Illinois congressman Aaron Schock appears on the June cover of Men's Health magazine.
At 29, he's the youngest member of congress, and he may be the only one sporting a six-pack.
He's usually fully clothed when at the capitol, but he stripped down for a good cause. It's a campaign to inspire Americans to get fit.
Though Schock is a Republican, he said he admires first lady Michelle Obama's anti-obesity campaign. Schock said he wakes up at 5:30 a.m. so he can spend an hour or two at the gym.
