How many times do we have to say this?
You can’t change your genetics. You can make your chest muscle larger,
but you cannot change the shape, where the muscle insertions / attach-
ments are, unless under a surgeon’s knife, and that rarely proves satisfactory.
The “inner chest” muscle you refer to will grow in proportion to the remainder
of your chest. You cannot develop, target a particular part of the muscle at
the exclusion of another.
Now . . . you can continue spinning your wheels in the sands of time, doing
every routine in the book, every exercise known to man, and some that have
been invented yet . . . , following everybody’s else’s advice (with no proof I
might add) or you can find the exercise(s) that are best for you and use
proper form, and get stronger, and let mother nature do the rest. The hardest
part may very well being happy with the results. Not many people are.
I would love to see one person here on this thread post a photo of their chest
development, and the development they can attribute to their advice. Trust
me, it won’t happen. People like to talk the talk, parrot everybody else, but
few can back it up.
Attached is a foto of Franco Colombo at 24 years of age. Notice he had that
split in his chest back then, and I would be willing to be bet if you saw a foto
of him at 12 years of age, you would still see that tell-tale split in his chest.
He did not get that from exercising, he was born that way, and he potentiated
it through weight training. As his entire muscle got larger it became more
noticeable.
