When I first started lifting weights about 3 years ago I couldn't get my bench press over 200 I started doing dumbell presses for awhile and the next time I did bench I went from barely doing 200 to benching 225 4 times. This was when I first started working out. But, even today I rotate dumbell presses every 3 weeks. Maybe you should change up your reps for your bench do powerlifting sets like 10,8,6,5,5,3, even though it seems like a lot of sets it works and wonce you get some strengh you can do bodybuilibng sets
