Given her drastic 21-lbs weight loss recently, some fans have expressed concern that the star is “too skinny.”
Kim, 41, flexed the intense-looking regimen on Friday.
She shared an Instagram Story video of her thin legs in tight black leggings lifting a sizable weight on a leg lift machine.
“Early morning workout,” she captioned her update.
The minimalist wood flooring of her $60m Hidden Hills complex once shared – and co-designed by – ex-husband Kanye West, 44, was visible.
In a second video shared the Kardashians star took things up a notch.
She then lifted the same weight but with just one leg.
“One leg extension,” she wrote as her left thigh lifted the unit alone.
Machines like hers run for $2.8K – and the “early morning” workout came as many fans are hoping she’ll slow down.

Kim – now bleach blonde – ignored growing backlash on Wednesday as she told fans about a “painful” tightening treatment she had on her stomach.
The mother-of-four shared a photo of her midsection with sore-looking red bruising on it on her Instagram Stories.
She captioned the shot: “This is a game changer!!!
“I did morphous laser to tighten my stomach. I think this is my fave laser but it’s painful lol but worth it.”
And this week, she also shared medical records showing her “body fat percentage” to her hundreds of millions of Instagram followers.
The scans revealed that Kim’s bones are stronger than 93% of the general popular based on her age and ethnicity.
The famous reality star then went on to the show and explain that “a year ago [her] body fat percentage was at 25 percent and now it’s at 18.8 percent.”
One wrote after the updates: “Can they just go a week without some kind of procedures done? A few days? Is that too much to ask?”
Another asked: “When will this woman give her body a rest?”
A third posted: “This has just gone too far now.”
‘DOWN 21 LBS’
Kim has faced concern over her appearance since she admitted to dropping 16lbs in three weeks to fit into Marilyn Monroe’s iconic dress for the Met Gala in May.
Kim recently hit back at critics of her weight loss, insisting she has dropped the weight in a “healthy way”.
“If I was starving and doing it really unhealthy, I would say that, of course, that’s not a good message,” the Hulu star told Allure.
“But I had a nutritionist, I had a trainer. I have never drunk more water in my life.
“I don’t see the criticism for other people when they lost weight for roles — they are [considered] geniuses for their craft.”
Then in June, Kim admitted she has lost even more weight after sticking to the ultra-strict diet.
She said on The TODAY show: “It actually taught me a lot about my lifestyle and my health, and since then, afterward, I continued to eat really healthy.
“I mean, I’m down 21 pounds now. I’m not trying to lose any more weight, but I have more energy than ever.”
Meanwhile, The Sun exclusively revealed that Kim’s family is concerned she’s losing too much weight and is “barely sleeping”.
She has admitted that studying to become a lawyer, looking after her four children and her bi-coastal romance with Saturday Night Live star Pete Davidson has taken its toll.
Kim did recently visit her boyfriend Pete in Australia while the comic filmed his latest film Wizards – where he’s been for weeks.
Despite the pair’s good times in Australia, fans think the two’s relationship may be on the rocks as Pete has posed in multiple pictures with actresses looking “single as hell.”
Her famous former rapper also recently “liked” one of Kim’s Instagram posts, despite rarely showing presence on social media.
The mom-of-four dropped other hints she’s “missing” Kanye, including posting a photo of a piece of art by James Turrell – an artist whom her former has been known to collaborate with.
Yesterday she shared Chicago, four, “snoring” much like she once posted Ye doing – her “Incredibles” tee shirt was another clue fans felt.
The SKIMS founder filed for divorce – which is not finalized – from the rapper in February 2021 after nearly seven years of marriage.
Amid reconciliation rumors, The US Sun can confirm Kim’s lawyer Laura Wasser shared on Friday in court that the exes are “working things out” and “communicating.”
Kim shares children North, nine, Saint, six, Chicago, four, and Psalm, three, with her ex Kanye.
