The moment you decide to join the film industry as an actor or actress, the important fundamental requirement is you need to be fit. If you do not have the right kind of physique then your chances drop immediately. Speaking about it, you have seen how many actors and actresses sweat it out at the gym.
For some it is a requirement and for many it is a mania. But now, this mania has spread to people from other departments as well. Apparently, it is not just the heroes and heroines, even directors and producers have begun to hit the gym and taking different routes to fitness such as martial arts, aerobics etc.
Well, they are not keen to become actors but this has more to do with making themselves look good in TV channels and while they are onstage. In a way, when a person looks fit and fine, it sends a very positive vibe among the onlookers and in an industry where visual appeal matters, they are taking the right route.
