For chest/triceps I usually do the following:
Bench Press 1x12,8,4,1,failure: Lately the weight has been: 185/205/225/240/135 (usually I get about 20 reps for the failure set)
One arm cable tricep extension 3x10: 30/35/42.5
Dumbbell Press 3x10: 65/75/80
Dips 3x10: ya
Incline Press 3x10: 135/155/185
2 arm cable tricep extension 3x10: 65/72.5/72.5
Abs if I feel i got some energy still, some days I have it other days i dont.
That was my most recent chest/tricep workout. My rule of thumb for most workouts is whichever muscles i target I do 3 exercises for that muscle group. For back/biceps I do something similar.
