Paris Hilton takes up body-building

London: Socialite Paris Hilton has reportedly started body building and is sticking to a high-calorie diet after her boyfriend Cy Waits encouraged her to do more exercises.

The 29-year-old socialite, who showed off a larger, more muscular figure when she walked down the ramp at a Brazilian fashion show last week, is said to have been inspired by her fitness fanatic boyfriend Cy Waits and is apparently now on a 3,500 calories a day diet to keep her energy levels up for her intense workouts, reports femalefirst.co.uk. "Paris has always preferred to stick to dieting all the time to maintain her figure. But since she`s been dating Cy, she`s got the bug. It`s a massive turnaround and now she`s working out so much that she`s often been seen on the treadmill drinking a milkshake," said a source. Hilton`s new daily exercise routine includes weightlifting, bench presses and running on the beach with Cy, 35. Hilton is delighted with the changes in her body and is planning to keep up her new regime. The source added: "She wants to change her image and get properly healthy. At first she was unsure and it took some getting used to, but now Paris loves her new body. And Cy loves it too - he`s always talking about how hot and gorgeous she is." IANS
