Agreed! Do what works best for you. Everyone is different, you'll soon find out what type of rep/weight scheme your body reacts better too. For me, adding on my size this past year was pushing myself to the 8-10 rep range and using heavy weights. Depending on the body part - i would switch it up and go super heavy, focus on 4-6 reps. Usually only did that once or twice a month. And I usually mix in a good deload week too. Go light, give my body a break.
