extra chest set on shoulder day

[nj123]

I am not happy with my chest development. Do yall think it would be a good idea to add in one exercise for chest every week on shoulder day. Like one week i can do flat bench and the next week do incline bench. My chest day routine right now looks like this
flat dumbbell 10-8-6-6-4
incline dumbell 10-8-6-4-2
decline hammer strength machine 10-10-8-6
pec deck 10-10-10
sometime ill add in incline fly's too because my upper chest is weak.
Im using mostly dumbells because one of my tri's is alot stronger than the other

Chest is one of my most stubborn bps. Anytime i feel like i hit a wall with developement ill change my routine up and have the base of my workout be regular flat bench. Ex 1st chest day of the week:8 sets of flat bench 4-10reps pyramiding up. 2nd chest day: Focus more on concentration movements and chest stretching exercises with less weight near 60% of your max. Works great for me and im sure youd be happy with results after a few workout cycles bro. Let us know how it goes.

do you mean work chest twice a week or do you mean do one heavy week then one light week? Also when you say pyramid up you mean like heavier to lighter right?
