I usually do 3 excersises for chest. Flat barbell bench,dumbell incline, and weighted dips.then next workout i will rotate dumbell flat bench,incline dumbell press and decline press.First excersise i usually do 2 warmup sets and 3 work sets (4-6 reps) the rest i'll do 2-3 heavy sets(4-6) reps.No need to warmup again on the rest of the excersises,your already warmed up Low reps seem to work the best for me. sorry for the long thread
