But fans were taken aback after this photo was posted to Kourtney’s lifestyle brand, Poosh’s official Instagram page on Wednesday.

It captured Khloe sitting on a rowing machine donning black leggings, a tight black top, and matching sneakers.

The Kardashians star rocked a full face of makeup and her blond highlighted locks in a sleek bun as she gazed at the camera.

“Moving more in 2024 may be a resolution, but it’s not too late for 2023. Poosh the link in our bio for the top workouts of the year,” the post’s caption read.

However, fans couldn’t get over Khloe’s done-up look and called her out for sporting full glam during a sweat session.

“You look awesome but who wears full makeup to work out?” one person commented.

Another complained about the Hulu star’s form in the snap and thought it wasn’t the most effective for the exercise.

“Girl get your arms off your knees!!! We’re gonna have proper erg form in 2024!” they wrote.PUTTING IN THE WORK

Khloe, 39, often shares pics and videos on social media from her at-home workouts.

Last week, the Keeping Up With the Kardashians alum posted a mirror selfie while standing in her gym surrounded by fitness equipment.

She wore another all-black activewear ensemble of a sports bra and leggings that showed off her pin-thin frame.

Days earlier, Khloe had her BFF Malika Haqq, 40, over for a gym session, and they posed in the mirror for a photo before their workout.

The ladies each rocked leggings and sports bras beside Malika’s three-year-old son, Ace, who came along.

“Bring your son to workout day,” Khloe added the caption.

CONCERNS FOR KHLOE

Fans have repeatedly expressed concern over Khloe’s shrinking figure as she’s lost a considerable amount of weight since her earlier days on reality TV.

“Khloe looks scary skinny now! Her ribs are out!” a fan wrote in the comments of a previous post of Khloe flaunting her tiny waistline.

“What stood out to me the most lately was the skinny-ness of her arms and around the shoulders…” another said.

Khloe’s sisters have also shared their worries after noticing the Revenge Body alum’s smaller physique.

“You look very skinny,” Khloe’s sister Kim, 43, pointed out on a recent episode of The Kardashians.

HOT MAMA

Meanwhile, Kourtney, 44, has been embracing her changed figure since welcoming her and Travis Barker’s son, Rocky Thirteen, on November 1.

She shared photos of her sporting an oversized black fur coat to her family’s annual Christmas Eve party and admitted it was the only piece of her wardrobe that fit her since giving birth.

“When not much in the closet fits yet and the boobs are filled with milk, throw on a cozy coat,” the Lemme founder captioned the post.

Fans gushed over the star’s post-baby body.

“Just had a Baby where??” someone commented.

“You looked SO beautiful,” another praised.
