Khloe, 39, completed various exercises inside the industrial space, surrounded by others with the exact same yoga mat and equipment in front of them.

One Instagram video first showed a blown-up shot of Khloe posing in an all-black workout set from her collaboration with the activewear brand, which was placed on the wall.

The Hulu star’s shrinking butt and tiny waistline were at the center of the shot, possibly acting as motivation for those working out.

The rest of the video showed Khloe in another workout set once more as she posed with fans and led the front of the demo class.

Khloe had her hair tied back into a tight bun and showed off her sweaty and tiny figure while doing jump squats and leg lifts.

The event was completed with Fabletics-branded backpacks for the attendees, healthy wraps for lunch, and a meet-and-greet with the Hulu star.

Khloe launched her collaboration with the fashion brand in early September.

OPENING UP

While Khloe has made it known that she is quite the fitness guru, the reality star shed more than 60 pounds in recent years, leaving fans concerned over her shrinking frame.

Earlier this month, the Good American founder revealed her true clothing size after undergoing her dramatic weight loss transformation.

The star listed items from her closet for sale, which included a Michael Kors Collection set.

The top, the listing revealed, had “no size tags” but “fits like [small].”

Meanwhile, the pants were “marked a size US 0,” though the listing stated that they fit “like US 2-4.”

The Good American founder listed the items for $3,995.

Back in December 2022, Khloe revealed her incredibly small jean size while boasting about a special delivery from her denim company.

As Khloe zoomed in on the pants, her size could be seen on the tags, revealing that she wears a size two.

CONCERN FOR KHLO

In 2022, Khloe started noticeably slimming down.

The change came amid her ex and baby daddy Tristan Thompson’s cheating scandal, which worried some fans.

Even Khloe’s family took notice of her dramatic weight loss transformation.

During an episode of The Kardashians, her sister Kim Kardashian, 43, said to Khloe: “You look very skinny.”

She added that their younger siblings also took notice of the weight change, saying: “Not that I’m trying to out them but Kendall and Kylie [Jenner] did say they were a little concerned for you because you look really skinny and I said I think she’s a bit stressed.”

Khloe appeared to smile at herself, asking: “And Kendall said it? The model? Wow.”

Kim went on: “I said, ‘No guys, it’s fine.’ I said, ‘You absolutely have every right to be concerned but I’m telling you, she’s fine.'”
