Ive got a problem it seems my chest is pretty developed but im lacking the upper chest and thats the part that makes you look sweet imo.

I do incline barbell incline cable and incline dumbells

now i was wondering if throwing in and low weight really high reps set in the beginning of working my upper chest would bring it out more?

id still do my regular workout but adding this

i do three sets of 8-10 reps moderate to heavy weight now
and im talking like maybe 25 reps something along those lines
