I wanted to ask my trainer, but he is hard to talk to.
My right shoulder had been giving me a little pain during my BP, he has me doing only decline right now.

It was fine today, but my left one has been hurting as the day went on with the same kind of pain? I've been pushing my personal bests each session,.

Am I going to hard? Likely bad form? Any suggestions? Don't want this to get worse.
