How wide could I potentially get as a newbie? 20 inches atm with ****ed up shoulders.

[Vrak]

Hi. I am looking to get back into my strength training after too long a hiatus but this time I want to focus on some aesthetics as well.

I have 20 inch wide shoulders at the moment as a non lifter, no muscle development, about 20% bodyfat at 200 lbs, and my shoulders are extremely rounded.

How much could I add to my width by un-rounding my shoulders and then packing on some muscle mass?

I read an article where it says rounded shoulders can take inches off your width?

Could I expect to get my width to 23 inches? That's my goal. 1.5 inches on each side. I think it's very achievable especially considering my rounded shoulders, but I am new to all this and really don't know much of anything about it.

Any insight would be appreciated.
