Kim Kardashian shows off her impressive back muscles in a workout clip filmed by sister Khloe Kardashian

Kim Kardashian was active on Instagram on Thursday when she shared a video clip in her Stories.

The clip showed the 43-year-old mother of three – who had just closed one of her businesses – impressively pumping weights and showing off the chiselled muscles in her back.

The recording was recorded by her younger sister Khloe Kardashian, 39, who was heard adding commentary.

Kim wore a black Lululemon racerback sports bra and matching high-waisted leggings during her gym session.

She wrote over the video, “Workouts with @khloekardashian really do it for me,” and added a laughing emoji with her tongue sticking out.

Kim's gym ensemble was topped off with a pair of sporty and trendy black and white slip-on sneakers.

Her long dark hair extensions were held back from her face with a pink clip and she wore fingerless gloves to navigate the gym equipment.

While recording her sister, Khloe exclaimed, “Oh, my God. Oh my God. What are you training for?'

A slightly irritated Kim replied, “Life!” before Khloe shouted, “The Olympics!”

In the background, Drake's 2013 hit Worst Behavior played over speakers in what appeared to be a home gym.

Khloe continued, “Holy f*ck! You're going to prank me later!' as she caught her sibling's corners.

Drawing from her own Instagram Stories, the Good American founder reshared the video and added her two cents.

She wrote to her millions of fans: “Haha, I'm beyond annoying, but look, you're killing it!”

The post comes after Khloe posed with her two children as she shared photos from their New Year's Eve outing.

Earlier this week, she took to Instagram to connect with her 311 million followers, writing, “Deer Valley NYE 2023! Hello 2024!!'

The proud mum, who shares True, five, and son Tatum, one, with ex Tristan Thompson, added: 'Happy, healthy, blessed and magical love wishes.'

She was stylish in a long, soft, black coat, while her daughter wore a similar style in a soft pink shade.
