2" in one year is incredible! This is something that is possible today that was not possible back in the day. I remember when men would think gaining a half inch in 2 years was a great accomplishment, when I saw this I thought what is the point of working all that time for 1/2"?!? Anyway, I would not accept those terms and I was determined to prove that with more intense exercises, super sets, sequential training, progressive routines, and a lot of erect work. I was able to make a 2" gain in 6 months shattering that glass ceiling. Today big gains are expected and with the various tools today, how can you go wrong?
