Kim Kardashian is excited to get in the best shape of her life.

The reality TV star, who recently gave birth to her daughter, North West, is ''super motivated'' to get her pre-pregnancy figure back and wants to look better than ever, according to her personal trainer Tracy Anderson.

The celebrity fitness expert told ''It's a tough time, and a lot of women feel like it's a huge mountain to climb to get back, but Kim, surprisingly, has had the totally opposite reaction to other moms. She's like, 'We're going to be so good. It's fun, I feel great!' She just loves the whole process. From our talks during her pregnancy, I thought she was going to be really concerned [about her weight] once the baby was out, but she's just not...She's in baby heaven. She's excited to get started, but she's really calm about it all.''

Tracy revealed that she personally plans to help Kim, 32, to lose weight and has devised a gruelling exercise program that will see her work out six days a week.

She explained: ''It will definitely be lots of muscular structure...In the beginning, it's key getting the deep abdominal muscles back and making sure that you get the strength back in the right layers. She's not going to be doing any typical crunches or anything like that.

''She promised me she would be the best student ever, and I promised her that I would do it personally for her, that I would go to her myself and get her back.

''Kim is super motivated. She's all in. Pregnancy is actually an opportunity for women to look better than ever. And [Kim] will.''
