Kim Kardashian looks nearly topless in nude sports bra as she heads to the gym for an early morning workout

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 started the new year with a variety of early morning workouts, including weighted hip thrusts, hamstring curls and step-ups.

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

She wore her hair slicked back in a bun and appeared to have barely 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 the leg day with a series of Romanian Deadlifts, followed by hamstring curls.

Kim then explained that she challenged herself this year by increasing her weights. While doing another workout on a Technogym machine, she appeared to be in pain and exhaled deeply.

'This year we are going for heavier weights. Set small fitness goals and stick to them,” she explained in writing.

Kim then did a series of hip thrusts with her feet 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 disk on the floor while her front leg was bent on a bench. She then pulled herself up using a bar.

'Step Ups are also deadly, but a must!' she wrote.

The last workout she posted was the standing cable abductions. “Slow it down with control, fine,” her trainer said as Kim pulled on a cable with her ankle.

Kim doesn't seem to be slowing down her workout routine as she heads into 2024.

On Thursday she went to work out with her sister Khloé Kardashian.

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

She wrote over the video, “Workouts with @khloekardashian really do it for me,” and added a laughing emoji with her tongue sticking out.

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

A slightly irritated Kim replied, “Life!” before Khloe shouted, “The Olympics!”

Khloe continued, “Holy f*ck! You're going to prank me later!' as she caught her sibling's corners.
