KIM Kardashian has flaunted her slender physique in a sports bra while working out in her home gym.

The Skims mogul started the new year with no days off, recently giving followers a glimpse into her difficult workout routine.

Kim, 43, shared multiple clips while on different exercise equipment inside the gym of her $60 million Los Angeles mansion.

She declared it was “leg day” as she flaunted her lean figure in a plunging nude sports bra and black leggings.

Kim’s abs were on full display as she lifted a barbell, did hamstring curls, completed a set of step-ups, added some hip thrusts, and ended with cable abductions.

The Kardashians star walked her followers through each phase of her routine, clarifying pointers from her trainer, Senada Greca.

Kim’s body looked slimmer than ever as her muscles were seen flexing throughout the entire gym sesh.

TOO SKINNY?

Toward the end of last year, Kim raised concern over her weight after posting a bikini picture from her vacation to Turks & Caicos.

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

One person reshared her photo on an 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.

BIGGER THE BETTER

While fans are constantly speculating about changes to the reality star’s body, some have questioned whether or not she recently got a breast augmentation.

Before wearing sports bras for her New Year’s workouts, Kim was last seen wearing a glamorous strapless gown at her family’s Christmas Eve party just last week.

She wore a grey dress that featured rings of puffy grey fur around the entire body of the gown.

One photo showed Kim leaning forward while blowing a kiss toward the camera, putting her cleavage on full display.

Her dress was pushing her breasts up, which made them appear to be larger than ever before.

Critics on Reddit pointed out what they believe to be Kim’s recent breast augmentation.

One fan asked: “Did Kim get her boobs redone?”

Another replied: “Yea remember when she ‘broke her shoulder?’ Boob job.”

“I thought her boobs recently looked the worse they ever had. I was like what did you do?! Bad boob job,” added a third.

A fourth said: “Kim’s implants are so obvious here.”
