Chuck Sipes was one of the strongest bodybuilders of all time. Chuck, who won the 1959 IFBB Mr. America, 1960 IFBB Mr. Universe, and 1968 Mr. World Bodybuilding titles, could also could perform many incredible feats of strength.

As he was training to accomplish a 600 pound(!) bench press, Chuck used to train using a variety of techniques involving heavy supports and negatives — he even had a special handle welded to the underside of his pickup truck which he used to lift and support the whole affair.

Sipes would first lift the pickup truck as high as he could with his arms then wedge his legs underneath. In the top position, he estimated that he was supporting 1600 pounds.
