For the record I aced my Further maths on statistics once, so dont start. Lean gains gets exponentially harder this we all know. Heck if we can get 2kg/month now we all be happy. The human body gains naturally an average of 2lb muscle a month with average to good routine nutrition etc. However, please take the effort to READ properly that when I was on my newbie stage of working out and bulking, I estimated 12lb lean gains out of ~19lb in 3 months. Doing full body compound movements that I have never done before indeed shock my body to accelerated growth. These times its easier to attain progressive overload, correct? 4lb is not uncommon for newb biology, perhaps you can put a blame on my genetics? Probably you will argue what was my methodology for tracking this 4? I honestly admit that I solely based on commercial gym scales reports; two piece of report for consistency each measurement, once a week. I did not measure using tapes. I have a mirror and cam to track myself too? I dont need to prove myself btw

Apart from this, information overload is bad. We see many fitness articles here and there contradicting one another. If it works for me but not you then sucks to be you. Most importantly I keep them simple and do whats works BEST for me.
