Just a point of information...
The 700ish competition deadlift attributed to Arnold probably stems from the fact that Arnold got a lot of press coverage for winning a stone-hoisting contest in Munich soon after his first Universe win.
I believe he lifted the 680 lb stone higher than anyone else... but it was a sumo-style contrived lift on a platform (probably best equated to a power rack pull from the knees)... still impressive, but not a genuine deadlift.
If Arnold could have managed any of these lifts you noobs are attributing to him the Weider mags would have reported and photographed every one of these retroactive claims. If he really ever had a 20 inch arm he would have been photographed with a tape on his arm... hell, he didn't even deny Arthur Jones' measurement of 19.5 (slightly pumped).
Hate to admit it... but Squadfather is dead-on with this one.
I've shaken hands with a 300lb off-season Markus Ruhl and even he didn't have a 20 inch arm or 60 inch chest.
