Long arms/weak inner chest

[scottyshotty]

I believe because of my long arms it is hard to isolate my inner chest-very weak point. close grip bench, pec dec and cable crossovers dont seem to really isolate it well. im trying to find an exercise that I can do with my long arms to make the very center of my chest burn with fury. Ive tried all heavy lifts but I think if I can find the right exercise I will do 100s of light reps of agonizing pain. I believe this is my only solution. Any feedback or similar situation? thanks

Well I isolate my chest very well with butterflies and really squeeze at the top of my reps.

If you have long arms then you get a better ROM on your pecs, and you can't isolate the inner chest.

There is no inner chest. Sorry.
