Arthur Jones measured a bunch of bodybuilders in the 1970s. His measurements are absolutely different from Weider's
Arnold was great, but there were other guys who were bigger.

The largest muscular arm that I ever measured – or saw –was Sergio Oliva's, which, accurately measured, "cold" was 20 1/8 inches. Arnold Schwarzenegger's arm was 19 7/8, slightly pumped – probably 19 1/2 "cold". Bill Pearl's largest arm, his left arm, was 18 5/8 at a bodyweight of 222 in 1960 – at the 1971 NABBA Mr. Universe contest in London, his publicized arm size was listed as 20 1/4, but it was obvious to me that his arms were actually smaller than when I measured them in 1960, and it was obvious to anybody who saw the two men side by side that Sergio's arms literally dwarfed Bill's arms, and now you know how big Sergio's arms were at the time.
Casey Viator's arms were 19 15/16 at their largest when he was training in DeLand – and were 18 1/16 when he first came to DeLand, immediately after the Mr. America contest in 1970.
