    So, just how does Kacey stay so fit for her killer moments onstage? Her trainer, Erin Oprea, is big into working with celebs—some of her other clients include stars like Maren Morris, Carrie Underwood, and Kelsea Ballerini.

    Erin told Us Weekly that Kacey is a big fan of HIIT workouts, which usually involve 20 seconds of intense exercise followed by 10 seconds of rest, for four minutes total. The country singer also loves Pure Barre classes—so much so, that she brings a barre DVD with her whenever she travels, Erin said.

    Erin also said that Kacey pumps herself up for her workouts with some...interesting playlists. “Sometimes it’s not even in our language. I’m like, ‘What is this? How is this motivating you?’ But it makes her happy and I’m like, ‘If it makes you happy, that’s all that matters.’”

    “She looks incredible and has worked so hard,” Erin added (which, I totally agree there!).

    Lately, Kacey has also been revamping her mental health routine. She journals and does pottery to relax. Kacey makes extra time to ride her horse, too, “because that’s what makes my soul really happy,” she said. “I just want to continue to make healthy choices for myself physically, mentally,” the singer told Rolling Stone.

    As for what she eats, Erin said Kacey follows her 4x4 nutrition plan, which she explains is “a clean, healthy, balanced lifestyle so that they can still enjoy the foods they love, but in moderation.”

    The plan does allow for alcohol, although Erin mentioned that “I’m not saying you can drink as much alcohol as you want, but I try to limit them to two drinks a week, which a lot of people are like, ‘Oh jeez! I need wine every night, that’s bologna!’ But literally you can do that.”

    Honestly, if it helps make Kacey's onstage moments this iconic, I'm in.
