Demonstrating What It Means to ‘Live Well,’ Dr. Joseph C. Maroon Enters His 5th Ironman World Championship in Kona Hawaii

“Dr. Maroon, who is Chairman of the GNC Medical Advisory Board, knows a lot about what training, physical conditioning and proper nutrition can achieve. But, he notes, preparing for the Ironman requires strengths that go beyond the merely physical. “The mental battle is far harder than the physical,” he said, “and you undergo a wide range of emotional highs and lows: from self-doubt and intimidation of seeing others with seemingly iron quads and bionic arms pass you, to the unbelievable elation of crossing the finish line. It’s all about confronting one’s own fears and self-doubt and fighting the urge to quit with every step you take.”
