Not very likely. Do you have a source for this? For comparison, Bryce Harper, one of the strongest MLB players and a physical freak, squats 405. And that&#x27;s with modern training and nutrition.<p>Also compare to the CURRENT world record squats for a man of Sacks&#x27; likely size in the 1960s, and you&#x27;ll see how unlikely this is.<p>(Edit: I looked it up. Looks like Sacks did indeed set a CA state record with a 600-lb &quot;power lift&quot;, which is slightly different from a squat, but certainly close enough.
