Hello, the width of the shoulders is determined by the skeleton, which is innate and cannot be changed.

(Although it can be reshaped through osteopathic surgery, it is too expensive)

So if you want to make your shoulders wider, you can only use the shoulder muscles to reshape them.

Persist in doing 50 push-ups every day, two sets in the morning and evening. If you insist on it for a year, you should be able to achieve what you want.
