For about 2 months now or so i have been working out using about 12 sets for the big muscles (Chest, Legs, Back) and 6-9 for the smaller groups (Biceps, Triceps, Shoulders) and my body has just grown like crazy (Like scotty said it would). I have never experienced such growth in my life. But my question is with doing this few sets with each bodypart, are the muscles less likely to plateau out and not grow anymore, in which a person would have to switch up their routine? Because I have done the same workout (a four day spilt) for almost 2 months and I go up about 5 pounds a week or 4-8 reps per set. Now once i reach 10 reps on a particular weight i up it five pounds. My diet is pretty good but will i continue to go up like this? And if so should i ever switch around my workout if i continue to grow? Thanks for your help.
