The Washington Post reports:
But one habit endures: Obama has gone to the gym, for about 90 minutes a day, for at least 48 days in a row. He always has treated exercise less as recreation than requirement, but his devotion has intensified during the past few months. Between workouts during his Hawaii vacation this week, he was photographed looking like the paradigm of a new kind of presidential fitness, one geared less toward preventing heart attacks than winning swimsuit competitions. The sun glinted off chiseled pectorals sculpted during four weightlifting sessions each week, and a body toned by regular treadmill runs and basketball games.
