Khallas girl Isha Koppikar is an evergreen stunner. No wonder that she is a hot favourite for item numbers in Bollywood. How does she keep herself so trim? Is she on diet? “Not at all,” she smiles and says, “I do yoga, I also dance and exercise. And then, I practice Taekwondo, a form of martial arts. I eat both veg and non-veg but then I know where to stop. “I do weights thrice in a week. I visit gym two to four times in a week. I believe yoga has tremendous power that helps you a lot.”
