Taylor Swift's Eras Tour Treadmill Workout Will Test Your Endurance

It takes a great deal of endurance to build and sustain a career like Taylor Swift's. Since the early 2000s, the singer-songwriter has consistently produced chart-topping hits while managing to move seamlessly between genres — an impressive feat for any musician striving to maintain longevity in the business. It's clear that Swift is in it for the long haul, and shows zero signs of slowing down.

But her career isn't the only area of her life in which the "Cruel Summer" singer demonstrates tireless endurance; she approaches exercise the same way. After earning the title of 2023 Person of the Year, Swift sat down for an interview with TIME to discuss the workout regimen she had implemented in preparation for her highly-anticipated Eras Tour. "Highly anticipated" may be an understatement, however, considering that fans snatched up over 2 million tickets within 24 hours of their release. While the star jokingly told the publication that she used to tour "like a frat guy," Swift knew she had to up her game for a tour with a performance run time of more than three hours, in which she covers over 40 songs and implements elaborate special effects, costumes, and stunts. While some people regularly hit the treadmill every day, the "You Belong with Me" singer added a creative twist to the exercise.

Swift told TIME that she started physically preparing for the Eras Tour half a year in advance. Her exercise routine involved daily runs on the treadmill while she belted out all 40+ songs to be performed. The star described how she picked up the pace for more upbeat songs while slowing her stride to a brisk walk or jog for slower tracks. With the help of her gym in developing a personalized training program, Swift's workout routine expanded to include strength, conditioning, and weight training, which was followed by three months of dance training. The "Blank Space" singer adds that she also abstained from alcohol during this time.

If you're intrigued by the idea of adding some T-Swift karaoke to your treadmill workout, know that it may put your endurance to the ultimate test. While Swift has had her fair share of practice by now, the combination of running and singing may leave the rest of us out of breath. "Her lung capacity is higher than what the average person's lung capacity, who isn't doing a lot of things, may be," certified personal trainer Teddy Savage told Well+Good when commenting on her treadmill practice. "It is naturally strengthening her lungs and her body and her diaphragm to be able to do what she's doing on that treadmill."

While we might not have the vocal stamina of the "Bad Blood" singer herself, it may be worth trying to talk out loud the next time you're on the treadmill, rather than sing. Anyone who has ever casually chatted with a friend while on a jog, knows firsthand how this can make the workout even more challenging, especially if you're new to running.

According to experts at Runner's World, this is actually known as the "talk test," an effective tool that can help give us a read on our exercise intensity. If you find yourself struggling to talk while running, it's a pretty surefire sign that you're working at a higher level of intensity. During low-intensity activities, talking should be relatively easy with little strain. If you're only able to get out short phrases, this indicates you've reached a level of moderate-intensity exercise. During high-intensity workouts, you'll likely only be able to produce sounds rather than full words. Knowing this, the talk test can be particularly beneficial for runners looking to track the intensity of their workouts. But if talking while running seems too easy, and you're dying to belt out your own rendition of "22," go ahead and give it a go. But to quote T-Swift herself, just remember, "Are you ready for it?"
