I have a pectus carinatum deformation on one side of my chest, but the seemingly normal right pec has an entire part that just seems to have no muscle at all. I know I have a very long way in gaining muscle mass but I have been doing incline press and other upper chest exercices long enough to see some progress but it just seems to be an insane case of short chest insertion? It apparently happens on only one side so I just want to make sure if this is purely short insertions or not...
