first of more than likely ur shoulders are bad from benching with bad form. Start warming up rotator cuffs and also strengthen rotator cuffs at the end of the workout. make sure ur push/pull movements are balanced in ur workout. Face pulls and rear delt raises are ur friend... Also watch dave tates 6 week bench cure bench like that doesnt matter if ur a BB or a PL. personally id drop incline till my shoulders felt better because they stress shoulders more.
