Im really not a beginner to lifting...but this is a newbie type question so im posting it here. Im talking about the area from the armpits down to below the nipple. Although i have a decent build (compared to average people), this is an area of my chest that is pretty undefined for me...whereas the inner portion for me looks better. Is this just a body fat issue? Or is there something i may be neglecting? For the record I do bench with more of a narrower grip on flat...and never do declines. Could that be an issue?
I work out at home and have no access to cables (in case someone was going to suggest that)
