A few notes: I combine my tricep and shoulder exercises. On tricep days I do a shoulder exercise and one tricep exercise with no more than six total working sets. On Bicep and back day I do a total of no more than six working sets for biceps and never more than nine working sets for bi's on non-back days. I do no more than ten working sets for major muscle groups. However, I do ten sets for calves since it's my weak bodypart.
When Bulking I focus on the eccentric and work in the four to eight rep range with a four second cadence for each rep. When dieting I work in the eight to twelve rep range with little rest between sets at a faster cadence. I also never do the same workout twice by changing exercises and order of each exercise. Although the barbell bench, squat and deadlift are a staple.
If you keep a training log you will be able to determine exactly what works for your body. I've found this works extremely well for me but individuals vary and that's why experimenting is so important.
