Is this number of sets ok?

I just happen to notice that most people recommend or give out workouts consisting of only 9 sets per muscle group. So I was just wondering if doing 12 sets per muscle is ok??? Like for chest, if I do:

DB bench press 3 sets
Incline BB press 3 sets
Decline DB press 3 sets
DB pullover 3 sets

I normally do low reps (4-8) for a couple of weeks and then high (10-12) for a week, then back to low reps.

Is this too much or not??? Or is it in the borderline???

it would be too much for me i prefer 8-9 but have you been responding to it well?

drop the pullovers then you are sweet

Well, that gains are coming. I can't quite say that it's great but it's there.

So you're saying that 9 sets is really the way to go?
