On the search I did, got him training arms and getting ready for some sort of show. Didn't read much about him though, but got the impression of high sets, moderated weight..the whole volume thing. Actually never heard of him, but was muscular and well balanced of what I looked up.
When posing, in one of the vid's, he had more oil on him than the gulf oil spill. Guess they did that back in the day. Good Luck.
