The design is the classic hexagonal shape with characteristic colors on the ends that resemble a set of weights, making them easier to distinguish from a distance while also offering a beautiful visual result. However, internally it has nothing to do with traditional dumbbells. The interior of the dumbbell is made of steel and not cast iron like the usual ones, while the special way the axis is wedged at the ends makes it look like a solid piece, making it incredibly durable. The handle is non-slip, making the dumbbell become one with the hand.
