You can adjust the weight to suit your physical strength. From beginners to advanced users, you can perform strength training at home. Beginners and women can use it with confidence. 【Doesn't damage the floor】 The outer material uses durable polyethylene. Unlike iron, it's less likely to scratch the floor even when placed directly on it. Even if the dumbbells collide, there's no "clanging" sound, so you won't bother those around you. 【Safe screw-type collars】 The non-slip collars use a screw-type design to prevent the plates from loosening and falling off. You can perform strength training at various angles, ensuring safety during your workout! 【Dumbbells that don't make your hands cold in winter and are easy to use】 Even without gloves in winter, your hands won't get cold or hurt! You can grip them firmly, and they won't dig into your hands, even with heavy weights. The design naturally fits your hands and is easy to use! Assembly is easy, just insert the plates onto the shaft, and they can also be removed for easy storage! 1.0kg x 4 + 1.25kg x 4
