"I think my body endured a lot during rehearsals and the shoot. It was physically demanding and extremely challenging with swing pole and Cyr wheel section of the dance but all the sweat and bruises were definitely worth it as it gave me the opportunity to pull off something entirely new," Vaani said.
The actress said she is super "happy and grateful" that her performance is being loved and the song is being loved.
The song's choreographer Tushar Kalia called Vaani a hardworking actor and that he was amazed to see her commitment.
"She got so many bruises, she fell so many times and it was bad. Physically, it was very challenging but she never gave up and she never skipped a single day of rehearsal. It is because of her dedication, commitment and hard work that the song has come out so well! I'm really proud of what she has done in the song," he said.
Kalia added that the rehearsals for the song went up to three months.
"It's one of the most difficult songs I have ever choreographed. For the first time ever, an actress is attempting a routine that involves Cyr wheel and aerial rotating pole and both are very difficult routines to pull off even if you are a brilliant dancer," he added.
He added that when he shared the idea about the choreography with the film's director Siddharth Anand and Vaani, they were very kicked about it.
Composed by the duo Vishal-Shekhar, "Ghungroo" has been sung by Arijit Singh and Shilpa Rao.
The film is set to be a visual spectacle for quintessential action lovers, who will witness some jaw-dropping stunts.
Produced by Yash Raj Films, the high-octane film will release in Hindi, Tamil and Telugu on October 2.
