what is your current routine and diet?
ALOT of people overtrain the shit out of their chest. you may or may not be one of them. i know at one time it seemed like everything grew but my chest. i dropped the volume and started doing incline first and i have made very impressive gains.
give us a little info about yourself and we can help.
My current routine Incline first like you said. 3 or 4 sets 8 to 12 reps
flat bench same sets and reps.
then dumb bell incline or dumb bell f;at bench
and cable cross overs
My diet is pretty clean I weigh around 175 and take in about 180 grams of protine a day I do like a good cheat meal. But I mostly eat grilled chickin and stuff like that.
