India, Dec. 21 -- Two new episodes of The End of an Era, released on Friday, offer an intimate look at Taylor Swift beyond the spotlight. The pop star revealed that during the first half of The Eras Tour, she went through two breakups. "The show was what gave me purpose, and what I could use to get out of bed," she said, adding that the tour itself "has never been the hard thing" in her life. The episodes detail the intense physical preparation behind the three-and-a-half-hour show. For six months, Swift trained daily by running on a treadmill at the tempo of her songs while singing them out loud. Each performance involved nearly eight miles of running, with the 1989 and Reputation sets demanding the most cardio, far exceeding her previous two-hour shows. Meanwhile, the behind-the-scenes logistics were equally demanding. Outfit changes lasted 1 minute and 15 seconds or less, with the fastest being 39 seconds. Her stylist revealed there were 20 quick changes, achieved with two dedicated dressers and four changing rooms across multiple levels of the stage, connected by a pulley system operated by crew members. Taylor also spoke about her relationship with fiance, American football player Travis Kelce, noting that touring had historically strained past relationships. That changed with Travis , whose similarly demanding career meant he embraced her "big life", She also revealed that his appearance in the I Can Do It With A Broken Heart skit began as a joke until she realised that he was serious about stepping on stage. htc...
