Former ballerina Zoe Saldana stays strong and lean by mixing up her workouts — while she's a devotee of Pilates, she works out with a trainer to keep her motivated and not bored. Zoe also avoids extreme diets, taking a more balanced view when it comes to healthy living. "You can't forget that you only live once — you have to enjoy the pleasures of life, and you also have to enjoy the work in life," she told O, The Oprah Magazine. "That means that if you like to eat, then work out, be healthy. Keep that heart strong and healthy!"
