I am also a programmer. I haven't worked out for a year, and the situation at first was similar to yours. As the saying goes, "hands can't tie chickens." The bench press is still heavy, but now I can add 40 kilograms of weight plates. Don't worry so much, just keep practicing, sooner or later my weakness will be made up.

If your hands sweat too much, bring a pair of fitness gloves. They are non-slip, but they feel worse, hehe.
