You have to be fit to do the acrobatic work Pink does on tour. The singer works out six times a week for 90 minutes a day, according to Pop Workouts. Leg day comes twice a week, and she also works her chest and shoulders two times a week. Clearly, it's paid off.

For Cameron, fitness should all be about building up your most important muscle: your heart. In Oprah Magazine she revealed how she starts her workouts.
