next time you work chest, warm up, then put 225 on the bar and rep it till you cant lift it no more, then rack it, run over to the dumbells and grab them and hit them for about 8-10 reps............see what kind of burn and pump you get........do this for about 3 sets, since you are supersetting that with db's that will be 6 sets of flatbench to start, a good way to start your workout, try it sometime just for a change!
