Actress Priyanka Chopra is training hard for the Mary Kom biopic, but her trainer says he doesn't want her to build extra muscles and ruin her femininity.

Priyanka, 30, plays the Olympic bronze medalist in Sanjay Leela Bhansali's film, being directed by Omung Kumar.

Physical trainer Samir Jaura, who is working with Priyanka to get the right look for the character, told IANS: "We are working on building her muscles, but I don't want her to build extra muscles. I want her curves to get the right look, and not ruin the femininity."

Jaura vouches for Priyanka's hard work and dedication.

"Priyanka was very close to her father. When he passed away (June 10), I thought it will not be easy for her to come out of it, and the film will get delayed. But she is highly professional and she joined back within eight days and started working hard to get the right look," he said.
