How in the world do you build the inner chest? Can't seem to be growing in any form.

you can do rotations of different kinds of pushups, over time it can add some muscle mass but if you wanted to bulk up you'd need to do exercise with equipment. or you could go on a calorie deficit+working out for a longer period to develop a more lean body with more defined muscles.
