“I work out in the morning,” she said. “It just loosens up my body, gets me ready, keeps me strong. You know, injuries come when the muscles get weak or you over-work them. So you have to keep them strong, too.”

J. Lo is no doubt getting some killer cardio from her two-hour show as well, which she says keeps her on her feet and dancing the entire time.
