It's often said swimming makes your shoulders wider, perhaps breaststroke and butterfly in particular? Are there any real swimmers here who can confirm this with their personal experience?
If true, what length of time and intensity of swimming did it take to result in such changes? I suspect this can happen only to competitive swimmers.
When you say "wide shoulders" what do you really mean?
Do you mean broad shoulders - with a big upper body bone structure? Perhaps a big difference between chest size and waist size?
Or do you mean prominent deltoid muscles - the basic shoulder muscles?
I don't think someone who doesn't have broad shoulders (skeletal structure) by the time they are 18-20 can develop them later. Your bone structure is essentially finished development by that age. Deltoid and other muscle development can occur for a long time so I think an adult who starts wimming at 30 could develop big shoulder muscles. But their chest or shoulder width won't change.
