We (myself and a couple of other guys) where discussing this topic over in the HRT forum just the other day.
So, I'll paste it here to add to the discussion.
Of course, everyone has different goals. Mine is bodybuilding - period. I have, for all 26 years of my training, always trained for bodybuilding and that dictates what I do in the gym.
My routine varies throughout the year based on which of the three phases I am in at the time.
My three phase are - Heavy (6 months), Diet (3 months), Rest (3 months)
Heavy is focused on heavier weights and straight sets with more rest between sets. In this phase my calories are higher and I look to try to improve on weak points.
Diet phase is much more focused on supersets and dropsets with little rest. The idea is to work toward a semi-contest condition. Lower calories.
Rest phase is a time for experimentation. I try a lot of different things in this time with the idea of finding new ways to improve my train and I use this time to evaluate and set new goals. Your body always needs some downtime.
My Heavy Routine (which I'm in now) looks like this...(from last weeks sessions)
