Kangna Ranaut has taken to yoga while shooting for 'Tanu Weds Manu Returns'.

The film, which is currently being shot in New Delhi, has her co-star R Madhavan also working hard on acquiring a toned physique.

But on Kang's list is making the film's director Aanand Rai lose at least 10 kilos by the time the film wraps up. Rai has apparently taken up the challenge and hopes to knock the inches off.
