Arm Exercise with 20-Kilogram Dumbbells

Anyone who has this or a similar idea and wants 20 kg—while currently owning only 5 kg or 10 kg—should know that I don’t need it at all; I’m cautious. It turned out to be too heavy for a beginner: the 20-kg version didn’t benefit me due to excessive weight. Its market value is approximately 60 SAR for 20 kg. Those who wish to buy it for 40 SAR.
