Set of 2 x 20kg (40kg total) [Polyethylene Dumbbells] Maximizing the potential of polyethylene material. This is a versatile training tool that can be used as both a dumbbell and a barbell. [Less likely to scratch floors and quiet] The outer material uses highly durable polyethylene, and the design is circular. Unlike iron, it is less likely to scratch floors even when placed directly on them. Even if the dumbbells collide, they won't make a "clanging" sound, so you won't disturb others.

With the extension shaft, it can also be transformed into a barbell! With a flat bench, you can try any kind of training.
