Karisma Kapoor, Bollywood actress and mother-of-two, credits yoga for helping her shed 24 kilos in nine months post pregnancy and says the traditional system of exercises can work wonders for children too.

"I think it is great to get the kids started on yoga. My daughter is learning yoga at school and she practises it with me sometimes. My son is only three years old and too young to do it but he sits and laughs and giggles at poses," Karisma told PTI over phone from Mumbai.

The actress, who debuted in Bollywood at the age of 16 and went on to give award winning performances in Zubeidaa, Raja Hindustani, Dil To Pagal Hai and Biwi No 1 has launched her first book, a primer on motherhood and losing weight.

While younger sister and actress Kareena has gone public about her passion for yoga, Karisma says she "chanced upon it late in her life."

"I was a non-believer for long even though it was working so well for my sister. Yoga takes longer to show results but it's really good as it cleanses your body of toxins and helps you breathe better, sleep better," says the actress.

In "My Yummy Mummy Guide: From Getting Pregnant to losing all the weight and beyond," the 39-year-old writes about the different emotions women go through – dealing with the baby, managing the family, tossing about on sleepless nights – and advocates yoga as "a great form of relaxation."

Once a "hard core gym person", Karisma says that within a month of taking up yoga she could see "dramatic results in her body and mind."

Her routine includes yoga four times a week with fast music like those by Rihanna, Adele, Pitbull, Jay-Z and other hip-hop artists followed by a meditation session at her home in Mumbai where the actress currently lives with daughter Samaira and son Kiaan.
