You are telling me that as a natural advanced lifter you can put on 14lbs of lean muscle mass in 6 months? Or are you talking 14lbs of body weight?
Not all lean muscle, However to see significant changes in your physique you must make a significant change in BODY WEIGHT
Alot of time Natural lifters think they have hit a wall, when in fact they simply are not adding body weight like they were during their "newbie gains" and this is because they simply are not putting the effort in with the diet.
Alot of guys think they are eating alot, but in reality they may eat alot one day, then just hit maintinence for the next few days.
If you are consistently eating slightly above maintinence then your body weight will shift upwards and you WILL SEE CHANGES IN YOUR PHYSIQUE.
Q for u : I assume you think you have a hit a wall? The past year you feel like you have nto made the changes that you made when u first started? I was exactly the same.....then i realised.....i had been (give or take 7-10lb) the same weight for about a year.
Once i started eating consistently the weight started coming on....and guess what....my physique started changing.....the bigger you get, the more food you have to consume.....and most people have a problem with that.
Bottom line : WANT A SIGNIFICANT CHANGE IN YOUR PHYSIQUE? ADD BODY WEIGHT SLOWLY BUT CONSISTENTLY.....its HARD WORK
