The mother-of-one and reality TV star flaunted her curvaceous figure in a couple of "selfies" which she posted on Instagram. Kim, who has been training hard to shed her baby weight since giving birth to daughter North West last June, looked every inch the fitness fanatic in her latest photos. Posing in a revealing sports bra and black leggings, Kim struck a pose with her friend, rapper Tyga's girlfriend Blac Chyna, showing off her defined abs. "Getting right for the new year," wrote Kim next to the first "selfie". Kim and Blac then turned around for their second snap, leaving all focus on their pert posteriors. As the queen of selfies, Kim is usually quick to show her fans and 18million Twitter followers the results of her gruelling work-outs and dieting. Just four months after she gave birth, Kim posted a photo of herself in a revealing white swimsuit and captioned it "#NoFilter". Earlier this week the determined gym bunny, who likes running and weight training, revealed that her New Year's resolution was to "stay healthy and get in better shape for 2014." Kim also recently admitted that she used the celebrity favourite Atkins diet to help her in her quest to lose her baby weight. "I've actually been doing the Atkins diet & luv it", said Kim, responding to a fan asking for her secret. Sources spoke about Kim's carb-free diet saying, "With the exception of some cheat days, because she is realistic now, she sticks with it."
