The singer’s trainer, Kirk Myers, said Swift would show up to the gym on her off days, adding that she approached her fitness “with the mindset like a professional athlete”

Taylor Swift’s workout routine is so intense — and so specifically tailored to the demands of her high-energy Eras Tour — that most people couldn’t do it, according to her trainer.

“It’s really hard, some people would probably throw up or have to lay down on the floor if they trained like her,” her personal trainer, Kirk Myers, told Vogue.

Myers, who founded Dogpound Gym and has worked with Tom Holland, Kaia Gerber, and Patrick Schwarzenegger, began training the singer 10 years ago during her 1989 album cycle.

“Her work ethic is just incredible,” Myers told the outlet. “I’m ready to be known as ‘Taylor Swift’s trainer.’ I don’t think there’s a cooler title out there.”

He shared how Swift, 34, got into shape for the Eras Tour, where she performed for well over 3 hours every night in a high-energy set that included choreography, singing, and playing piano and guitar. The tour first kicked off March 13, 2023 with a 44-song setlist, and won’t wrap up until December 8, 2024.

Swift’s workout routine was “tailored,” Myers quipped to the outlet, sharing that they approached her training “with the mindset like a professional athlete. There was an ‘off-season’ when she wasn’t touring and ‘in-season’ when she was.”

In the off-season, Myers said Swift is in the gym up to six days a week, two hours a day. In the gym, they focus on targeting her core, but he adds that Swift does cardio on her own, outside of the gym.

The “Cruel Summer” singer previously shared that her cardio included running on a treadmill — all while singing the concert’s setlist.

And when she is actively on tour, Swift still shows up to the gym.

“Taylor trained during the entire tour,” Myers told Vogue. “We would average two times a week. In-season training was more about maintenance, and so it was more like stability, mobility, biomechanics.”

All the Songs Taylor Swift Seemingly Wrote About Travis Kelce on The Tortured Poets Department

On her off-days, he told the outlet they worked with a chiropractor to help Swift recover.

“If you’ve seen the show, you know how intense it is physically. Imagine doing that three, four days in a row and then you finally have a few off days and you’re still showing up to [the] gym. That’s Taylor.”

And, of course, somewhere in there she managed to write and record her newest album, The Tortured Poets Department, which came out on Friday.

“Taylor is the most resilient person I have ever met,” Myers told the outlet. “It’s super-inspiring to see her consistently overcome obstacles and become better and stronger in the end. This also translates into her training and throughout her workouts.”

He continued, “I give her a difficult exercise or challenging workout, not only is she able to complete and push through it — but she also perseveres, moving forward into the next exercise. This ultimately makes her stronger, better, and faster.”
