Read on to see 7 ways Bebe Rexha stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She’s All About Body Positivity

“I was in Florida doing WWE Wrestlemania. The day I flew in, I had a little time off to go to the pool. I said to my manager, ‘Will you just take a video of me?’ I just wanna see what I look like. And when she played me back to the video, I said, I'm kind of, to me, it's okay to have a little moving parts and pieces and the little indentations—it's sexy to me. That's sexy. We were never really taught that. Like how to love ourselves and how to love imperfections,” she told Access Hollywood.

2. She Does Leg Day

"Time for legs," Rexha wrote in an Instagram Story chronicling her lower body workout. Smart choice. The largest muscles are in your lower body, and thus they burn the most fat. Your backside if the biggest source of myokines, which can do amazing things. Some help increase fat-burning in both the liver and skin tissue; others improve the function of the vascular system. Some improve the immune response; still others help our digestive system by improving communication between the pancreas and intestines. There’s even some evidence that myokines released through exercise may influence cancer cell growth.

3. She Mixes Up Her Workouts

Bebe knows the value of a good sweat session. Here’s a perfect 4 minute workout for you to try at home: Perform burpees for 20 seconds. Don’t worry about counting reps—just set a timer and get as many as you can. Afterward, rest 10 seconds, and then repeat for four minutes. Over time, you can progress the length of the work interval, but keep the ratio of work to rest at two to one (so if you build up to doing burpees for 30 seconds, rest 15 seconds between sets).

4. This is “Key for Me”

“I will say that sometimes when I’m really tired, and I don’t have time to wash my face, I have a little trick. It's actually something I learned from a makeup artist back when I worked in retail and sold perfume. He’s like, “Listen, if you’re super tired and you can’t even wash your face, and you just use a makeup wipe, the one thing you should still always do is moisturize.” So, sometimes when I’m really exhausted, I don’t really go in with the soap and water. I know it’s not the greatest, but I’ll just use a couple of face wipes and then moisturize my skin really well. That’s key for me!” she told WhoWhatWear.

5. She Was Diagnosed with Bipolar Disorder

“For the longest time, I didn’t understand why I felt so sick. Why I felt lows that made me not want to leave my house or be around people and why I felt highs that wouldn’t let me sleep, wouldn’t let me stop working or creating music. Now I know why,” she said on Twitter, revealing her bipolar diagnosis. “I was very fearful,” she told Self magazine. “I didn’t want to think there was something wrong with me.” “My mom would call it code red,” Rexha said. “A day before [my period started], I would feel like my world was ending ... I would get into these funks and be really depressed and not want to leave my house.”

"“That was my worst fear all my life: going crazy,” she told Self. “I felt like me opening up to my fans was me finally saying, ‘I’m not going to be imprisoned by this.’ And maybe it’ll make somebody not feel imprisoned, in that moment, if they feel like they’re going through a rough time. That’s why I decided to really open up and to free myself from that.”

Bebe Rexha, the singer being Better Mistakes, is currently under the sun, and is sharing some snaps with her followers, including one of her in a neon green bathing suit and red hat. The caption? "🍓🥝." "🔥🔥🔥," commented artist Dennis Leupold. (You might also say, to paraphrase one of her songs, "Baby, I'm Jealous.") How does she stay so fit? Read on to see 5 ways Bebe Rexha stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She Mixes It Up

In an interview with Health, Rexha opened up about her health and wellness. She says that her workout routine is all about variety. Rexha and her trainer like to mix up what type of exercise they do each day. “One day we’ll do yoga; one day we’ll do Pilates,” she said. “We can run one day or box, which is my favorite."""

2. She Works Out When She Travels

Rexha has a busy schedule and has to travel all over the world. You’d think that she wouldn’t have time to workout when she’s on the road. However, she tells Health that she makes time for exercise when she travels. “When I go to different places, I’ll try to run or go to the gym—or I’ll take cycling classes or boxing classes wherever I am.”

3. She’s True To Herself

Rexha is all about staying true to herself. She tells Health that she has ignored the advice other music executives have given her, as she wants to be as authentic as possible. “I’ve never followed that ‘play the game’ thing. I’ve just been myself. I’ve had people tell me, ‘That’s why you’re not as big as you could be’—which is fine. You don’t tell me what to do—you cannot judge me or put me in a box or tell me how I need to look.”

4. She Feels Happy With Her Body

Rexha is open about her struggles with her body. She says that she has felt pressure to lose weight in the past. However, she is working on being happy with herself and her body. “I see pop stars who are super thin,” she says to Health. “I could definitely get there. I’ve done it before, where I was 120-something pounds—and I was just miserable. I was always cold, never eating; I had no ass. Now I look at those pictures like, ‘Oh my God, I was so skinny.’ But I wouldn’t go back there. Even for this shoot...a lot of people would probably kill themselves working out. I’ve been not eating perfect or starving myself—I had chicken Parmesan the other night, Thai food the night before. I’ve just been enjoying my life. Then I was kind of bummed because I weighed myself. I was like, ‘Oh my gosh, dammit, I gained, like, six pounds, and I have my Health shoot!’ But then I was like, ‘You know what, when will I ever be ready?’ That’s just nonsense. I think you have to do what’s best for you.”

5. She Can Laugh At Herself

Rexha is also open about her struggles with her mental health. She tells SELF that her way of coping with the bad times is by finding humor in the situation. “It’s important for me to laugh at myself sometimes, and also spread information, and normalize it, because it makes me feel better instead of writing a sobby ballad. Which you totally could do—there’s not anything wrong with that. But I like to be sarcastic about things sometimes. It takes away the pain and the hurt.”
