Ditillo's lifestyle made it possible to train that way. I knew a guy that knew him a little in NJ, and he mentioned that Ditillo's main job was running the family diner in Elizabeth that was close to his house, and he kept a rack and some equipment in a backroom, and he'd use it to get extra work in.
His mentor was Dezso Ban, who was an Olympic Lifter for Hungary, circa late 40's, early 50's. So a lot of his philosophies were based in that sort of keep grinding till you give out mindset.
The actual Dezso Ban -

I do remember Ditillo mentioning in an article that he flirted with "Growth Drugs" a little, but he didn't really go into it.

Dezso Ban's obit (May 10, 1930 - Oct. 24, 2013) -
Dezso Ban, 83, passed away on Oct. 24, 2013, at Pocono Medical Center in East Stroudsburg.
He was born in Budapest, Hungary, on May 10, 1930, son of the late Mihaly and Julia Banlaki. Dezso was the loving husband of Susan (Alcorn) Ban. They celebrated their 15th wedding anniversary on May 11, 2013.
Dezso served in two armies in Hungary, worked as a butcher, and most important to him, became an elite Olympic weight lifter before emigrating to the U.S. in 1956.
He received his bachelor’s degree in physics from Seton Hall University in 1978, and his master’s degree in physics from Fairleigh Dickinson University in 1983. He had an extensive reading interest in linguistics, mathematics and physics, and his love of weight lifting persisted throughout his life.
He had worked in the research laboratories at Exxon Research and Engineering in Linden and Clinton, N.J., for more than 26 years until retiring in 1996.
We have been blessed with the presence of Dezso in our lives. He will be deeply missed by his loving wife , Susan, of Kunkletown; stepdaughter, Amanda DeMontigny and husband, Thomas, of Whitman, Mass.; sister, Julia Szakos of Hungary; stepgrandson, Forrest J. Harrison of Providence, R.I.; and godson, Anthony Ditillo and wife, Elaina, of Summit, N.J. .
