Kim Kardashian has five personal trainers

The reality star Kim Kardashian has hired an army of fitness gurus, including Gwyneth Paltrow's trainer Tracy Anderson and Jennifer Lopez's workout guru Gunnar Peterson, to help her lose her extra pregnancy weight.

Gunnar told In Touch Weekly: "She's in [my studio] a couple of times a week. Sometimes it's six days."

However, Tracy admitted the star was trying to take it easy after her health scare in March, after which doctors warned her to cut down on work commitments and excessive exercising.

The trainer said: "She will come in and work hard one week, and then have to take the next week off."

Nutritionist to the stars Harley Pasternak also revealed Kim has been experimenting with her 15-day Body Reset diet - which works by drinking liquid meals for the first five days of the cycle before consuming healthy foods in the next 10.

Despite her efforts, the magazine claims the 32-year-old beauty - who is due to give birth to her and Kanye West's first child - has gained over 60 pounds.

A friend said: "Kim's panicking that the weight will just keep on stacking on and will never come off. She's always played up her sex appeal so she's terrified she won't be able to get her body back after the baby is born."
