i would probably say i work my chest slightly too much. i approx bang out the same amount of sets that i do with legs. and also, i work em' every 6th day. i mean, i feel my body's pretty symetrical and i do not have a real lagging part over another. however if i had to pick up a body part to bring up slightly, it would be the chest. that being said, here's my present routine (changes, whether it be angles, order of exercises, reps...every 3 week/4 workouts or so)
(after thourough warmup with lighter dumbells)
4 sets incline barbell (10-8-8-6 reps, or there about)
2 sets incline db (10-8)
2 flat barbell (8-8)
2 decline db (6-6)
1 flat db (8)
3-4 sets weighted dips (6 to 8 reps, drop weight and do until bodyweight til failure)
3 sets hammer strenth vertical incline chest press OR 2 sets of a inlcine fly movement
thats approx 18 sets, trying to hit pretty much all angel at least for a single set.
