Behati Prinsloo practices yoga to keep fit.

The 25-year-old model has revealed her fitness routine remains the same all year round because it revolves around yoga which she says has become a ''lifestyle''.

Behati, who along with actor Chad Dennis, is coached by personal trainer to the stars, Harley Pasternak, explained: ''I do yoga with Chad Dennis, and I have been training with Harley Pasternak. It's more of a lifestyle now instead of just training for a specific shoot.''

The Namibian beauty also maintains her slender figure by being strict with herself when it comes to foods which she can and can't eat.

She continued: ''I try to always eat as healthy and clean as I can.''

Behati's dedication to maintaining her svelte figure hasn't gone unnoticed.

After getting hitched to Maroon 5 frontman Adam Levine earlier this year, she was chosen to open the Victoria's Secret fashion show in London, which she describes as her highlight of 2014.

Speaking about the London show, which took place earlier this month, she said: ''It was such a huge honour and personal accomplishment, that was for sure the highlight for me.''
