uhh
Something like this?
Like I don't know how to explain it, so I won't even try. Just a wider oblique than is present on most people. Maybe I'm wrong, and over imagining it. Time will tell.
i actually am built like that
if you have wide hips it works real good, but i think this might be one of those unfortunate side effects of doing deadlifts, is that they hit your abs hard(obliques as well)
