Experiencing something similar here with right sided pectoral atrophy. Pretty much cut off from sternal head... only clavicular left

Just wanted to keep this thread alive because it took me forever to find and it seems like there are others looking for answers. I'm currently 53 and in the last few years noticed a big gap in my chest. I can't say for sure when it first started, although I know I definitely didn't have it as a young adult (when I was working out all the time and posing in the mirror). The interesting thing is that my chest exercises (e.g. bench) have always been very weak and so I'm wondering if (a) there's a connection and (b) whether I've had whatever this is forever (maybe just not as bad) which affected my strength in chest exercises. My chest looks pretty much like Steiner's, a big horseshoe flat space between the chest muscles I do have. I've asked my doctor about it and he has no answers. He said there is no concern since it's not causing me pain or affecting mobility etc.

I do have some lipomas in my chest area and I wonder if that has affected the muscle growth.

If anyone has found any more information on this, including any way to address the issue, let me know!

Hi all, over the past 6 months I have got the exact same issue in my right pec. It has got exactly like the top image exposing the sternum bone.

The doctor seems to be clueless and has referred me to never specialist. I’m 21 and have trained for the best part of 4-5 year, then suddenly this happens. Want to keep this alive incase I get any answers for seems to be an undiagnosed injury. Frustrating!
