Obama's workout time

"Although his presidency is barely a week old, some of Mr. Obama’s work habits are already becoming clear. He shows up at the Oval Office shortly before 9 in the morning, roughly two hours later than his early-to-bed, early-to-rise predecessor. Mr. Obama likes to have his workout — weights and cardio — first thing in the morning, at 6:45. (Mr. Bush slipped away to exercise midday.)"
