After years of doing a bodypart once a week, I am going to switch to something completely different. I used to do (eg.):
1 chest/shoulders
2 legs
3 bis/tris
4 off
5 off
6 back
7 off
Now I am going to try (eg.):
1 upper chest, heavy delts, 1/2 tris (basically only half the exercises I would do for a bodypart on a given day)
2 quads
3 1 heavy back exercise, 1 light back, barbell shrugs, barbell curls, dumbbell curls, wrist curls
4 off
5 lower chest, lighter delts, other 1/2 tris
6 hams
7 pulldowns and isolation back exercises, dumbbell shrugs, more "isolation" bis exercises
8 off
Basically, my reasoning is that I am not gaining enough solid mass during my cycles. While I use to feel like I needed the week off, lately I have been feeling like it's too long and I can handle it. I have been peaking at about the same point in my cycles, and need to change to blast through this plateau.
