what worked to get my bench up..was to drop machines completely in my chest workouts
for flys use dumbells
and i also reccomend using dumbells for flat and incline presses..but thats your call.
make sure your training your back very heavy as well..because you need stability while balancing the bar over your chest.
If its your shoulders that are the weak part.and the reason your bench isnt up to par....make sure you use front head of your delt in your shoulder routine..make sure your doing front raises with dumbells..because that will help your bench when your lowering the bar to your chest...So burn the shit outta those front heads!
And if its the triceps, isolate the weaker tricep doing 1 arm skullcrushers laying down on a flat bench, or you could try the dumbell extentions that ronnie coleman does with one arm
hope that helps a bit brotha
