Lily Aldridge ''completely changed'' her fitness regime since becoming a mother.

The 30-year-old model - who has four-year-old daughter Dixie with her husband Caleb Followill - has revealed working out is ''definitely'' part of her ''daily life'', but after she gave birth she had to alter her exercise plans, which led her to practise yoga, pilates and ballet.

Speaking in a video, which was posted on Victoria's Secret Instagram account, she said: ''Working out is definitely a part of my daily life.

''After I had my daughter, I completely changed my workouts. I started doing yoga, pilates, ballet, things that are more lengthening and I was more passionate about it.

''I love it and it makes me feel good to be healthy and strong.''

And the brunette beauty - who has graced the runway for the lingerie giant - has revealed prior to stepping foot on the highly coveted catwalk for the lingerie giant's showcase, all you think about is your preparation and working out as ''hard'' as possible.

She explained: ''Getting ready for the runway you are working out as hard as you can. There's not a moment when you're not thinking about getting ready for the show and wanting to give your all, because when you give your all you feel so much more confident on the runway.''

And the catwalk icon has revealed she ''always'' tells herself to be thankful prior to her catwalk shows.

She said: ''The final words I say to myself before I hit the runway is 'Always be thankful'.

''We work so hard to be a part of the show and I always feel so blessed that I get to be a part of this phenomenal experience and see how far I have come in my job, it's really incredible.''
