Taylor Swift Reveals Her Intense Workout Routine for the Eras Tour

In addition to training, the 33-year-old also decided to quit drinking. “Doing that show with a hangover,” Taylor added, “I don’t want to know that world.”

The superstar’s preparation certainly paid off, as she found her inner strength throughout the process.

“I know I’m going on that stage whether I’m sick, injured, heartbroken, uncomfortable, or stressed,” Taylor noted. “That’s part of my identity as a human being now. If someone buys a ticket to my show, I’m going to play it unless we have some sort of force majeure.”
