Kate Beckinsale has one of the best bodies in Hollywood and has to keep in shape for roles like in her new movie Total Recall.

The 39-year-old brunette beauty has always had a great physique but sometimes has to take it up a notch.

Kate has been a longtime client of yoga instructor Mandy Ingber who says she works with the actress several times a week when she is in town.

"She is extremely dedicated to her practice and keeps it pure," Mandy shared.

Kate also works with Ramona Braganza for her cardio workouts and core-specific exercises.

The mother-of-one has said that she only goes to the gym when she has to or if she has to "bulk up or slim down for a film."

Kate is married to director Len Wiseman and recently revealed that her husband has a "fetish" for seeing her in bed with her male co-stars.

She had to shoot a bedroom scene with Colin Farrell for Total Recall and told OK! that it's "always easier for Len and me" but "awkward" for the other person.
