If you're training for size now LiE, just stick to 3 or 4 sets per exercise, at 8-12 reps. When you find you can do 12 reps without a struggle of that exercise, up the weight by 2.5-5kg
I never stick to the same sets or reps each week, I mix it up all the timekeeps your body guessing and keeps it all fresh
I'm not sure that's the best way to be progressive though, it has the potential for you to be lifting the same weight for a while. By starting lower and building up you'll be able to keep going longer.
