Respectable lifts at the end of SS

Stretch marks between your pectoral muscle and arm (close to the armpit) are usually the result of bench pressing, I find.

I've seen some pretty specific stretch marks on myself and a couple of people around here, on the lateral/inferior side of the pec muscle, near the arm pit. I can't really see myself gaining a huge amount of mass in that very narrow area, it must be the arm position on the squats or something. I realized I was getting big when I got a stretch mark on my calves. Never got any on my arms or chest, but them by the bunch on the legs. They are mostly gone now.
