I need some new excersises

I need some help developing my lower and inner chest. I'm having trouble finding excersises, other than decline bench, that do anything. please post any excersises you might know. Thanks,
Bull

dips, dumbell flyes

incline dumbbell flies seem to work well for me for building total chest mass, i don't know why.

preexhaust your chest with flat bench flies before doing pressing and you will find your chest gets more fatigued especially if it is weaker than your tri's.

Low pulley cable flies with D-handles and flex like crazy for about 3 seconds at the end of each rep

try performing dips like 23 mentioned
