Bipasha Basu who is a fitness freak in real life will now be seen essaying the role of a gym instructor in Rohit Shetty's comedy flick All The Best.

A source reveals, "Bipasha's performance is very natural in the movie since she is acting in a role of a gym instructor.

Gymming and working out has always been a part of the actress's routine. When the role was initially narrated to her, she was quite excited with the fact that she will be working out in the movie and for the movie. "

The source continues, "She also has donned a different look. The model-turned actress has grown her tresses and comparatively has a sporty look. She is paired opposite Ajay Devgan and plays the role of his wife in the movie.

A major chunk of the movie was shot in Goa and the actress was often seen working out after their pack up. This made the other cast members such as Ajay Devgan, Sanjay Dutt, Fardeen Khan, Mugdha Godse and even the director Rohit Shetty work out and be a regular at the gym. "

"Due to her regular work outs, the director use to pull her leg by saying that she should not take her role so seriously, for the fact that even after shooting and pack up she was seen pulling people to work out, " adds the source.
