John Fitzgerald Kennedy said, "Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity."  Though not Jack's most eloquent moment (perhaps he had Marilyn or missiles on the brain), I know exactly what he means.  After I modeled for the new Daddyhunt campaign, they asked me if I would be interested in writing a health and fitness blog.  I accepted with a self-imposed mandate to approach writing about fitness in a JFK-approved fashion:  from a cerebral and not a body-centric perspective, from a scientific and not superficial one.  Thinking such a task might prove painless at worst (I have countless bylines in all of the major fitness publications) I set to reviewing the blog entries and member comments that had come before me, and discovered painless it was not.
