Her name is Erin Oprea and she also trains Carrie Underwood and a bunch of other people. We do a lot of strength training and then when I’m on the road, we do circuits — sometimes with my band — or we’ll go to a class that’s close by, like if there’s a Soul Cycle we’ll go offsite to do that, which is really fun.”

Ballerini tells The Cut that she loves to listen to music in order to get herself through a workout or gym session. She says that her go-to workout songs are anything fast with motivational lyrics. “I usually listen to rap or EDM or anything that makes me want to actually push myself. I love anything Drake; I like Kendrick [Lamar] a lot. As for EDM, I like Zedd and Chainsmokers; anything with a beat drop.”

Ballerini says that she’s all about moderation when it comes to her diet. She tells The Cut that she lives by the popular “80/20 Rule” when it comes to food. “I try to eat really healthy 80 percent of the time, and then the other 20 percent of the time I’m eating cookies, pizza, and wine. I’m a red wine person.”

4. She Knows What Works For Her

Ballerini tells The Cut that she doesn’t listen to other people’s workout and wellness tips. She says that she knows what works best for her and sticks with it. “You have to find what works for you and not compare your health or your workouts or your eating patterns to anyone else’s, because everyone is different and everyone’s bodies are different. Learn what works for you, and be happy with that.”

5. She’s All About Endurance

Ballerini tells Shape that she does a lot of endurance based workouts, like running. She says that she does these types of exercises because they are the most helpful to her in her daily life. "I love to move around on stage. I love to be animated and run around. So being able to sing and breathe at same time, you need endurance. I work out on tour, off tour, and to get ready to tour. I recently took up running and cycling for endurance. I want to break a sweat every day."
