P90X creator Tony Horton is a vocal advocate for regular exercise and a healthy diet, but when he's around his fans in Congress, he doesn't mouth off about it.

"It's kind of not my place," he said. "My place is to just come and work them out and talk about exercise and fitness, I don't talk policy with these guys."

Horton's workout program P90X, which solely uses the body instead of props like exercise balls and weights, has become increasingly popular with members of Congress. At first it was just Reps. Heath Shuler and Paul Ryan doing it in a corner of the House gym, Horton told Yeas & Nays, but now he can count Reps. Aaron Schock, Shelley Moore Capito, Jesse Jackson Jr. and Bill Shuster among his fans.

Instead of voicing his opinions to his congressional buds, Horton said he's taking his message directly to the public. He "brought it" all over Washington this weekend, on a multiday trip to the city, speaking at the National Press Club on Friday and then warming up participants at the Press Club's annual 5K Saturday morning.

"So this is me giving a speech in Washington. Whoa. Where's my teleprompter?" he said Friday at the luncheon where he complimented first lady Michelle Obama on her work to curb obesity.

He also referenced that morning's small earthquake before leading the audience in a workout session.

"I brought that from California with me," he said. "It's a great way to warm up."
