Melbourne, Nov 1 Aussie supermodel Lara Bingle has revealed the secret behind her super slim body - daily run, with after-dinner chocolate as an indulgent reward.

The 22-year-old fiancie of cricketer Michael Clarke revealed her exercise regimen and diet, including a personal trainer twice a week, half-hour beach runs and weights.

Bingle said she eats bread, pasta and chocolate and loves a good dessert, however, she tries to stick to healthy foods such as fish, salad or vegetables.

"Of course, I have days I don't want to train. But I like to indulge a bit when I eat, so I don't feel as guilty if I've trained," the Daily Telegraph quoted her as telling new health magazine Your Body.

Bingle admits she and Clarke are very competitive when they exercise.

"If I'm going to run with him, I want to beat him - and he will also want to beat me," she added. (ANI)
