According to her longtime New York-based fitness coach, Don Saladino, a balanced lifestyle is the foundation of fitness.
The fitness expert has worked with a number of A-listers, including Blake's husband Ryan Reynolds, Sebastian Stan, Anne Hathaway, Emily Blunt, and Cindy Crawford, emphasizes the importance of adequate sleep, plenty of water, and regular walks for maintaining a healthy physique.
One client, following this advice, lost nine pounds in three weeks by adding an extra 90 minutes of sleep per night.
Don told E! News, "'It's a fat-burner, and it's free,'" underlining the significance of seven to nine hours of sleep per night.
Blake herself admitted to Australian radio hosts Kyle and Jackie 'O' Henderson that she maintains a diet devoid of soy or gluten.
"I did no gluten and no soy," she said. "Once you remove soy, you realize you're eating no processed foods. So that's basically what I did. No processed foods and then working out."
Despite avoiding processed foods, Blake maintains a balanced diet of proteins, carbs, and vegetables, occasionally indulging in sugar, rice, and sushi.
Don outlined how he prepped Blake for her shoot in "The Shallows" in two months, revealing that besides regular workouts, she ate four small, nutritious meals a day, aided by a nutritionist.
He said: "This is not training a fitness competitor or a model. She's got to eat healthy. The way that we did it was the right way, and it wasn't through starving her."
