Mike Mentzer was born in Germantown, Pennsylvania, and was something of a bodybuilding renaissance man. Renowned as much for his vocabulary and propensity to quote the philosophy of Aye Rand as he was for the dimensions of his Herculean physique, Mentzer established himself first as a bodybuilding champion and then as a scholar of the sport. Having placed 10th at the 1971 AAU Mr. America contest, Mentzer came in contact with Arthur Jones, who at that time was promoting his less-is-best training theories along with his Nautilus exercise equipment.
