To prepare for her role as Black Widow, the Tony Award-winning actress trained four to five days a week, doing a 45-minute to an hour session starting at 6 a.m. She checked certain milestones every 12 weeks, such as a 245-pound deadlift, pull-up series, one-legged pistol squat, and push-up repetitions with a 45-pound plate on her back.

“I do the same fitness regimen as my big muscle man trainer,” said Scarlett, describing her exercise regimen for Avengers: Age of Ultron. “A lot of it is endurance, stability and strength training.”

While avoiding traditional cardio training, she did sprint training, battle ropes and kettlebells, and incorporated Olympic lifting, gymnastics, hot yoga, combat training and SLT Pilates into her routine. She even added MMA training, per superhero Jacked.

“I like to work up a sweat. I’ve tried Pilates and yoga and all of that and like to try different things, but I always come back to good old-fashioned full-body athletic workouts.”
