I am nearly 100% certain this is due to me sleeping on my side my entire child hood even to this day. My rib cage seems to be more pressed together on the sides making the front stick out slightly... if you were to look at me youd never know its nothing noticeable by anymeans. However the very bottom of my rib cage on the font is visible and to me it is messing up an appealing flow from my pecs to my abs. I am still young and i can tell that my ribs are still quite flexible and not fully developed, do you have any suggestions?
