Muscle fibers either contract or they do not. There is no partial contraction and the muscle fibers in the "inner chest" go all the way to your shoulder. Inner chest development suggests you are growing a muscle fiber unevenly on one side, that just logically can't happen. At least in the upper lower argument the whole fiber is suppose to be growing.
This +1.
If your "upper inner" chest isn't as pronounced as you'd like you just need to put on more muscle. Your genetics have given you a certain muscle shape, theres not much you can do about it besides grow and see how your shape reveals itself!
there actually is an inner and outer bicep. That's why it's called a BIcep
I do a lot of incline work already. barbells and dumbells and a few machinesdon't overanalize!!!! Just do some incline press. Incline dumbbell would be a perfect solution.
He split it down the middle. Check it out.If you mean there is one on top and one underneath, I agree. If you mean there is one closer to your body on the inside of your arm and one on the outside further away then feel free to show me an anatomy picture of said muscle with a split in the middle.

fuck yeah im probably around 10% right now. Ill just keep pressing hopefully it will grow!How much bodyfat do you carry? if you have less than 10-11% and still have weak upper chest, it's probably genetic.
It is true that genetics ultimately determine your weak points and problem areas, but to say that you cannot train a certain part of a muscle group is simply not true. Take delts for example...if I only did rear dumbell flys, do you think my anterior delts would develop as quickly as the posterior? I think not...
In the same way, to say that you cannot specifically target the upper chest to stimulate growth is ridiculous.
Ya, we call the deltoid one muscle but it's really three separate things. The chest is two muscles, but the "upper" chest is the same muscle as the lower chest. That's like saying I can train my outer traps. How do you increase part of a muscle without the whole thing growing?Of course not - but that's not the same thing at all. The rear delt and front delt are two different muscles with different origin and attachment points. The pec major is one muscle with no divisions.
