Bristowe has always loved working out and exercise. "I have always been a very healthy person," she says. "I started dancing when I was three years old, and was dancing at least six times a week until I was about 19… When I moved back to Vancouver that's when I got my certificate to teach spin, so I started doing that before the show. For me, it wasn't really about losing weight or anything like that, I was pretty happy in my own skin. I just loved the feeling of getting stronger."

Bristowe started weight training before appearing on Dancing With the Stars. "I talked to one of my friends who is a trainer and he was like, 'we gotta lift weights and we have to get you strong'," she says. "I was like, I really want to be strong going into this, mentally and physically, and so I started lifting like pretty heavy weights."

Bristowe makes decisions throughout the day to make healthy choices and keep moving. "At the airport I make sure I am not taking the tram to each gate and I will walk," she says. "I try and be very cautious of making small decisions and small goals for myself to keep me active. Airport food isn't the healthiest so I will find those little variety stores for hard boiled eggs or almonds and I make sure to drink lots of water."

Bristowe's attitude to health and fitness is to maintain balance and make room for cheat days. "Anything I do in life, I always want to work hard, play hard," she says. "So I'm still drinking my wine, I'm still eating my McDonald's on Sundays, but I am working hard through the week."

Bristowe tries to stay true to herself. "Especially with social media, the highlight reel of everybody else's life, I just think 'Be More Human' means being more forgiving to yourself, and learning from your own failures and being honest and open and having more conversations about where you are in life," she says. "Not just trying to put on what people want to see, but actually being who you are and loving yourself and doing your best."
