Re: Decline Press - Who does this ?
When I'm barbell benching I do tend to do decline as I personally find it pinches the shoulders less.
That said flat DB benches seem fine. If flat is giving you issues go for decline and see how it works for you.
They both essentially work the same set of muscles despite what bro scientists might try and tell you about 'hitting the muscle from 56 different angles', so go with what is safest and most comfortable for you.
