Decline bench strength versus regular bench strength I've noticed that my decline bench strength is greater than my regular bench strength. Is this normal? Is there something about my regular bench form that is off? I've always been weaker on the bench for some reason. I don't have a spotter and typically won't go more than 135lbs. On decline bench, despite doing it at the end of my workout, I can do 155lbs. 

I also notice that when I am doing dumbbell bench press I can do just as much as I can with the barbell. Other guys in the gym can usually do a bit more with barbell bench than with dumbbell bench. 

I am wondering if I have a form issue (sorry I don't have a video of me benching). Maybe it's a mind over matter issue? Also, my incline bench is the weakest bench (both barbell and dumbbell). 

I'd appreciate any tips, suggestions, or resources to help me out with this. Thanks in advance!
