Between attending security briefings and poring over the emails of every American, the Leader of the Free World has his hands full. And yet, presidents always seem to find time to work out.

Obama had a basketball court built at the White House. George W. used to mountain bike around his ranch. Taft, who topped out at 350 pounds, well, he used to eat an entire tray of macaroni and cheese then just sleep it off. (Kidding. He hired a personal trainer and rode a horse for ercise.")

GQ Fitness's favorite president, John F. Kennedy, considered ercise to be "a matter of concern to us all," which is why, this President's Day, we share with you his vision for an America where everybody lines up in formation to do jumping jacks.
