To all you guys out there I'm sure this has been brought up tons of times but here it comes. Upper chest lacking I've read so many times change workouts, hit upper chest first thing. I still fall short of getting a rreally good upper chest idk what the deal is!? I really wanna fill out my chest. Also when I perform flies I honestly believe I'm not getting the full effect as hard as a try to hit good form! What are some tips here?? Also I read about decline bench. It stimulates the same part of the pec as regular bench also and some upper pecs! Do some people just do decline??
