Khloé Kardashian shows off washboard abs in pink bikini: 'Gym motivation has arrived!!!!!'

Khloé Kardashian is setting Instagram ablaze with a pink bikini photo.

The reality star and entrepreneur took to social media on Saturday to share a photograph of herself posing in a sparkly magenta bikini from the line she co-founded, Good American.

"Sparkle Swim," Kardashian captioned the photo, guiding followers to the link in her bio section to purchase the Sparkle Demi Top.

However, it wasn't just the outfit that followers were talking about. Many of the comments were focused on Kardashian's toned body — specifically, her defined abs.

"Gym motivation has arrived!!!!!" Kardashian family friend Simon Huck wrote, along with a series of fire emojis. "Yessssssss body!" another follower chimed in.

Despite being known for her discipline in the gym, the reality star has shared how challenging it has been to be compared to her sisters Kim and Kourtney Kardashian in the past.

"When the show first started, I was very secure. Very secure. And then, during the first couple seasons, I became insecure because of the public, um, opinions of myself," Kardashian told Andy Cohen last June during the Keeping Up With the Kardashians reunion. "Then I had, I think, a good run of being secure, and then, I think recently, I've become now insecure again. So I guess it just goes... You know, up and down."

When the host asked if she felt like Kim and Kourtney received preferential treatment because of the way they looked, Kardashian responded honestly.

"Oh, 100%," she replied. "We did so many photoshoots where they would receive racks and racks of clothes, and I was told by so many different stylists, I was given about two or three pieces of clothing, that's it, and not to worry 'cause I'll be in the background anyway. Like, I wouldn't be in the forefront. It would always be them two and me behind them. So, not even, it was never a question. It was a fact, and it was very blatant, as well."

These days, Kardashian has found a way to make her intense fitness regimen more about feeling healthy than looking a certain way. An advocate of blending cardio and strength training, she continues to share her workout journey on social media.

In February, she posted two photos of herself working out her upper body, showing how she had progressed in just a few months.

"About 3 months apart," she captioned the post, tagging her fitness coach Joël Bouraïma. "Let's go. We are sculpting my back and arms."

Kardashian has frequently stated that working out at the gym her "therapy." She made the statement in an Instagram Story, and continued by saying "I don't think anyone works out better or stronger than someone that's frustrated, angry, mad [or] determined."

"Let it all out at the gym and that's what I'm about to do," she added.
