Taylor Swift’s Intense Workout Routine For Eras Tour

Taylor Swift's Eras Tour was a monumental undertaking, showcasing her musical journey through decades of hits

The singer revealed intense training for a flawless three-hour show, featuring over 40 songs, a dozen costume changes, and multiple dance numbers.

The "Style" singer said, "I knew this tour was harder than anything I'd ever done before by a long shot."

"Every day I would run on the treadmill, singing the entire set list out loud. Fast for fast songs, and a jog or a fast walk for slow songs."

The "Anti-Hero" singer kicked her workout sessions into high gear six months before her first show in Arizona.

"Learning choreography is not my strong suit," Taylor said. "I had three months of dance training, because I wanted to get it in my bones. I wanted to be so over-rehearsed that I could be silly with the fans, and not lose my train of thought."

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."

Taylor continued, "I know I'm going on that stage whether I'm sick, injured, heartbroken, uncomfortable, or stressed."

 "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."

Taylor Swift is the second richest self-made woman in music, with an estimated net worth of $740 million, according to a list Forbes.
