Alright, I'll get straight to it. I am 20 years old, 5'10" and 150 pounds. I don't know my exact bodyfat% but it's around 11%, I am pretty thin so fat is not an issue. I've been working out for a little over a year now. I was 130-135 pounds when I started. I've always had a hard time gaining weight. My goal is to just increase my gains, maybe 20 pounds in 4-5 months(is that realistic?). I am starting the german volume training(I am satisfied with my training but if you disagree with the workout i chose feel free to comment) once I get my diet in place. I still consider myself a rookie in the bodybuilding world so I need a little help. If you could help me by adding, eliminating, changing anything in my diet I would appreciate it.
