I have been doing a 5x5 routine since Feb. Being that the routine has you doing 5x5 for 4 weeks and 3x3 for the next four. I thought that would be enough to keep my body guessing. However, I think I may have hit a plateau as my lifts especially my chest are not going up.

Do you think a change in routine is in order? I was thinking doing some of the wannabebig methods. What are the results on this? Anyone gained any serious muscle? I have heard many "newbies" say they have, what about experienced lifters. I have about 10 years under my belt.
