ok, im 5'6, a little stocky, but not where i want to be. most of you know how the short man build looks. and im trying to reach that. my diet is down and im eating my essential carb/protein/fat intake to grow. but now my question is training. should i be training LOW reps heavy weight? or what? i usualy do 4 sets 8-12 reps, but i have heard doing 3-5 reps with heavier weight builds more bulk muscle, fact?
