Blake Lively’s Trainer Says This One Change Has Made Clients Lose 10 Pounds in 3 Weeks

If there’s one thing we know about celebrities, it’s that they have an uncanny ability to tone up fast. Whether it’s trying to lose weight post-pregnancy, or building muscle mass for an upcoming movie, the secret weapon for reaching their fitness goals always comes down to one thing: A personal trainer. These trainers have a major impact on how successfully a celebrity can transform their body, but not everyone can afford one. So, we spoke with Don Saladino, celebrity trainer to stars like Blake Lively and Scarlett Johannson, about his secrets for toning up quickly—and his advice is a much more, well, doable, than we thought.

“First of all, I always tell my clients to increase sleep,” says Saladino. “I’ve increased peoples’ sleep by ninety minutes a night and they’ve instantaneously lost ten pounds in three weeks.” Sound too good to be true? Think again. Not only is sleep essential to repair muscles, it also balances the chemicals in your body that could ultimately affect your weight. “People don’t understand, they think they’re just going to work off the weight but hormonally, your body goes into the tank if you don’t sleep. Your hormones stop producing testosterone and growth hormones and your cortisol levels get thrown off which can actually lead to weight gain.”

But that’s not all. Saladino, who also recently became a metabolism-boosting food advocate, believes that what you eat and drink is also essential for transforming your body. Other than eating Turkey and Salmon to ensure you’re healing from your workouts effectively, he advises adding Apple Cider Vinegar into your diet as well. “I’m really into Apple Cider Vinegar,” explains Saladino. “When I’m trying to get someone leaner, the main things I recommend for their diet is Apple Cider Vinega.”

However, the major lesson that Saladino reemphasizes to his clients is that recovery through sleep is the most influential change you can make in your routine. “If sleep isn’t dialed in, and you’re not getting seven to nine hours a night, it’s going to be very difficult to develop the physique you want.”
