I had some very good results with push - pull methods; did supersets and negatives. My routine was kinda like this:
Arms
Chest/Back
Legs/Shoulder
For arms:
Biceps curl negatives, 3x8
Superset
Triceps overhead extension negatives, 3x8
Biceps on the machine negatives, 3x8
Superset
Triceps rope negatives, 3x8
Preacher Curl, 3x6
Triceps V bar, 3x6
Back/Chest
Assisted Pull ups negative, 3x8 (I would put a higher weight and then take my feet off the step and then do a negative, place my feet back for the way up)
Superset
Bench Press negative -with spotter -, 3x8
Smith Row negative, 3x8
Superset
Incline DB Press negative -spotter-, 3x8
Deadlift, 3x6
Superset
Decline DB Press, 3x6
For legs it was just regular, same as shoulders. Would do Hack squat, Leg Press and Leg Curls, and shoulder would do lateral raises and overhead presses.
I had very good success with this, especially where arms were concerned. They showed the most development that's for sure.
