My chest has been getting a lot stronger. With max bench and increasing reps but it doesn't seem to be growing or developing. I usually do flat bench with bar and then incline with bar or hammer strength. Sometimes switch it up and use dumbbells for both and then end with cable flies. Mid level and lower. I usually do chest Monday's was thinking of maybe adding some more Wednesday and do some decline and dumbbell flies. Will this help? Or do you guys suggest something else

I'm 27 weigh about 190.
Max flat BB 315 DB 130
Incline BB 245 DB 110
