Was anyone able to sucessfully expand their ribcage?

Trying to expand it for bodybuilding purposes since it looks quite narrow compared to rest of frame the source i find that makes the most sense so far is this

Maybe but a small ribcage can be caused by bad posture and breathing practices so in theory it makes sense
