The flexible Hyperwear® SandBells made of neoprene can be used to do known and proven dumbbell and medicine ball exercises. Every SandBell is a mixture of a compact dumbbell and a large sand or fitness bag. Due to its form, the sand-filled dumbbells especially strain the grip force. The SandBells are available in nine different color-coded weights.
