Kate Beckinsale visits her yoga instructor six times a week.
The 'Total Recall' actress is dedicated to daily sessions with celebrity fitness instructor, Mandy Ingber, who claims the star is "very disciplined" when it comes to toning up her figure with Hatha/Vinyasa Flow yoga practice as well as maintaining a healthy lifestyle.
Mandy told E! News: "She has great genetics and a great attitude and is very in touch with her body, I started training with Kate four years ago, and now it's the only exercise she likes other than hiking.
"She doesn't eat any sugar whatsoever, basically a lot of chicken and salads. She's very disciplined! She's one of the strongest people I've ever worked with! She can do anything."
Mandy - who has also worked with Jennifer Aniston - even claims Kate is a natural when it comes to the difficult poses performed during the workout.
She explained: "Kate is also great at warrior three pose, which tones the glutes, inner thighs and calves, as well as chair pose and half moon pose. These are all balancing exercises that use a lot of muscles and we'll add in hybrid moves like squats and holds to exhaust the muscles for extra benefit."
