This is my favorite routine for bulking or it can be adjusted for strength training. Check it out and see if it fits your goals.
Split Workout
Day one: Delts, triceps, abs
Day two: Back, traps, rear delts
Day three: REST
Day four: Chest, biceps, abs
Day five: Quads, hams, calves
Day six: REST
All movements are performed with PERFECT FORM (this is a must IMO)
All rest periods are short (60-90 seconds, 90 seconds being only for the BIG LIFTS - Deadlifts, Leg Press etc...)
All movements are performed as follows with a few obvious exceptions where it is not safe/ possible to do easily;
Set 1 - Warm up/ Feel Set
Set 2 - Feel Set / Close to failure
Set 3 - Working set (To failure and beyond, including forced reps, negatives, force negatives, static pauses)
*One thing to note is that you CANNOT REST DURING YOUR WORKING SET! You go to failure and then you carry on with the help of a spotter (still you must keep tight form as your spotter does the cheating for you), you do not stop and allow the muscle to rest and recover. Your tempo needs to remain there all the way to the death, DO NOT PAUSE AND ALLOW RECOVERY
Progressive Tension Overload
Progressive - Adding weight/ reps/ extra stimulus
Tension - Where that weight is going - on the muscle as tension.
Overload - Taking a muscle to failure - overloading the muscle with something it has not before experienced.
Progressive Tension Overload creates adaptation.
