Bollywood stars work hard to make their films hit and get totally immersed in their characters. Soha Ali Khan is working on a new movie `Joe B Karvalo,` and is playing the role of a police inspector.

To play her character to perfection, she is now learning martial arts at Recreation Club located in Shastri Nagar in Andheri (West). Her trainer is Chitah Yajness Shetty, the Bollywood popular martial arts teacher for over 30 years.

Yajness Shetty says `Soha is very dedicated and hardworking. She is learning very fast. Every girl should learn the art for self defence so that they can defend themselves, since police appears to be having a problem reaching everywhere. It should be made mandatory in all schools and colleges.`
