Heavy presses work for sure.There has been some disagreement as to laterals being effective in a DC program,but I think it works well.Your supposed to pick 3 exercises to choose from and alternate 1 for each delt workout.For me it was behind the neck presses,hammer strength presses,and side laterals.
The day that I did laterals was my favorite.After my chest work was done,id warm up my side delts with some light laterals to make sure they were full of blood and ready to work.The on to the 1 big rest pause set
It looked something like this...
60lb DBs 10 reps to failure
15 very deep breaths,probably 25 seconds rest then the 60s again, got maybe 6 this time,15 deep breaths,and then 1 final all out set with the 60's again,maybe 3-4 reps
At this point the delts would be on fire and so full of blood you cant lift your arms.But if you really want to annihilate them further(not possible most of the time),then once in awhile when i had extra energy I would rest another 15 deep breaths and then grab 30-40lb DBs and bang out as many reps as possible.I can promise you the pump cannot be imagined.
For me laterals are a great part of the DC program.Especially after a heavy incline bench "rest pause" set.Your delts already got hit from the pressing movement,now your just finishing them off....
