The important thing to note is that from the medical perspective most experts believe that this is no longer possible once the ribcage sets at the end of puberty. Arnold believed that expansion is still possible after this point , albeit much slower.
Keep in mind that males even after they've stopped growing taller, do broaden for a few years afterwards... Extremities are the first thing to grow larger, and the chest is the last thing.
Myself personally having a large rib cage now...
Between 18 and 23 my chest increased about four inches, and my shoulders broadened about the same. I went from having a "Boyish" looking chest to a manly looking chest. while losing fat. And while I did have some physical labor jobs, it sure wasn't all from built muscle.
I would guess that doing chest work, adding muscle and increasing bone density, at this the end of your growing years, might have a little bit of an effect towards increasing your frame size.
As it makes sense that a growing bone, even slow growing, will be stimulated to grow a little larger, by putting more mass on it, and giving it more demanding jobs that it would increase to meet the demands
But regardless it isn't going to be anything really significant.
In my case I come from a background where both sides of my family are big chested. Heck my grandfather, who worked building a railroad, then built houses, and retired as a house painter, died at 6'6" 285 pounds, and damn near had a six pack!
Stupid ectomorphic genes just had to slip into my mix from my grandmother through my Dad to me!
But all the above is just my layman's oppinion/observation.
"This is where man finds himself these days, 10,000 years in the making. 10,000 years of endeavor in science, the arts and humanities. And within one generation he's been reduced to a feckless, bed wetting, parmesan shaving imbecile who revels in his own uselessness... Something has to be done." -James May
"The place to improve the world is first in one's own heart and head and hands, and then work outward from there."

your ribs are attached to your sternum by cartilaginous tissue. it was believed by many old-time bodybuilders (particularly Arnold) that pullovers stretched this cartilage, and could therefore expand the overall size of the rib cage.
as far as whether it's true or not, i don't really have an opinion. :/
A resounding NO for all the above reasons. If it appears the bodybuilders of old appear to have "wide ribcage frames" it's probably because they also had narrow waists unlike the bloated, distended stomachs of today's bodybuilders. Pullovers (DB, machine or cable) are a great exercise IMO and have their place in a BACK routine versus chest as they primarily work the lats as well as the serratus. Unfortunately because of this old piece of mis-information they are often overlooked as an exercise choice.
Expanding the rib cage means growing bone. Growing bone means it's possible to become as tall as you want. That's impossible once puberty stops, so your argument makes no sense.
You want big muscles, girly man? Find big rock. Pick up big rock. Raise big rock overhead. Repeat as neccesary.
I really want a totaly toned flat chest, however after working out for nearlly 6 months now my pecs are getting bigger!! My chest workout involves flys and various bench presses and I'm steadily increasing the weights that I use but not too sure if I should be doing this. Can anyone help?

We are not talking about growing bone? There is no argument ?
