Wider rib cage?

[BWalter]

Hey,

I have read (and seen) that guys typically develop broader rib cages during puberty. I'm almost 17 now, and my shoulders are nice and broad, but my rib cage is still really skinny. Makes it embarrassing to go shirtless.

So can I still expect a broader rib cage at some point?

you've got ~5 years till the end of puberty - you will completely stop growing around 22. It will probably happen. Try to look at your Dad, his Dad and your Mum's Dad shirtless (not in a pervy way - just if you get a chance). If any of them have very slim rib cages, you may have one too.

I would imagine that it should grow slightly wider. However, as BigBulge said, if either of your parents have a slim build then chances are you will too..

You may just have a small rib cage or it may soon grow it all depends on your genes
