im a pretty small guy and dont lift the heaviest of weights as a result but i have seen some pretty good gains. however, the interior part of my pecs (i dont know how to describe it well) but the area by where the pecs come together refuses to develop for me. i cannot see or feel any muscle developing there. i basically bench and do different variations of flys when i am focusing on my pecs. is there some other excercise i should use to help develop this part of my pecs? thanks a lot for any help
p.s. i attached a picture and tried to circle more or less i am having trouble making visible gains. thanks a lot
