President-elect Barack Obama and his wife Michelle Obama, with iPod and headphones in hand and both wearing gym clothes, left their vacation rental home at Kailuana Place in Kailua at 7:15 today for a 45-minute workout at the Semper Fit Center at Marine Corps Base Hawaii on Kane'ohe Bay.

The Marine base had little activity as the Obamas' motorcade headed to the gym.

Obama's gray shirt was soaked with sweat when he emerged from the gym at about 8:10 a.m. He was followed by a couple Marines in civilian workout gear and lifted his right hand to give a quick salute to a couple uniformed Marines standing not far away.

The motorcade returned to the neighborhood of their rental home at 8:21 a.m.
