Bob Hoffman, Legendary US Olympic Weightlifting Coach and The Father Of World Weightlifting said of his father who was a Swoboda student, "So often I have said that my father had more muscles than I have seen since and we must remember that I am in the muscle business and that I have seen thousands of extraordinary physical specimens. He exercised incessantly and he could make most of any muscle group in his body feel like blocks of wood. I always believed that his exercises verged more on the tension type, rather than Functional Isometric Contraction,but there was a close similarity."
