As the ever-captivating Black Widow in the Marvel Cinematic Universe, Scarlett Johansson has to bring her A-game when it comes to physique and athleticism. But even at 39 years old, the acclaimed actress has managed to maintain an enviable figure – and she has her personal trainer to thank.

Johansson’s PT, Gregg Miele, recently revealed the six key strategies the star uses to stay fit and strong, both on and off the movie set.

1. Compound ExercisesRather than isolating individual muscle groups, Johansson focuses on compound movements that work multiple areas of the body at once. This includes exercises like squats, deadlifts, and pullups, which engage the major muscle groups for maximum efficiency.
2. High-Intensity IntervalsTo torch calories and build cardiovascular endurance, Johansson alternates between short bursts of intense exercise and active recovery periods. This HIIT-style training keeps her heart rate elevated and metabolism revved.
3. Functional TrainingJohansson’s workouts mimic the real-world movements and demands of her action-packed roles. This means incorporating exercises like battle ropes, kettle bell swings, and medicine ball slams to develop full-body power and stability.
4. Flexible Strength TrainingTo prevent injuries and maintain mobility, Johansson blends traditional strength training with dynamic stretching and mobility drills. This well-rounded approach allows her to train hard while staying limber.
5. Recovery and RegenerationProper rest and recovery are crucial for Johansson, who allows her body adequate time to rebuild and repair between intense training sessions. This includes foam rolling, massage, and low-impact activities like walking.
6. Nutrient-Dense DietTo fuel her workouts and support her active lifestyle, Johansson sticks to a diet rich in lean proteins, complex carbs, healthy fats, fruits, and vegetables. She also stays hydrated and limits processed foods.

By adhering to this multifaceted fitness regimen, Johansson is able to maintain her superhero-worthy physique well into her late 30s. Her trainer’s insights offer a glimpse into the discipline and hard work that goes into her action-packed roles.
