Kim Kardashian had fans doing double takes when she hit the gym bright and early on Friday morning.

The reality star, 43, appeared nearly topless as she completed her exercises in a nude sports bra.

Kim kicked off the New Year with a variety of early morning workouts, including weighted hip thrusts, hamstring curls, and step ups.

The influencer – who worked out on Friday with her sister Khloe Kardashian – accentuated her slim figure with black leggings while taking her workout to the next level with fingerless gloves.

She wore her hair slicked up into a no-fuss bun and appeared to have hardly a trace of makeup on her face for her rigorous workout.

The reality star broke down her workout on her Instagram account, and tagged her trainer Senada Greca in the clips.

First, Kim started off ‘leg day’ with a series of Romanian Deadlifts followed by hamstring curls.

Kim then explained she has been challenging herself this year by increasing her weights. As she did another workout on a Technogym machine, she appeared in pain and exhaled deeply.

‘We’re going for heavier weights this year. Set small fitness goals and stick with them,’ she explained in writing.

Kim then did a series of hip thrusts with her feet placed on a nearby bench.

‘I hate these hip thrusts! She makes me do them three times a week! Consistency is key! We use the leg extension machine and a bench! Creativity is also key!’ she posted with a winking emoji.

She followed it up with a trickier-looking exercise, step ups.

Kim tapped her back foot on a small disc on the floor as her front leg bent on a bench. She then pulled herself up with the help of a bar.

‘Step Ups are deadly too but a must!’ she wrote.

The final workout she posted was the standing cable abductions. ‘Slow it down with control, good,’ her trainer said as Kim tugged on a cable with her ankle.

Kim doesn’t seem be slowing down her workout routine as she enters 2024.

On Thursday, she exercised with her sister Khloe Kardashian.

Kim wore a black Lululemon racerback sports bra and matching high-waisted leggings for her gym session.

She wrote over the video, ‘Workouts w @khloekardashian really do it for me,’ adding a smiling emoji with its tongue sticking out.

While recording her sister, Khloe exclaimed, ‘Oh, my God. Oh, my God. What are you training for?’

A slightly exasperated Kim answered, ‘Life!’ before Khloe shouted, ‘The Olympics!’

Khloe continued, ‘Holy f*ck! You’re gonna f*ck me up later!’ as she caught her sibling’s angles.
