Taylor Swift has her own secret to meeting the tight performance schedule and the duration of up to nearly 3 and a half hours per night of The Eras Tour.

The Eras Tour is Taylor Swift’s largest and longest-running tour ever, with 152 shows in 20 countries over 2 years. For each show, Taylor Swift performs nearly 50 songs divided into 10 different parts for more than 3 hours. To accomplish this, the artist must have high physical, mental and emotional endurance.

Before the tour was held, Taylor Swift regularly performed cardio exercises to improve cardiovascular health and endurance. Every day, Taylor runs on the treadmill while singing the entire playlist out loud. She runs fast for songs with exciting rhythms, and slows down for softer songs. Taylor also followed a three-month program of strength training, body conditioning, lifting weights at the gym and dancing.

According to Marie Claire, the pop superstar sticks to a healthy, balanced diet on weekdays and eats to his heart’s content on weekends. “I try to keep my diet simple, not too extreme. I don’t like creating too many unnecessary rules. I know what’s good for me,” Taylor shared.

The Wildest Dreams singer eats a lot of salad, yogurt, buckwheat topped with ham, cheese, fried eggs, nuts, fruits and vegetables. On weekends, she “pampers” herself with her favorite foods including burgers, fries, ice cream or cookies. Taylor also focuses on adding protein with lean meats, fish, poultry, eggs and beans to help restore muscles. Before going on stage, she often has a snack to gain energy. During a few minutes break backstage, she will choose dishes that are easy to digest.
