Hi im new here. I'm 17, gonna be 18 in a month, and im 140 pounds. I have been working out since February of this year, and i gained about 10 pounds of muscle mass. Then i changed to working out like Arnold (hehe) I bought his encyclopedia on modern body building, and i haven't gained a single pound of mass since February. I look a lot more cut, but no bigger. I assume this is because i moved from low reps high weight, to high reps lower weight. And i am about to make the move back to high weight lower reps. I was benching 135 in my routine when i ended high weight, now i bench like 110 in my sets. This is how i currently look, and i would like to be about 190-200 pounds in a year if possible.
As you can see i am defined but i am slim, i would like to gain as much mass as possible and i just wondered if going back to higher weight and lower reps was the right way to go. thanks for your input in advance.
