I read an article maybe 10 years ago that described how a mans trade could be seen in his physique. Based on the craft and requirements of his job, the body would develop the necessary muscles. It was when labor transitioned to the offices and mental that the gym became a necessary aspect of fitness. Allowing individuals to sculpt the body they wanted. Previously it wasn't thought as necessary because you would receive all of the lifting needed through work.  

 WTH is KOL now?
