Shinto Mathew, who teaches kalaripayattu at his institute in Sector 37, says, ``Kalaripayattu is one of the most rigorous forms of self-defence. Earlier, only boys used to take up this art, but now, we have a lot of girls learning it, too. The ratio of girls to boys in our classes is 60:40. Bollywood inspires a lot of youngsters to set up their fitness goals. When 'Baaghi' released last year, we started getting 30-35 calls per day from women!``
