Per dumbbell
Log the weight of ONE dumbbell, even when using a pair — 12.5 kg dumbbells in each hand is 12.5, not 25.

Programming notes
Dumbbell Shrug is driven by the traps, with forearms assisting. Give the primary movers roughly 54 hours before loading them hard again. In the same session it pairs cleanly with Barbell Bench Press, whose primary movers don't overlap with anything this exercise works.
