Weight training made easy This dumbbell kit is ideal for anyone wishing to start weight training. It contains two barbells and an assortment of twelve weights. It allows you to increase the weight up to a total of 17.5 kg on one barbell or 15 kg on both barbells. The discs are made of plastic-coated cement. This plastic dampens the noise when you set them down, and prevents scratches on the floor. Thanks to the star-shaped clamping screws, the weights remain firmly attached to their barbells. The grip surfaces are knurled, providing an excellent hold, whatever the exercise. Detailed features: Practical, versatile dumbbell set for effective home training. Materials: plastic, cement.
