Kim’s, 43, shared clip featured her lifting a weighted barbell, looking slimmer than ever, especially when it came to her butt.

The Hulu star flexed her back muscles as she leaned over, pulling the barbell up and down.

Since Kim sported a black sports bra, her sculpted arms and back were fully visible.

Additionally, the ridges in her muscular legs were accentuated by the black leggings she paired the bra with.

“Workouts w/ @khloekardashian really do it for me,” the reality star captioned her post.

In September, Kim raised concerns after she posted a bikini picture from her vacation to Turks & Caicos.

In the photo, she posed in the sun while lounging in a chair by the beach.

Kim showed off some major side boob and a deep tan in a skimpy black bikini while relaxing on a pink towel.

‘IS KIM SHRINKING’

The Skims founder left her face out of the photo, instead focusing on her curves and tiny waist.

The billionaire businesswoman founder flexed her abs for the sexy snap.

One reshared her vacation photo on a popular internet forum alongside the caption: “Is Kim Shrinking? Why she built like that?” opening up the conversation.

“So i have a bony upper stomach and ribcage showing easily and what we’re seeing here on Kim isn’t normal,” a second agreed.

“How did she get to this size?” a third wondered.

MET GALA LOOK

In May 2022, Kim started dropping pounds in an effort to fit into Marilyn Monroe’s iconic dress for the Met Gala.

But her weight loss journey didn’t stop there as she continued to shed pounds in the following months.

A source revealed to The U.S. Sun that Kim hoped to maintain her thinner-than-ever physique, saying she “does not want to put on weight as she thinks she has never looked better than now.”

LOSING TO MUCH?

Kim’s sister Khloe, 39, has also been worrying fans with her weight loss.

In April, Khloe posted a video of herself in a nude mini dress to social media to promote The Kardashians.

She attended a lavish event in the clip while wearing the skimpy nude ensemble with a sweater loosely covering her shoulders.

Fans took to the comments to express concern for Khloe, noting that she looked much thinner than in previous years.

One concerned viewer wrote: “She should be used to change. Look at her body and face. Come on now.”

Another echoed the thought: “What happened to myy KOKO.”

Khloe isn’t the only Kardashian family member fans are worried about when it comes to shrinking figures.
