Los Angeles: Dutch model-actress Doutzen Kroes says regular ballet training with a professional ballet dancer, Mary Helen Bowers, helps her stay in shape.
The fashion magazine, Victoria`s Secret model also says that dance is one of the best exercises that helps her get a slim body and she takes regular sessions from the trainer who also helped actress Natalie Portman for her role in `Black Swan`.
"I work out three or four times a week. I do a mix of boxing at a gym in New York and ballet with Mary Helen Bowers, who runs Ballet Beautiful and helped get Natalie Portman in shape for `Black Swan`," femalefirst.co.uk quoted Kroes as saying.
"It`s tough because it focuses on specific areas including the inner and outer thighs, butt and abdominal area and arms. Every morning after a workout with her, I feel so sore in places I didn`t know I had, so it really works and I enjoy it," she said.
"I also think that working out with a woman makes a difference as she understands what I want to look like. Men see things differently," she added.
The 28-year-old, who has two-year-old son Phyllon with choreographer-husband Benjamin Millepied, insists that becoming a mother has forced her to take better care of her body, so she has to watch what she eats and work out more often.
"When you`re younger you think you know everything, but I know my body better now than 10 years ago. I run around like crazy since I had my son, but I`m lucky and have good genes so my stomach has never been a problem area. However, I know I have to work out and eat healthily now," said Kroes.
