He's a flexible dancer, but actor Varun Dhawan, who has attempted contemporary dance in a song for "ABCD 2", says it's not an easy style. Besides, he admits the film was taxing on him.

"For the song 'Chunar', I learnt dance in the sense that I should be able to perform non-stop... the emotion has to come through dancing. It is a contemporary dance choreographed, and very pure," he said.

"This film was taxing, it tired me. Contemporary dance is not easy to do...it is like poetry in motion. I took a big bite of chocolate after completing the song 'Chunar'. My mother loves this song," Varun added.

"ABCD 2", directed by Remo D'Souza, also stars Shraddha Kapoor. It is releasing on June 19.
