Taylor Swift’s record-making, Ticketmaster-breaking Eras Tour required intense preparation artistically—and physically, as well. That’s according to Miss Americana herself, named on Wednesday as Time’s 2023 Person of the Year. 

Prior to the Eras Tour, Swift approached touring a bit lackadaisically, “like a frat guy,” she told the magazine. When it came to Eras, however, she began training six months ahead of time, running on the treadmill and “singing the entire set list out loud” daily—“fast for fast songs, and a jog or a fast walk for slow songs.”
