Hilary Duff joins trend of artists training vocals on treadmills ahead of tours

Hilary Duff is turning to an unusual but increasingly popular training method to prepare for her upcoming The Lucky Me tour, singing while running on a treadmill to build vocal endurance.

In an exclusive interview with People, the singer revealed that combining cardio with live vocals has become a core part of her preparation routine as she gets ready for her summer tour, which will feature both her classic hits and new material from her latest album Luck... or Something.

“Using the treadmill and singing is really great for your endurance,” Duff said, explaining that the technique helps her adjust to the physical demands of performing while moving.

“It’s about figuring out how to sing and what parts you can sing when your heart is really pounding.”

She added that the method is especially useful for high-energy performances that include dancing and stage movement, where breath control becomes essential.

Duff joins a growing list of artists adopting similar training approaches.

Taylor Swift famously incorporated treadmill singing into her pre-tour preparation for the Eras Tour, running through full setlists while adjusting pace to match song intensity.

Other performers, including Miley Cyrus, Demi Lovato, Lizzo, and Tate McRae, have also experimented with treadmill-based vocal training or performance prep in recent years, reflecting a broader shift in how artists prepare for physically demanding tours.

Beyond cardio training, Duff is also focusing on structured fitness and strength work as part of her overall preparation.

She has been using the Ladder fitness app, which provides guided workouts and personalized training plans.

The singer said the platform helps remove guesswork from her routine, allowing her to stay consistent with professionally designed workouts while adjusting intensity as needed.

Duff emphasized that fitness has become a non-negotiable part of her lifestyle, not only for performance readiness but also for overall well-being.

“I need to train four times a week, and that’s that,” she said, adding that staying strong helps her feel more energized, sleep better, and show up fully for both her career and family life.
