i remember buying the heavy duty mentzer manuals back in the day also, my neighbor gave me the old arnold training manuals he had from the 70,s also. i cant find the arnold ones, ive must have lost them and it sucks cause they would prolly be worth some coin today.i used to train with bill grant alot and he would tell me how him and arnold used to train, the stories bill use to tell about those old golds gym days in cali where priceless. im actually gonna see if i could find a time machine to go back to the early 80,s when bodybuilding and life in general was better,lol
