Durable Hand Weight - The cast-iron hand weight dumbbells are ideal for light weightlifting and muscle toning on a daily basis in the comfort of your home gym or at fitness classes. They area available in a variety of weight levels. Non-Slip Grip - Our neoprene dumbbells have a shell that provides a comfortable non-slip grip. The neoprene covering helps to stop damage to your floors and avoid chipping on the weights while the smooth texture is comfortable to hold. Hexagonal Shape - With a classic hexagon shape, this helps to keep the weight from rolling and stays in place when not in use. Combined with the neoprene shell, you won't need to worry about your weights rolling on your floors.
