ehhh.... i doubt thats 3lbs of muscle..
The body tends to bounce up and down about 5lbs in water weight a day...
Also, Its been proven that even the most talented and dedicated natural builders cant gain more then 10lbs of PURE MUSCLE in a YEAR!!! Its almost impossible.. so I really doubt u did 3lbs of LEAN MUSCLE MASS!!! But if you did.. then Congrats!!!![]()
