Rimes loved chanting so much, she released an album called CHANT: "The Human & The Holy. "As I started meditating I started chanting and singing. And as I felt what was coming through needed to come through and felt good, I would press record on my phone and get it down, then expand it from there," she told Forbes. "Chanting became part of my journey in learning to take my own voice back," Rimes explains. "I feel like so much of it has been given away outwardly, but I've never really used this incredible instrument I have for my own healing."

"Boxing is one of the best workouts you could possibly do. A two-minute round doesn't sound like much, but when you're moving constantly and throwing punches, it wears you out. And boxing workouts really build up your stamina," she once said. 

You won't find Rimes goofing off in the gym. "I'm serious about my exercise. I don't just doodle around. I see people at the gym talking on their cell phones. If they think their bodies are gonna change, you've got to put in the effort!"

"Nourishment usually looks like high-quality, healthy, whole foods, but sometimes nourishment is the cake, the chips, the pizza, and the mac and cheese," LeAnn tells Women's Health. "It's all a balance." She told the magazine she usually eats leftovers for lunch, for example. "Our leftovers range from mushroom and poblano tacos in almond flour tortillas, to smoky white bean and greens soup, to a delicious chicken and veggie stir fry," she explains.

"I think it was the biggest gift I've ever given myself," Rimes told Forbes about checking into a clinic to help with her anxiety and depression nearly a decade ago, "to recognize when enough was enough and to ask for help. It was the beginning of the past eight years of my life, of allowing myself to open up in a different way, and really shift myself into a different headspace." If you need help, don't hesitate. "I began confronting things I ran away from," she says, "from the time I was a child, just to survive in the public eye. Growing up the way I did, with all eyes on me, it has taken time to really connect with my true self. As the daughter of parents who divorced at 14, at the height of it all, I had to shut it off to be able to thrive and contain my work. So, when I decided I wanted to change the way I was experiencing life, it led me on this journey."
