In the picture you can see where I marked in red. For as long as I can remember (over a year), when I workout chest it makes this part of my arm sore. If I do incline bench first, then my first set of 8 is ok, but on my 2nd set it starts to get really sore here, and even worse on my 3rd set. (the pain happens with ALL chest workouts - fly , decline, flat, dumbbell press). It a huge problem since I have to stop before my CHEST is fatigued.. the pain makes me stop.
I have tried:
-Lower weights - does not help, it still starts hurting on 2nd set or so.
-stretching - doesn't seem to help at all (although, I am not very flexible)
Please let me know if you have any advice. It feels almost like a connective muscle or tissue.. It is not right on the edge of my armpit, but almost in 1 inch from the edge (where circled).
