Its design is the classic hexagonal shape with distinctive colors at the ends that indicate the weight group, making them easier to distinguish from a distance while also offering a beautiful aesthetic result. Internally, however, it is completely different from classic dumbbells. The interior of the dumbbell is steel and not cast iron like usual, and the special way the shaft is wedged into the ends makes it appear as a single piece, making it incredibly durable. Its handle is non-slip, making the dumbbell feel like an extension of your hand.
