It makes life so much easier when you can just say 'I'm human' at the end of the day."

I grew up as a horseback rider and a volleyball player so honestly when I got a gym membership in New York, I thought I was going to die.

Bella [Hadid] is also very naturally gifted in beauty so she can also go whenever she wants to go to the gym.

My fitness inspiration has always been athletes, my whole life. Serena Williams is a great friend of mine and Ronda Rousey - we did Sports Illustrated together. Obviously, following powerful women and seeing their bodies and how hard they work is really inspiring to me.

I used to go on runs, it's kind of hard for me now unfortunately in Paris because it's a little bit hectic. My knees aren't that great, so recently I haven't been on the treadmill that much but that's why I like to box on a soft floor. It's good for me.

I think it's so important to practice what you preach - whether you're into riding cows to work or eating a burger after boxing, just do what you're telling your fans you're doing because you have to be real with them because they look up to you.

When I moved to New York, leggings were always a staple piece in my closet and I'm always with leggings, a T-shirt, a cool jacket and shoes cause that's what would be easier for me when I was a kid.
