Weird Chest, Inner Growth?

just wondering if anyone else out there has a weird chest development. i recently got my chest to start to grow again, but it seems to only build up on the outside next to my sides and up top, how do i get it to grow in the middle so i dont have a big gap in between?

That big gap is your sternum. It is solid bone. You will not be building muscle there. What you can do is make your chest way bigger all over so that is less noticeable. You can not change muscle attachments.

pec deck or machine flies is good for inner chest, as unnbelievable as it sounds. of couse there is a gap between pecs

Ring presses and flyes.

thanks guys! I just find the gap looks wierd
