Would you really rather keep up with the Kardashians than sweat? That was a question I posed last year in this LA Times column. I asked it because physical activity rates are at an all time low, and yet we seem to have plenty of time available to watch TV. And this sorry state of affairs has led not just to expanding waist lines, but a serious health crisis. Exercise IS the cure for what ails you in most cases. There are few medical conditions that cannot be improved or ameliorated by physical activity.
