Hey, guys. I was wondering how I could get my chest wider and more FULL. I have a fairly strong chest (bench around 335 lbs. for 3 reps), but it just won't grow like my other muscles do. I'm thinking it could be a genetic problem, but if so, is there any way to correct it? My workout consists of:

Flat Bench: 4 sets
Incline Bench: 4 sets
Decline Bench: 4 sets
Flys (with cables): 4 sets

I switch from barbell to dumbell from week to week. Someone I know suggested doing dips. Would that help my chest physique? Any other suggestions???
Thanks, guys,
MS
