To have glorious moments on stage, Taylor Swift had to trade in months of extremely harsh training.

In an interview with TIME, Taylor Swift revealed the harsh behind-the-scenes behind her historic Eras Tour . In it, the pop star said she did not have any personal time for herself while carrying out her tour schedule this year.

“I know this tour will be harder than anything I’ve ever done before,” Taylor Swift declared before revealing that she had practiced for 6 months before her first concert.

The singer born in 1989 said that every day she runs on the treadmill, while singing loudly all the songs planned for the concert. Taylor also spent three months practicing dancing to make the tour stage the most beautiful and perfect.

“I want to practice thoroughly so I can joke with fans without losing concentration,” the star revealed, “Learning choreography is not my strong point.”

After the concert ends, Taylor Swift will spend all her time resting in her bed. The female singer even asserted that she could not speak because she sang continuously for three hours. “Every time I take a step, my feet scream because I’ve been wearing high heels for so long. I know I will step on that stage whether I’m sick, injured, heartbroken, upset or stressed. If someone buys a ticket to my show, I will perform unless we encounter some unforeseen circumstances.”

According to TIME, 2023 is a completely explosive year for Taylor Swift and part of the reason is thanks to the Eras Tour. At present, the tour is estimated to earn about 2.2 billion USD in revenue in the North American market alone.
