CELEB BODY SECRETS - Revealed!

Learn how these stars get - and staybikini-ready for summer!

Khloé Kardashian

Khloé is a known gym rat, doing cardio intervals, weight training and resistance band and Bosu ball workouts five mornings a week. (Never skip "warm-up and stretch,” her longtime trainer, Don "Donamatrix" Brooks, warns.) But, as the reality star says, "Diet and exercise go hand in hand." So, to achieve real results, she began making small changes, cutting things like soda out little by little. Now, Khloé, 39, mainly eats for fuel. A typical lunch is "grilled chicken breast with a half portion of a simple starch, such as four ounces of yam or a half cup of white rice," she's explained, "along with a vegetable and a salad." Another tip? "I don't even look at a scale anymore," notes Khloé. "I think it's really unhealthy. I haven't in years. They're just numbers."

Sydney Sweeney

Though she's "never even tried coffee" and prioritizes hydration, Sydney's diet isn't the healthiest. "I eat sugar," she's confessed, admitting she also prefers "hearty" lunches like cheeseburgers. The Anyone But You actress, 26, makes up for it with exercise, sticking to activities she's loved since childhood-such as waterskiing, hiking and mixed martial arts - so that it doesn't seem like work. For a more "challenging" sweat session, Solidcore (a high-intensity, low-impact Pilates-inspired class) is her go-to. "It just makes me feel so toned and strong," Sydney says, "but also elongated."
