That pic is from Terminator 1 when he walks up the street punks. He was only a few years out of 1980 competition shape there. I would say 220.
His stats are posted everywhere different. You can never seem to find two that state the same. Although they are all fairly close. Louden's listing was fairly accurate, save for the waist. That is one that is almost always listed as 34inchs.
His weight in the Olympia's varied. 240 at the 74 was said to have been his biggest.
Nobody will ever know the true answers to these questions "what were his exact stats?" "what cycle did he take?!", but just looking at pics of him back then, who cares. He looked simply incredible.
