Try working out with dumbels give your body a bit of a shock. to me its a whole new world.

Incline dumbel press 4 reps of ten
Decline Dumbel press 4 reps of ten
Flat bench dumbel press 4 reps of ten
Do a set of wide grip inlcine or flat barbell presses these kill!!

I usually do 3 sets of the pec machine till exhaustion
