For better or worse, coverage of newly designated Vice Presidential candidate Paul Ryan includes his fitness choices. Everyone from The Daily Beast to Politico has devoted space to Ryan’s enthusiasm for the fitness workout regimen, P90X. And, according to a series of articles in Politico last year, Ryan has encouraged colleagues to get in on the interval training system, a 90-day series that relies on a strategy called “muscle confusion” to tone muscle and encourage fat loss.

"Nothing against rock hard abs,” joked Rachel Maddow in a segment devoted to news organizations' enthusiasm for covering the Congressional P90x fad. “I plan to get those after I learn Spanish. But 10 articles [on P90X in Congress] from the premier Beltway news source?”

Ryan is hardly the only politician to go public with his fitness preferences. President Barack Obama and the First Lady regularly mention their morning training sessions and pick up basketball games. Former Presidents Bill Clinton and George W. Bush were often seen jogging, in what is hardly a modern phenomenon: Theodore Roosevelt trained with a Jiu Jitsu master during his presidency and Gerald Ford -- who turned down offers to play professional football in the NFL after graduating from University of Michigan, where he was an All-American college player -- was known for his skiing, swimming, golf and tennis playing while president.

Still, if Ryan’s bid were successful, he may be the first VP to claim devotion to TV fitness. Often thought of as the provenance of busy working parents in suburban living rooms, P90X and other programs like it, have devoted followings, even among those with the resources for personal trainers and home gymnasiums.

So what other boldface names love P90X? Read on.

So usually, I wake up and do an hour of cardio, then an hour of P90X or yoga, then a half-hour of warm-up [during show rehearsal]. I do that six days a week.</blockquote>
