Kal Szkalak was a bodybuilding phenom who burst onto the scene in 1976, winning the AAU Mr. America at age 23. The following year, he won the heavyweight Mr. Universe (defeating Mike Mentzer). His legs were lacking, but his upper body ranked among the best of the disco years. In 1978, Szkalak tried to organize a pro bodybuilders union; he failed. That same year, he placed fifth in the Mr. Olympia, and he promptly struck a martyred pose--arms outstretched, head to one side--saying later he was "crucified by the bodybuilding hierarchy of the day." Szkalak never competed again in the IFBB after his first and last IFBB pro contest; he was 25.
I find this one to be the most interesting. I have never heard his name prior to this article.
