Irvin ‘Zabo’ Koszewski

Posted on Wednesday, December 5th, 2018 by John Wood
After winning the “Mr. New Jersey” contest in 1948, “Mr. Middle Atlantic” in 1950 and placing high in a few other regional bodybuilding shows, Irvin ‘Zabo’ Koszewski relocated to California and stepped into history. Like every great bodybuilder on the west coast, he started training at Vic Tanny’s Gym and spent most of his days on the sands of Muscle Beach. He took up right where he left off in the contest department, winning the Mr. Pacific Coast and Mr. Los Angeles contests in 1953 and added the Mr. California title in 1954.

Zabo also did very well in the AAU Mr. America contests placing thirteenth in 1950, fourth in 1952, third in 1953 and third again in 1954. He also competed in the Junior Mr. America contest in 1951, 1952 and 1954, placing fourth, third and second, respectively. It’s not hard to see why Zabo won “Best Abs” in nearly every contest he entered.

Zabo was a safe bet for an Abs trophy, in fact he won “Best Abs” in every bodybuilding contest he ever entered, including four times in the AAU Mr. America contest and three times in the Junior Mr. America Contest.
