Sailor, who has battled body confidence issues, regularly opens up about her feelings. "I've grown up with a lot of body issues. I spent my entire life being so insecure," she told InStyle. "When I did my first bikini shoot, I was worried because I don't even have boobs; I'm a B cup. I don't have all of these intensified assets that many bikini models do. Why should I be considered sexy?" Modeling has aiden in giving her confidence to "own" who and what" she is "at such a bare, raw state," she explained. "I really felt like I was celebrating my body and my womanhood." More recently she shared about her struggles with body dysmorphia. "I've been so down on myself recently. Crying about my cellulite, letting the fat on my body ruin my day, getting mad that I'm not as skinny as I once was," she wrote in an Instagram post. "The body dysmorphia and left over eating disorder tendencies have been coming in strong. "As I come into myself as a young woman my body shifts and changes by the month, the 'control' I felt I once had over it has been completely stripped away from me. Hormones, emotions, growing pains."

Exercise is one of Sailor's healthy habits. "In general, I try to work out every day. A normal workout would start with cardio. I'm a big runner—I try to run two miles a day. Then I work out with my trainer at Work Train Fight, doing HIIT workouts like burpees and lunges. If I need a day off, I'll do yoga or something low-intensity," she told InStyle. 

Sailor will cut sugar out of her diet prior to a big shoot. "I start cutting sugar 10 days before. Every time I stop eating sugar, it's immediate, and when you're going to the gym every day, cutting out sugar changes the game. I see myself getting a lot more shredded," she said.

Sailor also understands the importance of hydration. "You want to be hydrated because it shows up in the way your skin looks, in the way that your body looks, in the way that you're acting and feeling," she told InStyle. "24 hours before a shoot, I'm drinking a crazy amount of water—I'm talking like three gallons."

Sailor eats "as clean as possible," she revealed to InStyle avoiding processed food. "Lots of lean protein. I'm vegan so I can't have grilled chicken or salmon, but I go for salads with quinoa and beans and fresh vegetables and then something light, like a sautéed vegetable dish, for dinner."

Sailor suggests taking walks, especially as a method of destressing. "I think that's a really underrated thing people don't do enough when they're feeling stressed out. Especially in the city, I'll put my phone in my pocket, put my headphones in, and I'll just play my favorite music and take a walk around the city. You just see all these different people of all different walks of life, and the art on the streets, and little fluffy dogs. All these little things remind you that, Okay, we're all in this together, we're going through it, you've got to make the best of it. That really helps me a lot when I'm feeling chaotic," she told Glamour.
