Pec/Ab workout

[red92gt]

Right now these are my workouts for pecs and abs:
Pec-Benchpress on a negative incline, 3x7 with 1:15 in between (will have to alternate that in a while, suggestions?)
Ab- Incline situps with weight on my chest, 3x12 with 1:15 rest. I would do less reps and heavier weight, but the 45lb takes up my entire torso and makes it difficult. I'm trying to stack 35's, which is a pain.

Question is, does anyone have any better workouts? The abs are doing somewhat decent, but for as far as pecs go I'm getting results but not quite what I would think I should get. What does everyone else do?
