I read that the upper abs are used in most movements, every time we bend to pick something up so deadlifts and similar moves would work the upper abs well. I also read, whether or not there's anything in it, I don't know, that isometric abs work is better for strengthening the abs for heavy lifts...like I said though, I have no idea if that makes any sense.
I fully agree with the first part, the upper abs are made use of a lot, it's the lower abs that aren't really taxed; it probably also accounts for why the upper abs tend to be prominent on most people and why they struggle with the lower abs definition and size.
