This is my weekly workout routine, but is this good or is this bad?

i think you should mix it up more and not do the same routine because you're going to plateau eventually. also, 5 sets is too much. 3 is a good number. i wouldn't limit yourself to just 12 reps. what i mean is that if you can push out a few more, do it. don't be so fixated on how many reps you're doing because you won't grow that way.
