Kendall Jenner expressed her longing for the summer heat by posting an inviting throwback photo on Instagram flaunting her slim bikini body.

The 19-year-old "Keeping Up With The Kardashians" star and rising model on March 1, Sunday encouraged her 20 million plus Instagram followers to join her in dreaming of a tropical respite, with a picture of herself in a floral bikini, according to the Huffington Post.

Jenner aptly captioned the throwback photo: "TAKE ME BACK." The photo, taken during one of her past vacations, featured Kendall on a giddy yacht wearing a purple, printed two-piece and a backdrop of bright blue seas, the US Weekly said.

As Kendall Jenner flaunted her sleek bikini body, her Kardashian sisters continued to share their respective weight loss and fitness battles online, the Inquisitr reported.

Kourtney Kardashian recently posted a photo of herself showing off her waist trainer. The new mom and reality star claimed she has been using it only for "a little waist training," as she also regularly works out in the gym.

Meanwhile, Khloé Kardashian proudly shared a selfie showcasing her newly discovered "baby abs" on Instagram last week. The youngest Kardashian has been working hard at the gym with personal trainer Gunnar Peterson for sometime now.

"I'm not where I want to be and who knows if I ever will be. But I am healthier than ever and due to my consistent workouts, I am slowly seeing results," Khloé posted. "Hi baby abs!! I see you!!! I hope to meet your other ab friends soon (yes I'm talking to my muscles. I've never met most of them before)," the caption of her abs-flaunting photo read.

Kim Kardashian, on the other hand, has frequently shared about her current diet plan on social media, according to E! News. The "Keeping Up With The Kardashians" reality TV star is now following the Atkins weight loss plan, which is essentially a high fat low card diet that includes protein, non-starch vegetables and healthy fats.
