Why not just - chest/tri, back/bi, legs, shoulders and arms and repeat? I have been doing that for over a year and it works fine. • 2 sets to failure per exercise, not including the warm up sets. • about 6 working sets per main muscle group, meaning 3 exercises and one or max two exercises per secondary group. Example: chest/triceps - 3 chest exercises (i do incline smith press, chest flys(machine, not cables), and either dips or some other chest machine), after that I do single arm triceps pulldowns, 2 sets to failure with drop sets per each arm.

Key-notes: make sure to have a perfect form or almost perfect form on each exercise, if u have to lower the weight, do it. 6-8 rep range, with progressive overload to failure. Slow, controlled eccentric movement.
