Mandakini Gupta, New Delhi: Sheefali Narang is an instructor at a posh South Delhi gym, Olympia that she runs with her husband. But behind the instructor's physique is a story of almost fairy tale triumph.

Ten years ago Sheefali was 80 kilos on a 5 feet 7 inch frame. Obesity hounded her most of her adult life.

Says Sheefali, "People always teased me because I was a really fat. They would call me fatso or baby elephant. I was always very worried about how I looked. Even my mother and brother were always after me. They said who will marry you?"

However, at 21 she took on the Herculean task of shedding 25 kilos in less than two years.

"I was sick of looking at myself in the mirror and seeing a fat girl all the time. I wanted to feel and look good. You just need a dedicated instructor and someone to guide you through the exercise and diet routine. And you will win the battle, says Sheefali.

Not only did Sheefali manage to lose weight she also met her soul mate at the gym, her instructor Rahul Narang, whom she later married.

Says Sheefali, "He motivated me through my struggles and anxieties. I am really happy to be married to him."

Sheefali is expecting her second child so it is a bit of a rest from gym duties now but she already has a new challenge ahead- to loose weight all over again after her baby is born.
