I am about 5'6" and have weighed 145 (walking weight) for 2+ years. I am trying to bulk up to 155-160. I try to eat more as well as work out to make sure i'm not gaining fat. But despite my efforts, every time I hit the scale... always comes out 145. I occasionaly drink protein shakes before or after workouts (never before AND after.) That's just a little history on myself. I think you can guys say i'm pretty cut right now, but i'd just like to bulk 10 more pounds. (wow that sounds hard). What are the general recommendations to increase weight and maintain good muscle definition? Someone know any good diet plans to help me gain this mass? Thanks in advance.
