Mariah Carey loves to show off her toned body.

In several of her music videos, including Loving You Long Time and Hate U, the singer struts her stuff in a bathing suit. The 43-year-old also often posts photos of herself in her beachwear.

How does she maintain her toned figure? Carey's personal trainer Bernardo Coppola spilled her secrets to Life & Style magazine in May.

"We do a lot of swimming, aquatic exercises, cardio and weights for toning," he said. "Working out, dedication and specific nutrition... is what makes Mariah sculpted and lean."

During her pregnancy, however, the singer reportedly gained approximately 70 pounds. After giving birth to Monroe and Moroccan, Carey said she dropped 30 pounds in three months under the Jenny Craig eating plan.

"Pregnancy was probably the best and the hardest thing I'll ever go through," she told Shape magazine in the May 2013 issue. "I know for a lot of women, it can be wonderful and relatively easy. But for me, it was like 'Okay, honey, do you have to do everything the hard way?'"
