Taylor Swift’s Eras Tour was not just a musical spectacle—it was a serious physical challenge. In a revealing new episode of her Disney+ docuseries, The End of an Era, the pop superstar opens up about the intense preparation required to perform for over three and a half hours each night, hitting every note and executing high-energy choreography with precision.

Six Months of Training for the Eras Tour

Before Taylor Swift kicked off the blockbuster 149-show run of the Eras Tour, she undertook a rigorous six-month physical training regimen. The 36-year-old singer explained that her longest prior live performance was only about two hours and 15 minutes—far shorter than the stamina-demanding Eras Tour concerts.

“I’ve never worked out this much in my life. It’s horrible,” Swift admitted. “I really had to up my game in terms of physical training.”

To prepare, Swift ran daily on a treadmill for months, practicing at the same tempo as the songs she would perform live while singing along. She noted that albums like 1989 and Reputation were particularly challenging due to their high-cardio demands.

Running 8 Miles Per Show: The Physical Toll

Each Eras Tour show featured roughly 45 songs, demanding Swift to run across enormous stages, scale massive platforms, and even fly through the air for numbers like “Delicate.” She revealed:

“Anything’s hard when you’re scaling a stage that goes the entire length of an NFL stadium. I think I run like eight miles in a show.”

This grueling routine not only tested her endurance but also required split-second precision during live vocals, intricate choreography, and multiple costume changes.

Backstage Challenges: Quick-Change Chaos

Swift also discussed the intense backstage preparations that fans rarely see. With multiple elaborate costume changes, each taking less than two minutes, mistakes were not an option. One mishap during the Evermore segment left Swift injured:

“I trip over the hem of my dress. Bust my knee. I skid the palm of my hand off. Hobble into the quick-change room. Blood’s coming down my hand. I’m changing into the Reputation bodysuit, the skin that’s flapping off, I just pull it off, more blood. They don’t have a Band-Aid back there.”

Despite the injury, Swift stayed on schedule and did not miss a beat during the live performance. Fans eventually noticed her bandaged hand, but she humorously shrugged it off:

“I was like, I am not acknowledging this. What? Nothing’s wrong. That’s always been like that.”

The End of an Era Docuseries: Behind the Scenes

The third and fourth episodes of The End of an Era premiered on December 19, 2025, with the final two episodes scheduled to drop on December 23. Fans now have the opportunity to witness Swift’s dedication firsthand—from her grueling training sessions to the chaotic yet flawless execution of her live performances.

The series not only highlights Taylor Swift’s musical genius but also showcases the intense physical and mental preparation behind one of the most ambitious tours of the decade. For aspiring performers and die-hard fans alike, it’s a masterclass in stamina, discipline, and showmanship.
