Re: What's so dumb about curls?
Curls/cheat curls with 40% or more of BW do become compound as you have to stabilze your knees/hips/spine etcetc. At that level they become "full body".
It bitty pink dumbell level - not so much.
Id view them as similar to (but lesser then) the benchpress. A move that has a place if only hugely overrated by most "nonathletes" in the fitness world.
