Not really, can't read in-between lines. My English is not that good.
Do you mean that a PLer uses many muscles when benching but a BB has healthy shoulders?
I do flyes, I feel like I am hitting more my chest with them than when benching, I do crossover cable too. But I want to learn how to bench ok. Sometimes I feel like my shoulders and triceps are working more than mi chest and I get piss.
Thanks for your time bignate.
