"Not worked out in three months cause I'm not supposed to look fit for my next... Missing the weights," Shahid tweeted.
Last seen in "Teri Meri Kahaani", Shahid did not reveal which film he is preparing for. But he said he will start shooting for it soon.
"Shoot starts in 10 days... will be back on set after a while. Every movie feels like starting all over again, and every time I feel like I have no clue what I'm gonna do with the character," he tweeted.
"I guess every actor is searching for that moment of truth somewhere between action and cut.
I guess to find any part, an actor has to look within and not outside if he wants it to be honest," he added.
