Actor Hrithik Roshan sure knows how to make his workout sessions interesting. On Saturday night, he took to Instagram and made everyone smile by giving all a glimpse of impromptu jig to Bollywood`s old songs including Amitabh Bachchan-starrer `Janu Meri Jaan` from the movie ` Shaan` and Mithun Chakraborty`s hit track `Jimmy Jimmy Aaja` at a gym.

"When bollywood hero suddenly hears 80`s music in gym. #braindead #totalloss," he captioned the post.  The first video clip showed Hrithik prancing around the gym, as someone off-camera likened it to Garba. In the other clips, we can see him dancing to the 80s` tracks.
