Did you even think about this before you posted, I mean seriously, I mean even if you had absolutely no knowledge of weightlifting what-so-ever you should still know that this is so far from impossible its not even funny.
I mean lets do some simple math, lets take the low end of his number, 5-10 pounds, well take 5, no instead lets take 4 pounds in 2 weeks.
Hmm over the course of a year 4 pounds every 2 weeks would be 104 pounds of mucle a year. Thats funny, cause that means that if I followed whatever routine someone was going to give you, that I could be bigger than Ronnie Coleman, and win Mr. Olympia with ease.
Hell even 1 pound a week with beginner's gains is unfreaking believeable.
Why dont you go back and evaluate your motives, if you plan to lift until you reach your goal and then stop or slack off, then weightlifting and/or bodybuilding is not for you. Its a lifestyle, no matter how small or extreme your goals are its still a lifestyle.
I just can't stand when people come here and want a quick fix to something, and expect this stuff to be easy and then they quit after 2 weeks cause they dont have the determination or the motivation to keep it going.
