The 37-year-old supermodel - who has daughters Valentina, eight, and Sienna, five, with ex-husband Marko Jarić - admitted her kids are used to always seeing her in sportswear because working out is an essential part of her life.

She told America's Glamour magazine: "During my everyday life I am in sports clothes - my children know that! I drive the kids to school and after that I go to the gym, if there is a day I don't do that, my kids ask, 'where are you going?' 

"That is my everyday life, I can't function if I don't have my exercise or I don't meditate. That's how I have to start my day to wake me up."

The Brazilian beauty admitted she has an incredibly "athletic mindset" and is proud of her new role as Puma's women's training ambassador.

She said: "I am very athletic, I have an athletic mindset so I am passionate about working out and fitness. I have been a fan of Puma for many years because of how they represent women, what they stand for and how they inspire women by providing apparel and shoes so they can reach their own goals in a fashion forward way." 

When it comes to working out, Adriana believes people need to find their own goals and motivation, with music helping her to stick to her routines.

She said: "Everyone has their own story and the first thing they have to do is to what to change their life - that is the most important thing of all. From there, look at what your goals are, who do you want to be, where do you see yourself and from there you go to working out, nutrition, choosing the right workout gear - that will affect your consciousness. 

"The key thing is to find a work out you like and stick to it; you need to keep moving. I usually listen to music, it wakes me up and motivates me, it gets me in the zone."
