface it lies on. With a few basic Meerut Gym and Gymnastic works weights, you can extend your strength training workouts to include curls, pulls, raises, squats, and more.
