Actors Tamannaah Bhatia and Tusshar on Saturday launched Payal Gidwani Tiwari's book "Body Goddess: The Complete Yoga Guide For Women".
On her association with the author, Tamannaah said: "Payal has been training me for the last two and half months and I've experienced immense difference in my body already.
"Yoga is the only activity which helps you not only physically but also mentally. So I'm in favour of doing yoga as a daily routine just like brushing teeth."
Author Payal said her book - which contains a foreword by actress Sridevi - was a small contribution of "a drop in an ocean" from her end, and she chose Tamannaah for the launch as "she gets the holistic feel out of yoga".
Tusshar claimed his first experience with yoga was "hell" as he couldn't do any of the exercises. But later it grew on him.
"Yoga makes you feel liberated, more confident and calmer with a lot of peace of mind. It has made me really flexible and I'll never stop doing it," he said.
Actor Suchitra Pillai was also present.
The book was released on the occasion of the International Yoga Day to be observed on Sunday.
