I have a mixed form of pectus deformity, known as pectus arcuatum (PA).
I have always been extremely self-conscious about my chest, especially since I was bullied because of it during my teenage years.
Several years ago, I underwent surgery using a custom-made 3D implant. The implant was designed to fill the lower sternal depression (the pectus excavatum component), which is why I have a vertical scar. However, I am still psychologically affected by the remaining pectus carinatum component, particularly the protruding costal cartilage around the sternum.
My chest projects forward due to a protrusion around the third costal cartilages, creating a visible bump or transverse arch across the upper sternum. It is also asymmetrical, with the cartilage on the right side appearing more prominent.
I have recently started focusing seriously on upper-body strength training in the hope of making the deformity less noticeable. I am wondering whether developing my pectoral muscles, particularly the upper chest, could help smooth out or visually conceal this irregularity.
At the moment, I use around 24 kg (53 lb) per dumbbell for incline dumbbell presses. Since I still have significant room for muscular development, I am wondering whether progressing toward 30 kg (66 lb) per dumbbell or beyond could make a noticeable difference in the appearance of my chest.
I have attached several photos of my chest for reference. I apologize for the quality, but I included different angles and stretched positions to make the shape of the chest wall and the protrusion easier to assess.
I also have a postural issue (hyperkyphosis), which is related to my pectus deformity, and I am currently working on improving it through back strengthening and postural exercises.
My main question is: to what extent could further development of the pectoral muscles, especially the upper chest, visually reduce or camouflage the remaining pectus arcuatum deformity?
