Ryan’s gym time earned plenty of interest during the August recess, after Mitt Romney picked the Wisconsin congressman as his running mate. Ryan is a former personal trainer and has said he keeps his body fat between 6 and 8 percent. Even during his grueling stint on the campaign trail over the past month, he has been spotted in hotel gyms working out to P90X on his iPad.
Rep. Jeff Flake (R-Ariz.), welcoming Ryan back to Capitol Hill on Thursday, joked: "He's getting soft. We've got to get him back in the gym."
Ryan was also scheduled to speak at the Values Voter Summit on Friday.
